- Issues
- MultiGet makes no progress when the first key's value is in a blob file and exceeds `value_size_soft_limit`
- One `SeekToFirst()` permanently disables `max_sequential_skip_in_iterations` for the rest of the iterator's life
- `WAL_size_limit_MB` is enforced as a file count derived from the largest archived WAL, so the archive is pruned far below the limit — and wiped entirely at the boundary
- Stats history deltas use an unguarded uint64 subtraction, so Statistics::Reset() records counts near 2^64 (also persisted to disk)
- kTriggerCompaction is never re-registered, so time-based compaction set via SetOptions never fires on an idle DB
- FIFO max_data_files_size drops far more user data than its budget requires: the trimming loop subtracts a flat per-file average instead of each file's real size
- Add range-based DB split and merge utilities (#15240)
- Preserve caller C4309 warning state in util/math.h
- Validate CuckooTableReader table geometry against file size
- Add bearer-scoped WAL index supersession records
