Hi there, I am updating compaction strategy from 'sized tiered' to 'leveled' and from http://www.datastax.com/dev/blog/leveled-compaction-in-apache-cassandra it is said:
When updating an existing column family, reads and writes can continue as > usual while leveling of existing sstables is performed in the background. > But I still see many old sstables with very large size and an old file date. So I am wondering is the updating of compaction done automatically? If yes, is there an estimate of time it will take? If not, what's the steps to do it manually? I've googled a lot but can't find something helpful. Thanks for any feedbacks and any help is of great appreciation.
