bolt -> etcd. Compaction happens in etcd data-model. defrag would be bbolt operation.
When user should enlarge that time ?

done. have change to 'etcd' from 'bolt'.
Q: When user should enlarge that time ?
A: In more then 5,000 nodes k8s cluster.

Should rename to defaultBatchInterval.
By 'minimum,' we mean that the interval should be adjusted to 10ms if users set a smaller value, but clearly, the current implementation does not reflect this.
In mvcc/kvstore_compaction.go:store.scheduleCompaction() func, users can set the compaction number by "experimental-compaction-sleep-interval". However, the sleep interval is a constant btw every compaction loop which is 10ms.
I wanna test how long the interval is perfect in my huge k8s cluster if I can set this param by "experimental-compaction-sleep-interval".
