kvrpcpb: report noisy resource groups in HealthFeedback (#1543) TiKV already knows which resource groups it blames for its own overload -- `ResourceGroupManager` keeps the set in `noisy_groups` and refreshes it on the control tick -- but the only way that verdict reaches a client today is the `|noisy_tenant` suffix on a `ServerIsBusy` reason, which arrives only when a request from that group is actually rejected. Every group has to be rejected once to be discovered, and the client has no way to learn that a group stopped being noisy. Carry the set on `HealthFeedback` instead, which is already attached to batch responses on a timer, so a client learns the whole set from any response. `noisy_groups` is a message rather than a bare repeated field so that a store which does not report the set at all stays distinguishable from one reporting an empty set: the former leaves the field unset, the latter sends an empty `names`, and only the latter licenses a client to clear what it knew.

feat(kvproto): add scan and lock request

*: add txn protocol version declaration (#1534) Introduce a protocol version registry and the request declaration that lets a client tell the server which transaction protocol semantics it implements, so that requests from callers which cannot handle a feature can be rejected consistently instead of being served with best effort. - kvrpcpb: add the TxnProtocolVersion enum and Context.txn_protocol_version (tag 39). Version numbers accumulate monotonically: 0 is legacy, 1 means the client handles the structured incompatibility error, and 2 covers the shared lock protocol. A missing field and an explicit 0 both mean legacy. Also extend RequestOrigin with TiCDC, BR and TiFlash and document that the origin is client-provided auditing metadata, not an authorization decision. - errorpb: add IncompatibleRequest (reason, message, provided/min/max compatible version) and Error.incompatible_request (tag 23). The bounds are inclusive and the two error fields stay independent message fields. A rejection of a request that declared no version also sets ServerIsBusy.reason to the fixed "txn_protocol_incompatible" fallback for legacy clients; a declared non-zero version gets no fallback. - metapb: add TxnProtocolVersionRange and Store.txn_protocol_version_range (tag 14). The message field keeps its presence so that an absent range stays distinguishable from an explicit [0, 0]. Signed-off-by: zyguan <zhongyangguan@gmail.com>

feat(pdpb): add WatchGCStates API (#1528) Add a server-streaming API for observing effective GC state changes. Represent updates as ordered upsert and removal events so clients can maintain a materialized per-keyspace view and reload it after reconnecting. Keep GC barriers internal to PD. The stream omits barrier details and barrier-only updates while still reporting changes to the resulting effective safe points.

coprocessor: add batch task merge and serial execution controls (#1497) Add explicit controls for batched coprocessor task results and execution: - Request.allow_batch_task_data_merge: the client declares it can consume a response whose batched tasks' results are merged into the single result carried by the response's data (e.g. the per-region sampling results of a batched analyze request). - StoreBatchTaskResponse.data_merged_into_response: the store acknowledges a merged task; the batch response carries no data of its own but still acknowledges the task and carries its execution details. - Request.execute_batch_tasks_serially: the client asks the store to run the primary task and all batched tasks one at a time, limiting within-request concurrency without guaranteeing execution order. A store that does not support merging keeps responding per task, and a client that does not set the merge request field keeps receiving per-task responses, so either side can upgrade first. Stores that do not support serial execution ignore the new request field and retain existing behavior. Signed-off-by: 0xPoe <poe.liu@pm.me>

proto: add paging_size_bytes to coprocessor.Request (#1448) Add a new uint64 field `paging_size_bytes` (field 17) to the coprocessor Request message. When set, TiKV will stop scanning when accumulated scanned bytes reach this limit, enabling byte-budget paging for finer-grained Resource Control. Note: rebased onto upstream master where field 16 is now taken by max_keys_read (#1450), so paging_size_bytes was bumped from field 16 to field 17. Signed-off-by: JmPotato <github@ipotato.me>

externalworkloadpb: add external workload controller proto (#1468) * externalworkloadpb: add external workload controller proto Add proto/externalworkloadpb.proto defining the ExternalWorkloadController gRPC service that an external controller exposes to TiDB instances. Under the Starter deploy mode TiDB calls into it to register and recycle background workloads (GC, distributed background subtasks, TTL, auto-analyze, remote queries) so the controller can run them on dedicated TiDB instances and scale those instances on demand. Generated Go lands in pkg/externalworkloadpb; the new file is registered in scripts/proto.lock. * externalworkloadpb: clarify TTL recycle watermark * externalworkloadpb: pair bg task exec assignments * externalworkloadpb: clarify workload timing comments
