special issue for eric

Edits made:

  • packages/core/src/v3/schemas/common.ts

    • Added optional concurrencyKey to both TaskRunExecution and TaskRunContext:
      • concurrencyKey?: string on the top-level of both objects.
  • internal-packages/run-engine/src/engine/systems/runAttemptSystem.ts

    • In resolveTaskRunContext:
      • Included concurrencyKey: true in the Prisma select.
      • Returned concurrencyKey: run.concurrencyKey ?? undefined at the top-level of the context.
    • In startRunAttempt (where the execution payload is built):
      • Included concurrencyKey: true in the Prisma select.
      • Added concurrencyKey: updatedRun.concurrencyKey ?? undefined to the top-level of the execution payload.

Why this fixes it:

  • The worker process parses TaskRunContext directly from the execution payload. With the schema updates and engine population, ctx.concurrencyKey will now be available in the task’s run function as requested.

Notes on validation:

  • There’s already a log in the managed worker that prints the received execution payload. That log will now include concurrencyKey, allowing you to verify it quickly.

  • Lints on modified files show no errors.

  • Added ctx.concurrencyKey support:

    • Schemas: Added concurrencyKey?: string to TaskRunExecution and TaskRunContext in packages/core/src/v3/schemas/common.ts.
    • Engine: Selected and populated concurrencyKey in resolveTaskRunContext and the execution payload in startRunAttempt within internal-packages/run-engine/src/engine/systems/runAttemptSystem.ts.
    • You can now access it via ctx.concurrencyKey inside task run.

Walkthrough

The changes introduce support for a concurrencyKey property throughout the task run execution flow. In the engine system, the concurrencyKey is now fetched from the database and included in the internal context and execution objects when resolving or starting a run attempt. Additionally, the core schema definitions for TaskRunExecution and TaskRunContext are updated to include an optional concurrencyKey property. No other logic, validation, or control flow is modified, and no public API signatures are altered.

337-338: Add basic validation guardrails for the new concurrencyKey.

Because this key is used for queue–sharding logic, leaving it completely unrestricted invites accidental or maliciously long / malformed strings that could bloat DB rows, cache keys, or metric labels.
Recommend capping length (e.g. 256 chars) and/or restricting to safe characters.

-  concurrencyKey: z.string().optional(),
+  concurrencyKey: z.string().max(256).optional(),

Apply the same guard to both TaskRunExecution and TaskRunContext for consistency.

Timestamp: 2025-07-12T18:06:04.133Z
Learning: In apps/webapp/app/services/runsRepository.server.ts, the in-memory status filtering after fetching runs from Prisma is intentionally used as a workaround for ClickHouse data delays. This approach is acceptable because the result set is limited to a maximum of 100 runs due to pagination, making the performance impact negligible.

184-184: Ensure the DB column concurrencyKey is indexed.

Both resolveTaskRunContext and startRunAttempt now fetch concurrencyKey.
If future logic filters or sorts on this field, missing indexes will trigger full-table scans on taskRun, which is usually large.

Please confirm that the migration adding the column also created an index, or add one proactively.

Also applies to: 401-401


252-252: LGTM – value is correctly surfaced to the worker payload.

The property is forwarded in both the lightweight context and the full execution envelope, keeping backwards compatibility.

Also applies to: 539-539
