Subject [jira] [Updated] (SOLR-9712) Saner default for maxWarmingSearchers
Date Fri, 16 Dec 2016 02:41:58 GMT


Yonik Seeley updated SOLR-9712:
    Attachment: SOLR-9712.patch

OK, here's the final patch that I'll probably commit tomorrow. Most maxWarmingSearcher specifications
have been removed from test configurations.  This doesn't really reduce coverage much due
to the fact that maxWarmingSearchers=1 (the default) is not special-cased so all code paths
will still be exercised with concurrent commits.

> As noted in SOLR-9710, the default for maxWarmingSearchers is Integer.MAX_VALUE which
is just crazy. Let's have a saner default. Today we log a performance warning when the number
of on deck searchers goes over 1. What if we had the default as 1 that expert users can increase
if needed?
