Caching has quite change a lot in 1.1. See <http://www.datastax.com/dev/blog/caching-in-cassandra-1-1> http://www.datastax.com/dev/blog/caching-in-cassandra-1-1
You need to set appropriate value in cassandra conf : key_cache_size_in_mb, key_cache_save_period and row_cache_size_in_mb. You will probably need to change the caching properties on CF with ALL or ROWS_ONLY if you want to enable rows caching. Something like this: create column family Application with caching='ALL'; By default, only keys are cached. - Pierre From: cyril auburtin [mailto:cyril.aubur...@gmail.com] Sent: dimanche 6 mai 2012 12:22 To: user@cassandra.apache.org Subject: Re: creating keyspace with 1.1 and one more thing For migration 0.7.10 ->1.1 I had to remove rows_cached, keys_cached, and key_cache_save_period from CF declarations?

If you are using cli, use instead: create keyspace Excelsior with placement_strategy='SimpleStrategy' and strategy_options = [{replication_factor:1}] From: cyril auburtin [mailto:cyril.aubur...@gmail.com] Sent: Sunday, May 06, 2012 10:31 AM To: user@cassandra.apache.org Subject: creating keyspace with 1.1 Hello I have just installed cassandra 1.1 CREATE KEYSPACE Excelsior WITH strategy_class = 'SimpleStrategy' AND strategy_options:replication_factor = 1; gives this error: Syntax error at position 85: mismatched input ':' expecting '=' I've looked in changes but didn't found Thanks
