-------------------------------------
Summary: Make compression of system tables configurable
Key: CASSANDRA-5548
URL: https://issues.apache.org/jira/browse/CASSANDRA-5548
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.2.2
Reporter: John Sanda
I know that compression is enabled for SSTables by default. And the default
compression used is snappy. I can disable or change the compression used with
the sstable_compression storage option. I recently learned that compression is
also enabled for system tables as well; however, the compression for system
tables cannot be changed. This means that if snappy is available for the
JRE/platform, then snappy compression will be used for system tables. As I
understand, compression for system tables is disabled only when snappy is not
available. In that scenario, I choose a different implementation of ICompressor
for user tables, but I have no such option for system tables. Nor do I have the
option to disable compression for all tables.
