- Issues
- S3Queue: add SYSTEM DROP S3QUEUE FAILED FILES command
- Time64 KV key lookup with = loses rows after #117667
- `avg` rewrite builds `Float64 op Int128` and rejects a valid query
- Iceberg: an INSERT from 26.3 after a newer ClickHouse wrote the table corrupts the manifest list, the table becomes unreadable
- Iceberg writer never trims metadata-log: old metadata.json files can never be removed, storage and commit cost grow with every commit
- Keep the caches of a part when it is moved to another disk
- Do not lose the records of a `FileLog` chunk that fails
- PREWHERE lambda `*` over `USING` gets the key supertype: `LOGICAL_ERROR`
- Optional `variant` column seen as required: pre-`ADD COLUMN` files fail
- Iceberg: ClickHouse names its metadata file vN.metadata.json on tables that use NNNNN-uuid names, then expire_snapshots and remove_orphan_files refuse to run
