CompressionMetadata is not shared across threads, we create a new one for each
read

Key: CASSANDRA-3427
URL: https://issues.apache.org/jira/browse/CASSANDRA-3427
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.1
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Fix For: 1.0.2
The CompressionMetada holds the compressed block offsets in memory. Without
being absolutely huge, this is still of non-negligible size as soon as you have
a bit of data in the DB. Reallocating this for each read is a very bad idea.
