[jira] [Commented] (OAK-3774) Tool for detecting references to pre
compacted segments
[ https://issues.apache.org/jira/browse/OAK-3774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15058016#comment-15058016 ]
Michael Dürig commented on OAK-3774:
------------------------------------
Initial version at http://svn.apache.org/viewvc?rev=1720117&view=rev
The graph run mode of {{oak-run}} now takes {{--gc}} causing it to write a graph of gc generations:
{noformat}
nodedef>name VARCHAR
2
0
5
4
edgedef>node1 VARCHAR, node2 VARCHAR, weight INT
5,4,34
{noformat}
This means there are gc generations 0, 2, 5, and 4. Generations 5 has 34 referenced to generation 4.

> While OAK-3560 allows us to detect reference to pre compacted segments through manual inspection, we also need tooling to help detect such cases on site, during longevity tests and for UT/IT.
