--------------------------------------------
Summary: TWCS - Provide a flag to pick a time when compaction
happens for the n-1 window
Key: CASSANDRA-19715
URL: https://issues.apache.org/jira/browse/CASSANDRA-19715
Project: Cassandra
Issue Type: New Feature
Reporter: Venkata Naladala
Below are the settings for the TWCS. With the settings below, the compaction
for the n-1 window happens at around 00:00 UTC on all the nodes in the cluster.
This causes a spike in IO utilization on the entire cluster, which in turn
increases the read latencies.
{{{}compaction = { 'class' :
'org.apache.cassandra.db.compaction.TimeWindowCompactionStrategy',
'compaction_window_size' : 1, 'compaction_window_unit' : 'DAYS',
'max_threshold' : 32, 'min_threshold' : 4{}}}}
Requesting to provide a new option for TWCS where we can specify when the
compaction for n-1 window happens. This way, we can provide a custom time
instead of the default time(beginning of the new window) so that we can pick
low-traffic hours and avoid impacting the customer.
