Re: Setting up smoosh for database compaction

4.0 is still in development today. If you tweak compaction settings and have very large shards, do take care to leave some disk space headroom to allow the compaction process to take place. Basically don't run your disks at 90% in production without experience there. ;) Kyle On Thu, Aug 19, 2021

Re: Setting up smoosh for database compaction

Hi Paul, I think that’s reasonable though do note that compaction is also for performance, even if you never update or delete a document, as couchdb defers rebalancing the b+tree disk structures until then (i.e, couchdb isn’t adhering to the b+tree algorithm from literature). Left uncompacted

Re: Setting up smoosh for database compaction

Re: Setting up smoosh for database compaction

Setting up smoosh for database compaction
