Subject Compactions nice to have features
Date Sat, 04 Oct 2014 05:34:47 GMT
I am thinking about the following:

1. Compaction On/Off per CF, Table, cluster. Both: minor and major

Good during bulk load.

- Disable compaction for table 'T'
- Load 1B rows
- Enable compaction for table 'T'

2. Local Compaction I/O throttle

Set I/O limit per RS

3. Rack Compaction I/O throttle

Set I/O limit per server rack. Good to control uplink bandwidth.

4. Cluster Compaction I/O throttle. Good to avoid compaction storms
