-F(json|yaml) ,--format(json|yaml)-
Specifies the format for the output, use either
jsonoryaml. The default is plain text.
Example
The actual output of compaction history is seven columns wide. The first three columns show the id, keyspace name, and table name of the compacted SSTable.

37638350-07ae-11e4-9b36-abc3a0ec9088 Keyspace1 Standard1The four columns to the right of the table name show the timestamp, size of the SSTable 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.
