-----------------------------------
Summary: RDBDocumentStore: version GC does not scale when there
are many docs with long paths
Key: OAK-6806
URL: https://issues.apache.org/jira/browse/OAK-6806
Project: Jackrabbit Oak
Issue Type: Improvement
Components: rdbmk
Reporter: Julian Reschke
Assignee: Julian Reschke
Due to the way the RDB RevisionGC looks for split documents, it doesn't perform
well at all in the presence of many documents with long paths.
The reason is that we currently do not have a column for SDTYPE, and thus use
pattern matching on the document IDs instead. However, once a document has long
path in the document store, it appears to the GC has candidate split document,
and thus is always read upon GC.
