Enable the master to rebuild its metadata from client-side state after a restart, so that a fresh master process can recover segment and object location information without recomputation. - mooncake-store: add rebuild flow across client_service, master_service, master_client, rpc_service, segment and allocator - add rebuild_types.h defining the rebuild request/response types - add client_metadata_rebuild unit test and ha live-recovery test harness Co-Authored-By: Claude <noreply@anthropic.com>
Strip references to internal design/impl docs (section numbers like "impl doc §4.1" and internal .md filenames) from the HA rebuild code comments, so the comments are self-contained for public review. Comment-only change; no code logic modified. Co-Authored-By: Claude <noreply@anthropic.com>
Translate the remaining Chinese comments and assertion messages in the HA rebuild unit test to English, and replace the draft-era changelog header with a concise English summary of the seven tests, so the file is ready for public review. Also apply clang-format (ColumnLimit 80) across the HA rebuild files to satisfy the format check. Comment, message, and whitespace only; no test or code logic changed, and all seven unit tests still pass. Co-Authored-By: Claude <noreply@anthropic.com>
Add a standalone scale benchmark for the HA metadata rebuild feature that measures rebuild latency, scale across a key-count sweep, and recovery-window read latency and availability. Includes the benchmark client, its driver script, and a report of the measured results. Co-Authored-By: Claude <noreply@anthropic.com>
