------------------------------------------
Summary: [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
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.
