issue: https://github.com/milvus-io/milvus/issues/44123 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> - Core invariant: legacy in-cluster CDC/replication plumbing (ReplicateMsg types, ReplicateID-based guards and flags) is obsolete — the system relies on standard msgstream positions, subPos/end-ts semantics and timetick ordering as the single source of truth for message ordering and skipping, so replication-specific channels/types/guards can be removed safely. - Removed/simplified logic (what and why): removed replication feature flags and params (ReplicateMsgChannel, TTMsgEnabled, CollectionReplicateEnable), ReplicateMsg type and its tests, ReplicateID constants/helpers and MergeProperties hooks, ReplicateConfig and its propagation (streamPipeline, StreamConfig, dispatcher, target), replicate-aware dispatcher/pipeline branches, and replicate-mode pre-checks/timestamp-allocation in proxy tasks — these implemented a redundant alternate “replicate-mode” pathway that duplicated position/end-ts and timetick logic. - Why this does NOT cause data loss or regression (concrete code paths): no persistence or core write paths were removed — proxy PreExecute flows (internal/proxy/task_*.go) still perform the same schema/ID/size validations and then follow the normal non-replicate execution path; dispatcher and pipeline continue to use position/subPos and pullback/end-ts in Seek/grouping (pkg/mq/msgdispatcher/dispatcher.go, internal/util/pipeline/stream_pipeline.go), so skipping and ordering behavior remains unchanged; timetick emission in rootcoord (sendMinDdlTsAsTt) is now ungated (no silent suppression), preserving or increasing timetick delivery rather than removing it. - PR type and net effect: Enhancement/Refactor — removes deprecated replication API surface (types, helpers, config, tests) and replication branches, simplifies public APIs and constructor signatures, and reduces surface area for future maintenance while keeping DML/DDL persistence, ordering, and seek semantics intact. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: bigsheeper <yihao.dai@zilliz.com>
