Subject Too many sstables with DateTieredCompactionStrategy
Date Mon, 29 Feb 2016 13:36:34 GMT

Hi all,

We are using below compaction settings for a table

compaction = {'timestamp_resolution': 'MILLISECONDS',
'max_sstable_age_days': '365', 'base_time_seconds': '60', 'class':

But it is creating too many sstables. Currently number of sstables
is 40000. We have been injecting data for the last three days.

We have set the compactionthroughput to 128 MB/s

$ nodetool getcompactionthroughput

Current compaction throughput: 128 MB/s

But this is not helping. 

How can we control the number of sstables in this case?

Thanks and Regards
