- Issues
- FR: Commit an app-supplied DDL tag value atomically alongside a DDL operation
- Distributed table async-insert queue files written by 26.8.9 are unreadable by 26.7.4
- LOGICAL_ERROR / abort: a v2 patch part plus a pending `ALTER MODIFY COLUMN` read by a sorting key column's `DEFAULT` aborts both `SELECT` and the materializing mutation
- Lazy `FINAL`: lazy index analysis for the fallback path
- Use the primary key index for `pointInEllipses` over key columns
- FR: Cluster-wide Keeper-mediated session-scoped advisory locks
- Sliced read pool for reading in order
- Do not build aggregate function states from omitted fields in `aggregate_function_input_format` = `value`
- Do not use or carry forward a projection whose parent column is read at another type
- WITH ROLLUP: the input merge combines nothing, every level merge is single-threaded, the sort gets one run per chunk, and the window above pays a serial scatter — TPC-DS query_67 -45%
