-----------------------------------

             Summary: RDBDocumentStore: docs obtained from cache may need revalidation before
returned to caller
                 Key: OAK-8264
                 URL: https://issues.apache.org/jira/browse/OAK-8264
             Project: Jackrabbit Oak
          Issue Type: Technical task
          Components: rdbmk
            Reporter: Julian Reschke
            Assignee: Julian Reschke


The cache internally invalidates documents by setting the {{lastCheckTime}} to 0. When a document
like that is returned from the cache, it needs to be rechecked in the persistence. This currently
happens for {{find()}}, but not for {{getIfCached()}} or internal methods such as {{readDocumentsCached()}}.
This may cause unneeded JDBC roundtrips when a document like that indeed changed in the meantime
and needs to be updated in the database.
