Thanks Ryan for preparing the report. Some small suggestions keep as much as you want: - "Ongoing discussion for adding secondary indexes, but the timeline is unclear" -> "Started discussion for adding secondary indexes. Early phase." - Stared discussion on spec update to allow efficient column updates - File Format API has been merged, work started on TCK - Flink only maintenance (no external system needed)
