Subject [jira] [Commented] (SOLR-4092) Test failure in org.apache.solr.core.TestConfig.testDefaults31
Date Sun, 18 Nov 2012 21:20:57 GMT


Shawn Heisey commented on SOLR-4092:

In order to be affected by this, the user must be running running Solr 4.1 with no ramBufferSizeMB
in their config.

With the Solr upgrade from 3.x, Solr's memory footprint will be drastically altered no matter
what happens with the default ramBufferSizeMB.  In many cases that footprint will be significantly
smaller than it was before, so any change from this increase may be in the noise.  The user
may be surprised by new index segments that are suddenly much larger, but since it comes with
better performance, I doubt there would be any major fallout.

My bias is to change the test, and leave ramBufferSizeMB at 100 for all luceneMatchVersion
values.  Or you could appeal to binary perfection and make it 128. :)
