Hi all, I'd like to start a discussion on FIP-51: Support Per-Partition Bucket Count.
Today, a Fluss table and all of its partitions share a single bucket count fixed at table-creation time. Users who need more buckets for recent partitions must either over-provision every historical partition from day one, or accept that recent partitions are under-bucketed and become the read/write bottleneck. Before this FIP, the only way to change the bucket count was to create a new table and rewrite all data, including historical partitions already tiered to the lake. So, I'd like to propose FIP-51: Support Per-Partition Bucket Count [1] to make bucket.num alterable so that new partitions are written at the new bucket count while existing partitions are left untouched, with no data movement. Welcome your feedback and suggestions on this proposal. Looking forward to a productive discussion!
