Hello all, I have a patch on CASSANDRA-21632 that bounds the BTI partition index preload and reads it in chunks. It has been reviewed and is sitting in Needs Committer, so I am looking for a committer willing to pick it up.
The short version: opening a BTI SSTable whose bloom filter is uninformative warms the whole Partitions.db one byte per page, which costs 90+ minutes of startup time on my 5TB nodes. The patch makes the amount warmed configurable and reads it in 1 MiB chunks instead. Default behaviour of reading everything is unchanged unless the property is set. Separately: I would like to join the ASF Slack so I could follow #cassandra-dev. The page at https://infra.apache.org/slack.html says I need someone already in the workspace to invite me. Is anyone here willing to do that? I would appreciate it. Thanks, -- Alexandre Viau CTO @ Flare
