The forum is giving me a warning that this topic is very old, but the discussion does not seem to have been resolved, and it is an extremely urgent, current topic for me.
Without using the “usafePurgeBucket” trick, will the disk usage ever level off on its own?
We recently replaced a single-node Couchbase 2.2.0 Memcached bucket with a Couchbase bucket. Our only reason for doing this was to work around the 1MB limit on the value size.
Our “documents” tend to be very small and short lived. I.e., a payload might be nothing but a boolean value, with a TTL in seconds. The active docs are 100% resident, about 500MB of data for a 3GB bucket, getting an average of 800 gets/sec and 150 sets/sec. The auto-compaction is set to the default of 30% and compaction events run frequently.
After two days in deployment, we are worrying about the disk usage, which has climbed to 3.5GB despite the data size being on the order of 500MB. The slope of the increase isn’t sustainable. Will Couchbase Server 2.2.0 level off or reverse this trend of extreme disk usage?
It would do a great deal for my level of comfort, if I could have some assurance that Couchbase buckets don’t continuously grow in size.
Thanks, and apologies for resurrecting such an old discussion.
