thanks, Edward. In my test, when I changed to leveled strategy, the compaction can't finish for the reason that we have 700G new data every day!
what can I do if I want to save the comapction space? zhangcheng From: Edward Capriolo Date: 2012-05-14 10:14 To: dev; zhangcheng Subject: Re: how to upgrade my cassadra from SizeTieredCompaction to LeveledCompactiom As soon as you use the CLI to change the compaction strategy for a column family Cassandra will consider all SSTables level 0 and being level-ing them. With that much data, think hard before making the change. You have to understand how level ed will work with your workload.
