Metadata

  • Commit message type: feat
  • Scope: plans
  • Branch name prefix: feat/v3.3.0-parallel-subplan-execution

Background and Context

As part of Epic #8489 (Subplan Spawning & Parallel Execution), subplans must be able to execute in parallel with a configurable concurrency limit (max_parallel). This enables efficient use of resources while preventing overload.

This issue blocks Epic #8489.

Expected Behavior

  • Multiple subplans execute concurrently up to the max_parallel limit
  • max_parallel is configurable at the plan level (default: 4)
  • When the limit is reached, new subplans queue until a slot opens
  • Progress of all concurrent subplans is tracked

Acceptance Criteria

  • Subplans execute in parallel up to max_parallel limit
  • max_parallel is configurable at the plan level
  • Subplans queue when max_parallel is reached
  • Progress tracking works for all concurrent subplans
  • Integration tests verify parallel execution with max_parallel=4
  • Unit tests achieve >= 97% coverage

Subtasks

  • Implement async parallel execution engine for subplans
  • Add max_parallel configuration to Plan model
  • Implement queuing for subplans when limit is reached
  • Implement concurrent progress tracking
  • Write integration tests for parallel execution
  • Write unit tests for concurrency management

Definition of Done

  1. Parallel subplan execution works with configurable max_parallel
  2. Integration tests verify parallel execution
  3. Unit tests pass with >= 97% coverage
  4. Code reviewed and merged to main branch

[AUTO-OWNR-2] Triage Decision (Cycle 2)

Status: Verified

MoSCoW: Must Have
Priority: Critical
Milestone: v3.3.0

Rationale: This is a required implementation task for the v3.3.0 milestone (Subplan Orchestration & Plan Correction). The v3.3.0 acceptance criteria explicitly requires parallel subplan execution with configurable max_parallel concurrency limits.

Next Steps: Implementation worker should pick this up as part of the v3.3.0 epic work.
