Description

cassandra-cli: output from create cf command

[default@cqldb]  create column family supa_dupa2 with keys_cached_save_period = 124000;

No enum const class org.apache.cassandra.cli.CliClient$ColumnFamilyArgument.KEYS_CACHED_SAVE_PERIOD

cassandra-cli: help create column family

- keys_cached_save_period: Duration in seconds after which Cassandra should
  safe the keys cache. Caches are saved to saved_caches_directory as
  specified in conf/Cassandra.yaml. Default is 14400 or 4 hours.

  Saved caches greatly improve cold-start speeds, and is relatively cheap in
  terms of I/O for the key cache. Row cache saving is much more expensive and
  has limited use.

cqlsh: documentation for create column family options

key_cache_save_period_in_seconds	14400	Number of seconds between saving key caches.

cqlsh: this actually works
