Subject Schema size
Date Fri, 25 May 2012 10:25:53 GMT
 Hi All,

I have a question about schema cleaning in cassandra.

I use cassandra version 1.0.9. I have 5 keyspaces and about 1500 column
family per keyspace. After dynamically creating and deleting CF my schema's
sstables  size were very high. For example size of Migrations was 45 GB and
Schema sstable size was 45 GB whereas all data size was about 10 GB.

Why schema grow was so fast? And how may I cleanup schema or later schema
cleanup itself?

Best regards,
