Add comprehensive doc comments to BatchEnqueueContext, the Broker
interface method, and the RDB implementation explaining that the batch
uses a Redis pipeline (not MULTI/EXEC), so partial success is possible
and individual Lua scripts are atomic but the batch is not.
Fix a bug where Script.Run inside a pipeline only sends EVALSHA without
the automatic EVAL fallback that non-pipeline calls get. On a fresh
Redis (or after SCRIPT FLUSH), this caused NOSCRIPT errors for every
pipeline-batched script invocation. The fix preloads the required Lua
scripts before building the pipeline.
Also roll back the in-memory queuesPublished cache when the pipeline
fails, preventing stale entries from suppressing future SADD calls.
BatchEnqueueContext had a time comparison bug where `now` was captured
before the loop but `processAt` was set to time.Now() inside
composeOptions during each iteration, causing all immediate tasks to be
incorrectly classified as scheduled and rejected.
Fix: move `now` capture inside the loop, after composeOptions.
Additionally, extend BatchEnqueueContext to support scheduled tasks in
the same pipeline. Tasks with a future ProcessAt are now routed to
scheduleCmd (ZADD to scheduled set) instead of being rejected. Only
unique and group tasks remain unsupported.
Changes:
- Add BatchEnqueueItem type pairing TaskMessage with optional ProcessAt
- Update Broker interface, RDB, and testbroker to use BatchEnqueueItem
- Route immediate tasks to enqueueCmd, scheduled tasks to scheduleCmd
- Return correct TaskState (Pending vs Scheduled) in results
- Add tests for immediate, scheduled, and mixed batch scenarios
Adds BatchEnqueue to the Broker interface and RDB implementation that
sends multiple enqueueCmd Lua script invocations in a single Redis
pipeline round-trip. Also adds BatchEnqueueContext to the Client as
the public API, returning per-task results for partial-success handling.
