From 171dbdb4f36496cebf0e9721c93401e0075c0929 Mon Sep 17 00:00:00 2001 From: chrislu Date: Fri, 12 Sep 2025 00:46:18 -0700 Subject: [PATCH] Phase 4: Integrate offset management with SMQ broker components - Add SW_COLUMN_NAME_OFFSET field to parquet storage for offset persistence - Create BrokerOffsetManager for coordinating offset assignment across partitions - Integrate offset manager into MessageQueueBroker initialization - Add PublishWithOffset method to LocalPartition for offset-aware publishing - Update broker publish flow to assign offsets during message processing - Create offset-aware subscription handlers for consume operations - Add comprehensive broker offset integration tests - Support both single and batch offset assignment - Implement offset-based subscription creation and management - Add partition offset information and metrics APIs Key TODOs and Assumptions: - TODO: Replace in-memory storage with SQL-based persistence in Phase 5 - TODO: Integrate LogBuffer to natively handle offset assignment - TODO: Add proper partition field access in subscription requests - ASSUMPTION: LogEntry.Offset field populated by broker during publishing - ASSUMPTION: Offset information preserved through parquet storage integration - ASSUMPTION: BrokerOffsetManager handles all partition offset coordination Tests show basic functionality working, some integration issues expected until Phase 5 SQL storage backend is implemented. --- weed/mq/broker/broker_grpc_pub.go | 15 +- weed/mq/broker/broker_grpc_sub_offset.go | 179 +++++++++
