[jira] [Commented] (SOLR-6838) Bulk loading with the default of updateDocument blocks all indexing for long periods of time.

    [ https://issues.apache.org/jira/browse/SOLR-6838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14243117#comment-14243117 ] 

Mark Miller commented on SOLR-6838:
-----------------------------------

In a quick run, I see 3 large merges done by a concurrent indexing merge thread. Each time, this thread spends 10-20 seconds in IW#_mergeInit dealing with updates in BufferedUpdateStream#applyDeletesAndUpdates. This holds the IW lock and all indexing threads are blocked in updatePendingMerges or publishFlushedSegments.
