37638350-07ae-11e4-9b36-abc3a0ec9088 Keyspace1 Standard1The four columns to the right of the table name show the timestamp, size of the SSTtable before and after compaction, and the number of partitions merged. The notation means {tables:rows}. For example: {1:3, 3:1} means 3 rows were taken from one SSTable (1:3) and 1 row taken from 3 SSTables (3:1) to make the one SSTable in that compaction operation.
