Marcel Reutegger created OAK-2592: ------------------------------------- Summary: Commit does not ensure w:majority Key: OAK-2592 URL: https://issues.apache.org/jira/browse/OAK-2592 Project: Jackrabbit Oak Issue Type: Bug Components: core, mongomk Reporter: Marcel Reutegger Assignee: Marcel Reutegger Fix For: 1.4
The MongoDocumentStore uses {{findAndModify()}} to commit a transaction. This operation does not allow an application specified write concern and always uses the MongoDB default write concern {{Acknowledged}}. This means a commit may not make it to a majority of a replica set when the primary fails. From a MongoDocumentStore perspective it may appear as if a write was successful and later reverted. See also the test in OAK-1641. To fix this, we'd probably have to change the MongoDocumentStore to avoid {{findAndModify()}} and use {{update()}} instead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
