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.
