             Summary: Tune DocumentNodeStore setup for indexing flow for index 
command
                 Key: OAK-6523
                 URL: https://issues.apache.org/jira/browse/OAK-6523
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: run
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra
            Priority: Minor
             Fix For: 1.8


Currently oak-run index command uses default DocumentNodeStore setup for all 
actions. It would be better if we can tune the DocumentNodeStore for specific 
actions.

For e.g. for read only indexing phase we should configure
# Persistent cache for previous documents and disable it for nodes and children
{noformat}
 -Doak.documentMK.persCache="temp/cache,size=4096,binary=0,-nodes,-children"
{noformat}
# Configure cache size to some percentage of allocated heap. To start with say 
50%

Any such tuning should only be done if it is not done explicitly i.e. it should 
be possible to override such settings
