fix: add privilege_ext to GetPartitionStatisticsRequest for RBAC (#654) Backport of #652 to 3.0. GetPartitionStatisticsRequest was missing the privilege_ext_obj annotation that its sibling GetCollectionStatisticsRequest carries. milvus's PrivilegeInterceptor treats a request with no privilege_ext annotation as "no permission required" and lets it through (fail-open), so an authenticated but unauthorized account could read any collection's partition statistics, bypassing the intended PrivilegeGetStatistics check. This mirrors the sibling annotation (object_type Collection, PrivilegeGetStatistics, object_name_index 3). Note: this is a permission tightening. Accounts that previously called GetPartitionStatistics without PrivilegeGetStatistics will be denied once milvus core bumps this proto.

fix: add privilege_ext to GetPartitionStatisticsRequest for RBAC (#652) GetPartitionStatisticsRequest was missing the privilege_ext_obj annotation that its sibling GetCollectionStatisticsRequest already carries. Because milvus's PrivilegeInterceptor treats a request with no privilege_ext annotation as "no permission required" and lets it through (fail-open), an authenticated but unauthorized account could read any collection's partition statistics, bypassing the intended PrivilegeGetStatistics check. PR #213 ("partition related apis require corresponding permissions") annotated the other partition APIs but missed this one. This brings GetPartitionStatistics under the same RBAC as GetCollectionStatistics by mirroring its annotation (object_type Collection, privilege PrivilegeGetStatistics, object_name_index 3 -> collection_name). Note: this is a permission tightening. Accounts that previously called GetPartitionStatistics without PrivilegeGetStatistics will now be denied once milvus core bumps this proto.

feat: add PrivilegeImportBinlog object privilege (#643) Binlog import (import option backup=true) and L0 import read Milvus's own internal storage layout rather than a caller staging area, which is outside the target collection's namespace. Add a cluster-level privilege so that capability can be authorized separately from the collection-level Import privilege.

enhance: add common.IDRange and a pre-allocated autoID range to ImportFile (#641) Add a generic common.IDRange {begin, end} message and an optional pre_allocated_auto_ids field on ImportFile. When set, an import materializes autoID primary keys from the given per-file range instead of allocating them locally, so the resulting primary keys are deterministic and known ahead of the import; unset keeps the existing allocate-during-import behavior. issue: #642 Signed-off-by: bigsheeper <yihao.dai@zilliz.com> Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>

fix: revert ttl_seconds to a plain int64, keeping command_id (#648) #647 declared PushClientCommandRequest.ttl_seconds `optional` so a server could apply a default to callers that omitted it while leaving an explicit 0 -- documented as "no expiry" -- alone. That reasoning does not survive contact with proto3 implicit presence, and the change costs source compatibility for every Go consumer. ## Presence does not reach the senders it needed to reach A client built against the previous definition emits nothing at all for an explicit 0, because a plain proto3 scalar at its zero value is not serialized. A server reading the field as absent therefore cannot distinguish that deliberate "never expire" from an unspecified field, whatever the field is declared as. Marking it optional gives presence only to senders rebuilt against the new definition -- which is exactly the population that did not need it. So a default keyed on absence silently converts every existing caller's deliberate "no expiry" into whatever the server picked. Presence bought nothing and hid that. ## It is a source-breaking change The generated field went from `int64` to `*int64`, so ordinary code stops compiling: &milvuspb.PushClientCommandRequest{TtlSeconds: 3600} // no longer builds The PR describing #647 called it additive. That was wrong: the wire format is unchanged, but every Go consumer with a struct literal or a comparison has to be edited. milvus itself needed changes in eight places. ## What this does Restores field 5 to `int64` and keeps `command_id`, which is genuinely additive and is the half of #647 that pulls its weight -- it lets a caller polling for one reply avoid re-transferring a client's whole reply history. Defaulting belongs to layers that can observe absence. In milvus that is the REST handler, which decodes ttl_seconds from JSON into a pointer and resolves it before the RPC; the RPC and the store keep the documented meaning, where 0 is no expiry. Regenerated with protoc v3.21.4 to match the checked-in files.

enhance: give ttl_seconds presence and let telemetry replies be fetched by id (#647) Two fields the client-telemetry surface needs, found while auditing it in milvus-io/milvus#51967. ## optional ttl_seconds The field is documented as "0 = no expiry, >0 = auto-expire in seconds", but a plain proto3 int64 cannot tell an omitted field from an explicit 0. That leaves the server no way to apply a default to callers who did not specify one without also redefining what an existing caller's 0 means -- and no way for that caller to ask for the old behavior back. Declaring it optional gives real presence, so a default belongs to "absent" alone and 0 keeps meaning no expiry for everyone. The generated getter still returns 0 for an unset field, so callers that only read the value are unaffected; the wire format is unchanged for anyone who sets it. ## command_id on GetClientTelemetryRequest Command replies are read back through GetClientTelemetry, which returns every reply a matching client has accumulated. A client retains its most recent 50 and a reply payload can reach 1MiB, so a caller polling for one specific answer transfers the entire history on every attempt -- roughly 50MB per poll in the worst case, repeatedly, for a single command's result. The new field narrows the response to the requested command. Empty keeps the existing behavior, so this is additive for current callers. Regenerated with protoc v3.21.4 to match the checked-in files; the bulk of the diff is the descriptor blob, which is rewritten in full whenever a field is added.

feat: [2.6] add FieldPartialUpdateOp for Array field partial update ops (#590) pr: #586 issue: https://github.com/milvus-io/milvus/issues/49241 Cherry-pick of #586 to the 2.6 release branch so that the 2.6 milvus backport PR can adopt ARRAY_APPEND / ARRAY_REMOVE semantics via UpsertRequest.field_ops. Proto surface is identical to master: - schema.proto: new FieldPartialUpdateOp message with OpType enum (REPLACE / ARRAY_APPEND / ARRAY_REMOVE). Enum ranges reserve namespaces for future JSON_* / NUM_* / SET_* / STRING_* ops. - milvus.proto: new repeated field UpsertRequest.field_ops = 11. No existing field numbers are reused; FieldData is unchanged so the addition is forward/backward compatible with older 2.6 clients and servers via proto3 unknown-field tolerance.

feat: add FieldPartialUpdateOp for Array field partial update ops (#586) issue: #49241 Introduce FieldPartialUpdateOp and attach it to UpsertRequest.field_ops so upsert requests can carry field-level partial-update directives. FieldData remains a pure data carrier to avoid leaking op semantics into InsertRequest / QueryResults / SearchResultData / msgstream paths and to prevent accidental echo-back on client-side read-modify-write flows. Phase 1 defines three ops: - REPLACE (default, full overwrite, preserves existing behavior) - ARRAY_APPEND (append payload to the tail of an Array row) - ARRAY_REMOVE (remove every element matching the payload) UpsertRequest.field_ops uses field number 11. Enum values reserve 1-9 for ARRAY_* ops, 10-19 for JSON_*, 20-29 for numeric counter ops, etc., so future ops can be added without breaking changes. Ops reference FieldData entries by field_name. Duplicate field_names and ops targeting fields not carried by fields_data are rejected by the server. proto3 unknown-field semantics keep the change backward compatible: older servers simply ignore field_ops and fall back to REPLACE.
