Run compaction on keyspaces and tables from node operations in OpsCenter.
Run compaction on keyspaces and tables from node operations in OpsCenter. Compaction
frees up disk space occupied by old SSTables and improves read performance by
incrementally replacing old SSTables with compacted SSTables.
For information about manually running a compaction, see the corresponding nodetool compact command. For conceptual information, see Compaction strategies.
