> For every read request as a part of org.apache.cassandra.db.ReadCommand#executeLocally logic we parse CompactionOptions in withoutPurgeableTombstones:
> {code}
> public boolean onlyPurgeRepairedTombstones()
> {
> return Boolean.parseBoolean(params.options().get(AbstractCompactionStrategy.ONLY_PURGE_REPAIRED_TOMBSTONES));
> }
> {code}
> It costs us ~0.2% CPU
> we can save the parsed value into CompactionOptions to avoid it.
