James Berragan updated CASSANDRA-19927: --------------------------------------- Authors: James Berragan Test and Documentation Plan: CircleCI Status: Patch Available (was: Open) > [Analytics] Deprecate old compression cache and move to using cache of > CompressionMetadata > ------------------------------------------------------------------------------------------ > > Key: CASSANDRA-19927 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19927 > Project: Cassandra > Issue Type: Improvement > Components: Analytics Library > Reporter: James Berragan > Priority: Normal > > The compression cache currently caches a single byte array for the > CompressionInfo.db file, this is a problem for large files as it involves > allocating and garbage collecting large memory segments, but also means that > every consumer of the bytes will instantiate a CompressionMetadata object and > allocate an individual BigLongArray to store the chunk offsets. This is > unnecessary as the CompressionMetadata is immutable and can be re-used. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
