Distributed Locks
ACQUIRE_LOCK / RELEASE_LOCK for serialising sections of a workflow across concurrent runs.
Distributed Locks
Lock components let you serialise critical sections of a workflow across concurrent runs. When two runs hit the same lockId, only one proceeds; the other waits (or times out).
Lock state is held with a configurable TTL — if execution is interrupted mid-section, the lock auto-releases when the TTL expires, so workflows never get permanently stuck.
ACQUIRE_LOCK
ACQUIRE_LOCK Workflow
Reserves exclusive access to a lock ID. Blocks until the lock is acquired or ttl seconds elapse.
Config
| Field | Type | Description |
|---|---|---|
ttl | number (1–15) | Maximum seconds to wait for the lock and maximum hold time once acquired |
Inputs
| Field | Type | Description |
|---|---|---|
lockId | string | Logical lock name. Two runs with the same lockId will serialise |
Outputs
| Field | Type | Description |
|---|---|---|
success | boolean | Always true when the call returns successfully — failure throws 403 Timed out |
RELEASE_LOCK
RELEASE_LOCK Workflow
Releases a lock acquired earlier in the same workflow. Always pair ACQUIRE_LOCK with RELEASE_LOCK to free the resource immediately rather than waiting for the TTL.
Inputs
| Field | Type | Description |
|---|---|---|
lockId | string | Lock to release |
Outputs
| Field | Type | Description |
|---|---|---|
success | boolean | true when the release completed |

RETURNLocks are workspace-wide, not workflow-wide. The same lockId from two different workflows in the same workspace will serialise — useful for protecting a shared on-chain account.
Variables & Object Manipulation
Workflow-scoped array variables (CREATE / APPEND / GET) plus object utilities (MERGE_ARRAYS, GET_OBJECT_VALUE, FIND_ARRAY_OBJECT).
