Subject [jira] [Commented] (SOLR-9506) cache IndexFingerprint for each segment
Date Tue, 18 Oct 2016 14:37:58 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15585612#comment-15585612

Pushkar Raste commented on SOLR-9506:
-------------------------------------

I did not upload the patch with parallelStream. In SolrIndexSearcher where we compute and
cache per segment indexfingerprint try switching from {{stream()}} to {{parallelStream()}}
and you will see {{PeerSyncTest}} fails.

> The IndexFingerprint is cached per index searcher. it is quite useless during high throughput
indexing. If the fingerprint is cached per segment it will make it vastly more efficient to
compute the fingerprint
