  If you're increasing the ReplicationFactor:
   * Run "nodetool repair" to run an anti-entropy repair on the cluster. This is an intensive process so may result in adverse cluster performance.

+ == Can I Store BLOBs in Cassandra? ==
+ Currently Cassandra isn't optimized specifically for large file or BLOB storage, however there are ways to work around this.

+ These notes were taken from the Cassandra limitations section (http://wiki.apache.org/cassandra/CassandraLimitations):
+ ----
+ * Cassandra's public API is based on Thrift, which offers no streaming abilities -- any value written or fetched has to fit in memory.  This is inherent to Thrift's design; I don't see it changing.  So adding large object support to Cassandra would need a special API that manually split the large objects up into pieces.  Jonathan Ellis sketched out one approach in http://issues.apache.org/jira/browse/CASSANDRA-265.  As a workaround in the meantime, you can manually split files into chunks of whatever size you are comfortable with -- at least one person is using 64MB -- and making a file correspond to a row, with the chunks as column values.
