The faster you insert data, the faster - you need to compact in order to keep the sstable count down, - but in general, setting this to 16 to 32 times the rate you - are inserting data is more than sufficient. Setting this to - 0 disables throttling. Note that this account for all types - of compaction, including validation compaction. - stream_throughput_outbound_megabits_per_sec: - type: int - default: 200 - description: > - Throttles all outbound streaming file transfers on nodes to the - given total throughput in Mbps. This is necessary because Cassandra - does mostly sequential IO when streaming data during bootstrap or - repair, which can lead to saturating the network connection and - degrading rpc performance. When unset, the default is 200 Mbps - or 25 MB/s. 0 to disable throttling. - - tombstone_warn_threshold: - type: int - default: 1000 - description: > - When executing a scan, within or across a partition, we - need to keep the tombstones seen in memory so we can return - them to the coordinator, which will use them to make sure - other replicas also know about the deleted rows.
