[jira] [Created] (OAK-8264) RDBDocumentStore: docs obtained from
cache may need revalidation before returned to caller
Julian Reschke created OAK-8264:
-----------------------------------
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.
