## Summary ### Why? Vitess needs a stable vindex that is not the Kafka-style partition key. Isolation has to be an explicit tenant column, with identity carried on publish and consume so two tenants sharing a partition key cannot collide. ### What? - Prefix every queue table and store query with tenant; set queue_offsets PK to (tenant, topic, partition_key, consumer_group). - Use typed (tenant, partitionKey) identities in consumers, gates, and MySQL workers; stop workers when lease discovery cannot confirm ownership. - Require tenant on publish.Message and validate payload queue against message tenant in pipeline controllers (the publish signature change is not compilable without those call sites). - Add ParseRequiredTenants and wire Stovepipe ingest to the configured tenant list so NewIngestController still builds. - Require tenant xor all-tenants on MQ admin list commands; message inspect/delete/requeue take the full (tenant, topic, partition, id) identity. - Comment ascii/ascii_bin vs utf8mb4/utf8mb4_bin on every queue table, with the full encoding note on queue_messages. ## Test Plan ✅ `go test` on mysql, publish, consumer, messagequeue identity, service/messagequeue, and start controller Rebased onto current `main` after RFC #693 merged. ## Stack - ~~[#693](#693) RFC: per-tenant sharding for the MySQL message queue~~ (merged) - [#694](#694) Shard MySQL queues by tenant identity - [#695](#695) Wire MQ_TENANTS through services and tests - [#696](#696) Add Vitess vschema and two-shard vtcombo suite --------- Co-authored-by: Cursor <cursoragent@cursor.com>
## Summary ### Why? The MySQL subscriber only discovers partitions for configured tenants. Service processes and compose stacks must pass the same list they already use as queue names, or Subscribe fails at startup and tests talk to an unsharded process. ### What? - Parse MQ_TENANTS in gateway, orchestrator, and runway wiring and reject configs whose queue names do not match. - Set MQ_TENANTS in service compose files, e2e harnesses, and SubmitQueue integration suites. ## Test Plan ✅ `go test` TestValidateConfiguredQueueTenants, TestValidateProfileQueueTenants, TestValidateMergeQueueTenants, and service/messagequeue Co-authored-by: Cursor <cursoragent@cursor.com>
