Subject [jira] Created: (JCR-1238) Change default value for maxMergeDocs
Date Tue, 27 Nov 2007 14:03:43 GMT
Change default value for maxMergeDocs

                 Key: JCR-1238
                 URL: https://issues.apache.org/jira/browse/JCR-1238
             Project: Jackrabbit
          Issue Type: Improvement
          Components: jackrabbit-core
            Reporter: Marcel Reutegger
            Priority: Minor

This is actually a left over from the time before JCR-197 was implemented. Back then index
merges were performed with the client thread and would hold up execution for a long time if
a large number of nodes were merged. The default value for maxMergeDocs limited this to 100'000
nodes, resulting in a couple of seconds for the merge operation.

This default value does not make sense anymore because index merges are performed in a background
thread and may take a long time without an effect on regular workspace operations. If a workspace
grows large it may cause performance degradation because the number of index segments increases
linearly when there are more than 100'000 nodes.

I propose to set the new default to Integer.MAX_VALUE
