Siyao Meng updated HDDS-13470:
------------------------------
Resolution: Won't Do
Status: Resolved (was: Patch Available)
> Use partitioned filters for new SST files
> -----------------------------------------
>
> Key: HDDS-13470
> URL: https://issues.apache.org/jira/browse/HDDS-13470
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Labels: pull-request-available
>
> *Warning: Testing only, for now.*
> We would only want to enable this for big SSTs we are writing as in
> HDDS-13003 (Snapshot Compaction / Snapshot Defragmentation project).
> This could benefit with cache hit ratio and reduced I/O. Thus potential
> performance improvement. For more, see:
> https://github.com/facebook/rocksdb/wiki/Partitioned-Index-Filters#what-is-partitioned-indexfilters
> Shouldn't have upgrade concerns as rocksdb v7.7.3 supports it already. But it
> could break things that operates on SST files directly (e.g. some fs snapshot
> impl).
> It affects newly written SST files only.
