Subject Re: Frequent deletions
Date Mon, 12 Jan 2015 08:29:26 GMT

We gave 120G to JVM, while we have 140G memory on this machine.
We use the default merge policy("TieredMergePolicy"), and there are 54
segments in our index.
We tried to perform an optimization with different numbers of maxSegments
(53 and less)
it didn't help.
How much memory we need for 180G optimization?
Is every update deletes the document and creates a new one?
How can commit with expungeDeletes=true affect performance?
Currently we do not have a performance issue.

Thanks in advance.
