issue: #45841
- CPP log make the multi log line in one debug, remove the "\n\t".
- remove some log that make no sense.
- slow down some log like ChannelDistManager.
<!-- This is an auto-generated comment: release notes by coderabbit.ai

- Core invariant: logging is purely observational — this PR only
reduces, consolidates, or reformats diagnostic output (removing
per-item/noise logs, consolidating batched logs, and converting
multi-line log strings) while preserving all control flow, return
values, and state mutations across affected code paths.
- Removed / simplified logic: deleted low-value per-operation debug/info
logs (e.g., ListIndexes, GetRecoveryInfo, GcConfirm,
push-to-reorder-buffer, several streaming/wal/debug traces), replaced
per-item inline logs with single batched deferred logs in
querynodev2/delegator (logExcludeInfo) and CleanInvalid, changed C++
PlanNode ToString() multi-line output to compact single-line bracketed
format (removed "\n\t"), and added thresholded interceptor logging
(InterceptorMetrics.ShouldBeLogged) and message-type-driven log levels
to avoid verbose entries.
- Why this does NOT cause data loss or behavioral regression: no
function signatures, branching, state updates, persistence calls, or
return values were changed — examples: ListIndexes still returns the
same Status/IndexInfos; GcConfirm still constructs and returns
resp.GetGcFinished(); Insert and CleanInvalid still perform the same
insert/removal operations (only their per-item logging was aggregated);
PlanNode ToString changes only affect emitted debug strings. All error
handling and control flow paths remain intact.
- Enhancement intent: reduce log volume and improve signal-to-noise for
debugging by removing redundant, noisy logs and emitting concise,
rate-/threshold-limited summaries while preserving necessary diagnostics
and original program behavior.

- 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(ReplicateMsg types, ReplicateID-based guards and flags) is obsolete —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.

Support crate analyzer with file resource info, and return used file
resource ids when validate analyzer.
Save the related resource ids in collection schema.
relate: https://github.com/milvus-io/milvus/issues/43687
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
- Core invariant: analyzer file-resource resolution is deterministic and
traceable by threading a FileResourcePathHelper (collecting used
resource IDs in a HashSet) through all tokenizer/analyzer construction
and validation paths; validate_analyzer(params, extra_info) returns the
collected Vec<i64) which is propagated through C/Rust/Go layers to
callers (CValidateResult → RustResult::from_vec_i64 → Go []int64 →
querypb.ValidateAnalyzerResponse.ResourceIds →
CollectionSchema.FileResourceIds).
- Logic removed/simplified: ad‑hoc, scattered resource-path lookups and
per-filter file helpers (e.g., read_synonyms_file and other inline
file-reading logic) were consolidated into ResourceInfo +
FileResourcePathHelper and a centralized get_resource_path(helper, ...)
API; filter/tokenizer builder APIs now accept &mut
FileResourcePathHelper so all file path resolution and ID collection use
the same path and bookkeeping logic (redundant duplicated lookups
removed).
- Why no data loss or behavior regression: changes are additive and
default-preserving — existing call sites pass extra_info = "" so
analyzer creation/validation behavior and error paths remain unchanged;
new Collection.FileResourceIds is populated from resp.ResourceIds in
validateSchema and round‑tripped through marshal/unmarshal
(model.Collection ↔ schemapb.CollectionSchema) so schema persistence
uses the new list without overwriting other schema fields; proto change
adds a repeated field (resource_ids) which is wire‑compatible (older
clients ignore extra field). Concrete code paths: analyzer creation
still uses create_analyzer (now with extra_info ""), tokenizer
validation still returns errors as before but now also returns IDs via
CValidateResult/RustResult, and rootcoord.validateSchema assigns
resp.ResourceIds → schema.FileResourceIds.
- New capability added: end‑to‑end discovery, return, and persistence of
file resource IDs used by analyzers — validate flows now return resource
IDs and the system stores them in collection schema (affects tantivy
analyzer binding, canalyzer C bindings, internal/util analyzer APIs,
querynode ValidateAnalyzer response, and rootcoord/create_collection
flow).

1. Use an internal health checker to monitor the cluster's health state,
storing the latest state on the coordinator node. The CheckHealth
request retrieves the cluster's health from this latest state on the
proxy sides, which enhances cluster stability.
2. Each health check will assess all collections and channels, with
detailed failure messages temporarily saved in the latest state.
3. Use CheckHealth request instead of the heavy GetMetrics request on
the querynode and datanode
