Release notes
Worker Pro: easing migration
From time to time Graphile Worker needs to make changes to the database, and these changes might cause pre-existing workers to fail in "interesting" ways. These breaking changes are noted in the release notes below, and typically you need to "scale to zero" to perform these updates - turn off all your existing workers and only then run only new workers.
Worker Pro is a proprietary plugin which, among other things, helps to alleviate this issue. It tracks the running workers and when a new breaking migration is required it has all old workers exit cleanly (once they've finished what they're working on) and no further old workers will be able to start up. Once all old workers have exited, the migration can go ahead as it normally would. This avoids the need to "scale to zero" as workers will communicate with each other to make sure the system as a whole remains consistent.

Pending
- BREAKING: Jobs and queues are now
locked_by
theirWorkerPool
's id rather than theworkerId
. Be sure to upgrade Worker Pro at the same time if you're using it! - New
addJobs()
JS method to enable efficiently adding a batch of jobs via the JS API - DEPRECATION:
quickAddJob
has been renamed toaddJobAdhoc
to make it clearer that it's for use in one-off locations (some felt the "quick" referred to the speed it executed, rather than the amount of effort required from the programmer) - We'll now warn you if you haven't installed error handlers on the pool, and will only install them ourself if needed
- Fixes bug where CLI defaults override
graphile.config.js
settings (by removing CLI defaults) - Fix bug where executable tasks had their stdout/stderr ignored; this is now output via logging (thanks @wineTGH).
- Fix race condition when multiple workers attempt to initialise the database at the same time
helpers.abortSignal
is no longer typed as| undefined
. It is still experimental!helpers.abortPromise
added; will reject whenabortSignal
aborts (useful forPromise.race()
)backfillPeriod
is now marked as optional in TypeScript (defaults to 0).
v0.16.6
- Fix bug in
workerUtils.cleanup()
where queues would not be cleaned up if there existed any job that was not in a queue - If errors happen writing to stdout/stderr (e.g.
SIGPIPE
), we'll trigger a graceful shutdown (and swallow further errors) workerUtils.cleanup({ tasks: ['GC_TASK_IDENTIFIERS'] })
now allows you to specify additional task identifiers to keep (taskIdentifiersToKeep: [...]
) in order to reduce impact on other workersgraphile-worker --cleanup GC_TASK_IDENTIFIERS
will attempt to keep all locally defined task identifiers
v0.16.5
- Add "timeout" to list of retryable error codes - thanks @psteinroe
v0.16.4
- Hotfix: remove website dependencies from worker module dependencies
v0.16.3
- Add "cannot connect now" to list of retryable error codes - thanks @psteinroe
v0.16.2
- Fix loading tasks on Windows (use URLs rather than file paths) - thanks @hiepxanh
- Add
cleanup
function to remove unused queues, stale task identifiers, and permanently failed jobs - thanks @christophemacabiau - Fix logger scope for workers - thanks @jcapcik
- Add
helpers.getQueueName()
to retrieve the queue name of the currently running job - Automatically retry certain internal operations on serialization failure or
deadlock detection (useful if you have changed your
default_transaction_isolation
toserializable
or similar)
v0.16.1
- Fixes issue importing task files that were written in TypeScript ESM format but exported as CommonJS.
v0.16.0
There's a breakdown of these release notes available on the new Worker Website, where we go into more detail about the headline features.
THIS RELEASE INTRODUCES SIGNIFICANT CHANGES, in preparation for moving towards the 1.0 release. Please read these notes carefully.
IMPORTANT: this release is incompatible with previous releases - do not run earlier workers against this releases database schema or Bad Things will happen. You should shut down all workers before migrating to this version, or use Worker Pro. (If you're upgrading from v0.13.0, upgrade to v0.13.1-bridge.0 first and add the Worker Pro plugin to that; deploy it across your fleet, and then proceed to upgrade to v0.16.0.)
General Migration Warnings
- 🚨 Drops support for node <18
- As of 24th October 2023, Node 20 is the active LTS and Node 18 is maintainence LTS; previous versions are no longer supported
- 🚨 Renames all of the tables
graphile_worker.*
tographile_worker._private_*
- We might change these tables in a patch release
- This has always been the case, these are not a public interface
- New naming makes it clear that you should not use them and should not rely on their schema being stable
- 🚨 Removes
maxContiguousErrors
- It wasn't fit for purpose, so best to remove it for now
- See #307 for more details
- 🚨 Removes
--watch
and watch mode in general- Now signal handling is improved and with people wanting to use ESM to define modules, it's finally time to remove the experimental watch mode
- Use
node --watch
ornodemon
or similar instead crontab
file is also not watched, so be sure to watch that too!- Fixes a lot of weirdness that can happen when you attempt to hot-reload tasks
- 🚨 Breaking TypeScript changes
- Lots of
any
changed tounknown
- In particular, errors in the event emitter payloads are now
unknown
rather thanany
, so you might need to cast
- In particular, errors in the event emitter payloads are now
- Payload is now marked as required in
addJob()
- Set to
{}
if your task doesn't need a payload
- Set to
- Lots of
New features
- Graphile Config and new plugin system
- Worker is now optionally
configurable with
graphile-config

(or.js
,.cjs
, etc) file - This enables a whole suite of new options and features, including being able to share your preset files across multiple projects!
- New plugin hooks added - get in touch if you need more!
- E.g. allows you to replace the task loading code entirely with your own implementation!
- Worker is now optionally
configurable with
- Support for loading tasks from nested folders

tasks/users/email/verify.js
will identify taskusers/email/verify
)
- (

- Support for loading both CommonJS and ESM files (including
.cjs
,.mjs
and.js
extensions)

- Any "compile-to-JS" language can be
- Tasks in non-JS languages (EXPERIMENTAL!)
- Enabled by the plugin system
- Any language your shell can execute: python, bash, rust, ...
- Place an executable file in the
tasks/
folder and ensure it's named with the task identifier (extensions ignored) - See Loading executable files in the documentation
abortSignal
: job cancellation (EXPERIMENTAL!)- Tasks can honour the
abortSignal
passed in via helpers to cancel asynchronous work ongracefulShutdown
- Can reduce waiting for the task to complete during a graceful shutdown; task
executor can listen for the
abortSignal
and decided whether to exit or continue
- Tasks can honour the
- TypeScript typing of tasks
- New
GraphileWorker.Tasks
global interface - Not recommended, but often requested!
- Types calls to
addJob()

- Adds
graphile_worker.jobs
view- A public interface to view details of jobs
- Stable across patch and minor versions
- DELIBERATELY excludes the
payload
field - Do not poll this, it will impact performance
- Do not do expensive filtering/ordering against this, it will impact performance
- New public
force_unlock_workers
database function- Unlocks all jobs from a list of crashed/terminated worker IDs
- Crontab: now supports
jobKey
andjobKeyMode
opts (thanks @spiffytech!) - Schema
- Checks that current schema in database isn't more up to date than the
current worker
- Won't be useful until future schema changes
- Trigger a graceful shutdown if a new Graphile Worker process migrates the database schema
- Checks that current schema in database isn't more up to date than the
current worker
- Events: add more detail to
cron:backfill
event - Tasks: now use
await import(...)
rather thanrequire(...)
, so ESM can be imported - Logging: changed format of task completion/failure logs to include attempts/max attempts and to reduce duplicate parenthesis
- Optimization: Replaces job announcement trigger with calls directly in
add_job
/add_jobs
to reduce queuing overhead
Fixes
- Fixes graceful shutdown (both manually via
.gracefulShutdown()
or.forcefulShutdown()
and via signal handling) - Signals: now releases signal handlers when shut down via the API
- Fixes bug where queuing 100 jobs in a single statement would only nudge a
single inactive worker
- Now as many workers as necessary and available will be nudged
v0.15.2-bridge.0
TL;DR: if you want to use Worker Pro to ease migration to v0.16.0, upgrade to this version if you're on v0.14.0 or higher, or v0.13.1-bridge.0 if you're on v0.13.0 or lower for Worker Pro support.
This release is a "bridge" release to make migration to v0.16.0 easier. Since v0.16.0 includes breaking database changes, no active workers should be running when the migrations happen, and once the migrations have happened older workers are no longer supported and their usage may lead to weird and undesirable behaviors.
Normally we'd recommend that you "scale to zero" before performing these kinds of migrations, to ensure that no older workers will be running against the DB at the same time; however this release adds support for the (proprietary) Worker Pro plugin which (when used consistently across your entire worker fleet) enables your workers to coordinate, triggering legacy workers to cleanly shut down (and waiting for them to do so) before migrating the database. The Worker Pro plugin also details the intent to upgrade, meaning if new legacy workers start up in the interrim, they will also not start looking for jobs since they know they will be out of date soon. As soon as all running tasks have finished processing (or a configurable timeout has elapsed) the migration will go ahead.
The Worker Pro plugin mentioned above is enabled by the addition of support for
graphile-config
, the standardized plugin and preset system for the entire
Graphile suite. Thanks to this integration, we've been able to add a
plugin/hooks system that you can use to customize the behavior of Worker
(including implementing some of the behaviors described in the previous
paragraph yourself, should you so desire).
This release also adds a startup check that will abort startup if the database already contains breaking migrations that are unsupported by the current worker version, and a significant number of back-ported fixes and new features that didn't require database migrations (including important fixes to the graceful shutdown system).
IMPORTANT: --watch
mode is no longer supported. We've removed this from
v0.16.0 (see the release notes for that version), you should use node --watch
or similar instead. This also removes fauxRequire
and all the problems that
that had.
IMPORTANT: Node versions before v20 and Postgres versions before v12 are no
longer supported. (Node v18 should work, but it segfaults when running the
tests which is likely a jest/node --experimental-vm-modules
issue which is
unlikely affect you at runtime.)
- Fixes graceful shutdown (both manually via
.gracefulShutdown()
or.forcefulShutdown()
and via signal handling) - Removes
maxContinguousErrors
setting which was poorly implemented and caused more issues than it solved - Tracks whether migrations are breaking or not, and:
- refuses to start if an unsupported breaking migration is present in the database
- gracefully shuts down if another worker performs a breaking migration
- NOTE: this is not sufficiently safe, it's just a backstop. If the migration breaks completing or failing of jobs then your worker will be unable to release in-progress tasks even if they're finished; and the worker performing the migrations will not wait for legacy workers to complete. You should shut down your workers before upgrading, or use Worker Pro to handle the situation automatically for you.
- Adds
graphile-config
support for presets and plugins - Adds more events and hooks
runTaskListOnce
now uses a WorkerPool internally (to better integrate with the gracefulShutdown logic)- Fix
WorkerPool.promise
to only resolve once everything is handled - EXPERIMENTAL; see v0.16.0 for documentation:
- Adds support for loading tasks from nested folders (e.g.
tasks/foo/bar/baz.js
will add support for a task with identifierfoo/bar/baz
) - Adds support for turning executable files into tasks (i.e. a task written in python, Rust, or bash)
- Adds support for loading TypeScript tasks directly (no need to compile to JS, but if you do the JS will have priority)
- You may see warnings like
WARNING: Failed to load task 'README.md' - no supported handlers found for path: '/path/to/tasks/README.md'
- you can ignore them (or you can move non-task files out of thetasks
folder) - Undocumented, experimental and untested preliminary support for cancellable
jobs via
AbortSignal
; upgrade to v0.16.0+ if you want to actually use this
- Adds support for loading tasks from nested folders (e.g.
- A huge number of internal changes
v0.15.1
Fixes issues with graceful worker shutdowns:
- Deprecates
workerPool.release()
in favour of (equivalent)workerPool.gracefulShutdown()
- Fixes
workerPool.gracefulShutdown()
to shut down gracefully (waiting for jobs to complete) - Adds
workerPool.forcefulShutdown()
to "fail" the running jobs (so they'll be re-attempted elsewhere) and force-release the pool - Fixes handling of signals:
- First termination signal triggers graceful shutdown
- Signal over next 5 seconds are ignored
- Second termination signal triggers forceful shutdown
- Signal over next 5 seconds are ignored
- Further termination signals are handled by Node (i.e. will likely instantly exit the process)
v0.15.0
Migration files are no longer read from filesystem (via fs
module); instead
they are stored as strings in JS to enable Graphile Worker to be bundled. The
files still exist and will continue to be distributed, so this should not be a
breaking change. Thanks to @timelf123 for this feature!
v0.14.0
THIS RELEASE INTRODUCES SIGNIFICANT CHANGES, in preparation for moving towards the 1.0 release. Please read these notes carefully.
IMPORTANT: this release is incompatible with previous releases - do not run earlier workers against this releases database schema or Bad Things will happen. You should shut down all workers before migrating to this version.
IMPORTANT: the initial migration, 000011
, in this release cannot run if
there are any locked jobs - it will throw a "division by zero" error in this
case. Please ensure all existing workers are shut down and any locked jobs
released before upgrading to this version.
IMPORTANT: migration 000011
renames the old jobs table, creates a new jobs
table with a slightly different format, copies the jobs across, and then deletes
the old jobs table. The jobs table itself is not a public interface - you should
use the documented SQL functions and TypeScript APIs only - but if you are
referencing the jobs table in a database function you may have a bad time.
IMPORTANT: priority
, attempts
and max_attempts
are all now smallint
,
so please make sure that your values fit into these ranges before starting the
migration process. (Really these values should never be larger than about 100
or smaller than about -100
anyway.)
Breaking changes
- BREAKING: Bump minimum Node version to 14 since 12.x is now end-of-life
- BREAKING: Bump minimum PG version to 12 for
generated always as (expression)
- BREAKING:
jobs.priority
,attempts
andmax_attempts
are nowint2
rather thanint4
(please ensure your values fit inint2
--32768 <= priority <= +32767
) - BREAKING: CronItem.pattern has been renamed to CronItem.match
- BREAKING: database error codes have been removed because we've moved to
CHECK
constraints
Changes to internals
- WARNING: the 'jobs' table no longer has
queue_name
andtask_identifier
columns; these have been replaced withjob_queue_id
andtask_id
which are bothint
s - WARNING: many of the "internal" SQL functions (
get_job
,fail_job
,complete_job
) have been moved to JS to allow for dynamic SQL generation for improved performance/flexibility - WARNING: most of the triggers have been removed (for performance reasons), so if you are inserting directly into the jobs table (don't do that, it's not a supported interface!) make sure you update your code to be compatible
Features
- New "batch jobs" feature for merging payloads with a
job_key
(see README) - Significantly improved 'large jobs table' performance (e.g. when a large queue is locked, or there's a lot of jobs queued for task identifiers your worker instance doesn't support, or a lot of failed jobs). Around 20x improvement in this 'worst case' performance for real user workloads.
- Added new (experimental) much faster
add_jobs
batch API. - Fix error handling of cron issues in 'run' method.
- CronItem.match can now accept either a pattern string or a matcher function
- Jobs that were locked more than 4 hours will be reattempted as before, however
they are slightly de-prioritised by virtue of having their
run_at
updated, giving interim jobs a chance to be executed (and lessening the impact of queue stalling through hanging tasks).
v0.13.1-bridge.0
TL;DR: if you want to use Worker Pro to ease migration to v0.16.0, upgrade to this version for Worker Pro support.
This release is a "bridge" release to make migration to v0.14.0 and v0.16.0 easier.

- Adds support for loading tasks from nested folders (e.g.
- A huge number of internal changes
v0.13.0
- Remove dependency on
pgcrypto
database extension (thanks @noinkling)- If you have a pre-existing installation and wish to uninstall
pgcrypto
you will need to do so manually. This can be done by runningDROP EXTENSION pgcrypto;
after updating to the latest schema.
- If you have a pre-existing installation and wish to uninstall
- The
jobs.queue_name
column no longer has a default value (this is only relevant to people inserting into the table directly, which is not recommended - use theadd_job
helper)
v0.12.2
- Fix issue when a connect error occurs whilst releasing worker (thanks @countcain)
v0.12.1
- Jobs with no queue are now released during graceful shutdown (thanks @olexiyb)
v0.12.0
- Run shutdown actions in reverse order (rather than parallel) - more stable release
- When an error occurs with the new job listener, reconnection attempts now follow an exponential back-off pattern
- Allow using Node.js time rather than PostgreSQL time (particularly useful for tests)
- Refactoring of some cron internals
- Add
noPreparedStatements
to the docs
v0.11.4
- Fixes bug in crontab day-of-week check
- Exposes
parseCronItem
helper
v0.11.3
- Restores
Logger
export accidentally removed in v0.11.0
v0.11.2
- Added support for wider range of
@types/pg
dependency
v0.11.1
- Handles unexpected errors whilst PostgreSQL client is idle
v0.11.0
- Export
getCronItems
so library-mode users can watch the crontab file - Replace
Logger
with new@graphile/logger
module
v0.10.0
- No longer exit on SIGPIPE (Node will swallow this error code)
- Fix issue with error handling on PostgreSQL restart or
pg_terminate_backend
- Fix a potential unhandled promise rejection
v0.9.0
- New (experimental) "cron" functionality for regularly scheduled jobs
- Replace jobs ordering index for improved performance (thanks @ben-pr-p)
- NOTE: this migration might take a moment if you have a large jobs table
- New events system lets you monitor what's going on inside Graphile Worker
- New
job_key_mode
setting; see README for full details, but summary:- defaults to
replace
(existing behavior, i.e. debouncing) - if set to
preserve_run_at
it will preserverun_at
which effectively changes it from debouncing to throttling - if set to
unsafe_dedupe
it will not update the attributes when an existing job with that job key exists, even if that job is already running
- defaults to
remove_job
now prevents locked jobs from running again on error (and removes their key)- Dependency updates
v0.8.1
- Fix issue with cyclic requires in watch mode
v0.8.0
- Track revision count for jobs (thanks @lukeramsden)
- "Forbidden flags" feature for rate limiting (thanks @ben-pr-p)

- Add support for
PG*
PostgreSQL envvars
v0.7.2
- Add
--no-prepared-statements
flag to allow disabling of prepared statements for pgBouncer compatibility. - Fix issue in watch mode where files
require()
d from inside a task are cached permanently.
(v0.7.0 and v0.7.1 had issues with the experimental watch mode enhancements, so
were never upgraded to @latest
.)
v0.6.1
- Official Docker image (thanks @madflow)
v0.6.0
- Use target es2018 for TypeScript (Node v10 supports everything we need) (thanks @keepitsimple)
- When task promise is rejected with non-Error, use a fallback (thanks @parker-torii)
- Support
[email protected]
and hence Node v14 (thanks @purge) - Fix mistake in README
- General maintenance
v0.5.0
New "Administrative functions", ability to rename graphile_worker
schema, and
significant overhaul of the codebase in preparation for going to v1.0.
v0.5.0 improvements:
- Added "Administrative functions" to complete, reschedule or fail jobs in bulk (good for UIs)
- Added
noHandleSignals
option to disable our signal handling (if you enable this, make sure you use your own signal handling!) - Ability to rename
graphile_worker
schema - Added
cosmiconfig
for configuration (very few options support this currently) - Decrease already negligible chance of worker ID collision (use
crypto.randomBytes()
rather thanMath.random()
)
v0.5.0 breaking changes:
CLI users: no breaking changes.
Library users: none of the documented (in the README) APIs are affected,
except runTaskListOnce
and some tiny tweaks to TypeScript types.
The ability to override the SQL schema means that everything in the codebase needs to know this setting. To achieve this:
- all major APIs now accept
options
as a configuration parameter - where this was optional before it is now required
- where options was not the first argument, it has been moved to the first argument (for consistency)
As such the following APIs (most of which are internal) have been changed:
getTasks(taskPath, watch, logger)
->getTasks(options, taskPath, watch)
runTaskList(tasks, pgPool, options?)
->runTaskList(options, tasks, pgPool)
runTaskListOnce(tasks, client, options?)
->runTaskList(options, tasks, client)
migrate(client)
->migrate(options, client)
makeAddJob(withPgClient)
->makeAddJob(options, withPgClient)
makeJobHelpers(job, { withPgClient }, baseLogger)
->makeJobHelpers(options, job, { withPgClient, logger? })
makeNewWorker(tasks, withPgClient, options, continuous)
->makeNewWorker(options, tasks, withPgClient, continuous)
Also if you're a TypeScript user: we've renamed WorkerSharedOptions
to
SharedOptions
and added a new WorkerSharedOptions
. This is particularly
relevant if you're using the WorkerUtils
class. We've also tweaked what
options are available on each of these, but this is unlikely to affect you
negatively.
v0.4.0
Performance improvements and ability to efficiently queue jobs from JS.
BREAKING CHANGES:
- TypeScript:
- the ID of a job is a
string
(databasebigint
), we previously incorrectly stated it was anumber
. Helpers
was renamed toJobHelpers
TaskOptions
was renamed toTaskSpec
- the ID of a job is a
queue_name
is now nullable (leave it null for maximum parallel performance)- when a job is modified using a
job_key
, thequeue_name
attribute is now reset like the other attributes
WARNINGS:
- The database schema has changed; your code should not depend on the database
schema, only on the public interfaces (
add_job
,remove_job
, etc), so this shouldn't be an issue.
New features:
- Significantly enhanced performance
- Changes database schema such that a job_queue record is only added/checked when necessary
- Uses prepared statements
- Can override the PostgreSQL pool size on the CLI (via
--max-pool-size
)
- Dedicated API for queueing jobs from JavaScript/TypeScript (
makeWorkerUtils
/quickAddJob
; @mrmurphy, @benjie #60) --once
now respects--jobs
, so it can run jobs in paralleljobKey
is now available via TypeScript API (@tim-field, #78)
Other:
- Overhauled the
perfTest
script - Upgraded dependencies
v0.3.0-rc.0
v0.3.0-rc.0 was never released as v0.3.0 because we jumped to v0.4.0 too soon.
New features:
job_key
enables existing jobs to be updated and deleted; can also be used for de-duplication (@gregplaysguitar, @benjie #63)
Fixes:
- Fixes
runner.stop()
(@MarkCBall, #66)
v0.2.0
BREAKING CHANGES:
- The
debug
task helper has been replaced with alogger
helper which is aLogger
instance (see README) - The
-1
shortcut for "run once" never worked; it has been removed - Unrecognised command-line arguments will now cause an error to be thrown
New features:
- Added
--schema-only
CLI flag for installing/updating the schema (running migrations) only - It's now possible to override how logs are output by supplying a
logFactory
(see README) query
helper reduces boilerplate
Fixes:
- We never needed
uuid-ossp
so we've removed the requirement (you may want to remove the extension from your DB manually)
v0.1.0
- Add database 'error' handler to avoid crashes (@madflow #26)
DATABASE_URL
can now be used in place ofconnectionString
(@madflow, @benjie#20#27)- Improve documentation (@madflow, @archlemon, @benjie #11 #18 #31 #33)
- Improve testing (@madflow #19 #30)
v0.1.0-alpha.0
Now usable as a library as well as a CLI.
Changes:
- Renamed a number of internals
start
->runTaskList
runAllJobs
->runTaskListOnce
workerCount
->concurrency
- Add an easy way to run as a library (
run
andrunOnce
methods) - CLI code reduced as it uses new library code
- Implemented linting
- Exported more methods
v0.0.1-alpha.7
- Add missing
tslib
dependency
