cassandra-opstools

Generic tools and scripts to help operating Cassandra cluster

spcassandra-abortrepairs: Stops ongoing anti-entropy sessions on the local Cassandra host

spcassandra-autobalance: Automatically redistributes the tokens in a cluster so they are evenly distributed. Tries to move as few tokens as possible to achieve this. In a multi-DC setup, all datacenters must have the same number of nodes. Only useful when not using vnodes.

spcassandra-dsnitch: Outputs the score the Cassandra snitch has for every peer.

spcassandra-generate-repairs: Generates "nodetool repair" commands that repairs an entire cluster with small token ranges.

spcassandra-repairstats: Scans the Cassandra system log and displays readable statistics of finished and running repairs.

spcassandra-tombstones: Scans a sstable and prints number of tombstones for each partition.

spcassandra-truncate[all]hints: Truncates (all) hints on localhost toward the specified hosts.
