Update a distributed job

Updates a distributed job.

Checked 2026-09-28

This method is not served on the public API. api.sylphx.com does not route this call: its backend is not deployed behind the public API, or does not implement the call. This page documents the contract. It is kept out of the sidebar and of search engines.

Updates a distributed job. Runs already started keep the generation they pinned.

Path PATCH https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/distributed_jobs/distributed-job
Scope workflows:write
Effect write — a successful call changes state.
Collection distributed_jobs
Query update_mask, allow_missing, validate_only
Operation answers with an Operation; the result is DistributedJob

#Request

Field	Type	What it is
`distributed_job`	`DistributedJob`	The distributed job to update; `name` identifies it. Required.
`update_mask`	`field_mask`	The fields to write; unset writes every populated field.
`allow_missing`	`bool`	Create the distributed job when it does not exist (declarative upsert).
`validate_only`	`bool`	Validate and return the result without writing anything.

#DistributedJob

Field	Type	What it is
`name`	`string`	`orgs/{org}/projects/{project}/envs/{env}/distributed_jobs/{distributed_job}`.
`meta`	`ResourceMeta`	Resource metadata.
`spec`	`DistributedJobSpec`	Desired state. Required.

#ResourceMeta

Field	Type	What it is
`labels`	`map<string, string>`	Caller-writable, indexed labels (AIP-122 label rules).
`annotations`	`map<string, string>`	Caller-writable, unindexed annotations.
`display_name`	`string`	Caller-writable human-readable name.

#DistributedJobSpec

Field	Type	What it is
`worker`	`JobSpec`	The worker container: its image, command, env and instance type. `timeout` is the longest one worker lives, so the pool turns over; `max_retries` and `concurrency` do not apply. Required.
`worker_class`	`WorkerClass`	Price and preemption class; default scavenger. One of `scavenger`, `standard`.
`scale`	`WorkerScale`	Elastic bounds of the worker pool.
`scratch_gib`	`int32`	Local scratch disk at `/scratch` per worker, GiB; 0 is none.
`shard_count`	`int64`	A run that brings no shards of its own gets this many index-only shards.
`shard_timeout`	`duration`	The longest one lease may live without the shard ending; default 30m.
`shard_retries`	`int32`	Attempts a shard gets after a failure; a preemption is not one. Default 3.
`max_failed_shards`	`int64`	Failed shards the run tolerates before it fails; default 0.
`run_timeout`	`duration`	The whole run's deadline; default 48h.
`checkpoint_uri`	`string`	`data://<bucket>/<prefix>/`: checkpoints go under `<run>/<shard>/`.
`output_uri`	`string`	`data://<bucket>/<prefix>/`: outputs go under `<run>/<shard>/`.

#JobSpec

Field	Type	What it is
`service`	`string`	The Hosting Service whose env and Secret bindings every run takes, and whose live Release image it runs unless `image` or `build` names another, so a Job never runs code the environment does not serve. Required.
`image`	`string`	A digest-pinned image from this org's Artifacts, in place of the service's image. Exclusive with `build`.
`command`	`string[]`	The entrypoint; empty keeps the image's.
`args`	`string[]`	Arguments; a run may replace them.
`env`	`map<string, string>`	Environment overrides on top of the service's env and Secret bindings.
`instance_type`	`string`	A Hosting instance type; default `standard`.
`timeout`	`duration`	One attempt's deadline, 10s to 24h; default 1h.
`max_retries`	`int32`	Re-runs after a non-zero exit, 0 to 10; backoff 30s doubling.
`concurrency`	`JobConcurrency`	What a start does while a run is active; default forbid. One of `forbid`, `queue`, `allow`.
`build`	`string`	A build the project declares: its latest built image, in place of the service's; the image needs no running service of its own. Exclusive with `image`.

#WorkerScale

Field	Type	What it is
`min_workers`	`int32`	Workers kept while shards remain; default 1.
`max_workers`	`int32`	The most workers at once; the Cell and the org quota cap it too. Default 1.

#Response

Field	Type	What it is
`name`	`string`	`{parent-of-target}/operations/{operation}`.
`target`	`string`	The name of the Resource being changed.
`target_generation`	`int64`	The generation this Operation waits for.
`verb`	`OperationVerb`	What the Operation does. One of `create`, `update`, `delete`, `custom`.
`custom_verb`	`string`	The custom method verb when `verb` is CUSTOM, for example `revoke`.
`done`	`bool`	Whether the Operation has finished.
`create_time`	`timestamp`	When the Operation started.
`end_time`	`timestamp`	When the Operation finished.
`response`	`any`	The settled Resource (or Empty for a delete). One of the `result` group.
`error`	`ProblemDetails`	The failure, as the one error body. One of the `result` group.
`progress`	`OperationProgress`	Progress while not `done`.

#ProblemDetails

Field	Type	What it is
`type`	`string`	`https://sylphx.com/docs/errors/<code in kebab-case>`.
`title`	`string`	A short customer-safe summary of the problem class.
`status`	`int32`	The HTTP status, fixed by `grpc_status`.
`detail`	`string`	A customer-safe explanation of this occurrence. Never contains SQL, stack traces, internal hostnames, or another tenant's data.
`instance`	`string`	The request id (`Sylphx-Request-Id`).
`code`	`string`	The stable UPPER_SNAKE code, one of ErrorCode without its prefix.
`grpc_status`	`string`	One of the 16 canonical gRPC status names, for example `ABORTED`.
`retryable`	`bool`	Whether the same request may be retried.
`effect`	`ErrorEffect`	What the failed call committed. One of `none`, `applied`, `unknown`.
`retry_after_ms`	`int64`	How long to wait before retrying, when the server knows.
`details`	`any[]`	Typed details such as PreconditionFailure or EntitlementDenial.

#OperationProgress

Field	Type	What it is
`percent`	`int32`	Percent complete, when the controller can tell.
`message`	`string`	A customer-safe progress message.
`conditions`	`Condition[]`	The target's conditions when this progress was read.

#Condition

Field	Type	What it is
`type`	`string`	The condition type, for example `Ready`.
`status`	`ConditionStatus`	Whether the condition holds. One of `true`, `false`, `unknown`.
`observed_generation`	`int64`	The generation this observation was made against.
`reason`	`string`	A machine-readable UpperCamelCase reason.
`message`	`string`	A customer-safe human-readable message.
`severity`	`Severity`	How severe a FALSE condition is. One of `info`, `warning`, `error`.
