Couchbase Sync Gateway
Covers Couchbase Sync Gateway’s compatibility with Couchbase Server and Couchbase Lite
Sync Gateway and Couchbase Server
| Users of Couchbase Server 6.0 should ensure they have addressed the known issue (MB-41255) by upgrading to one of the recommended Couchbase Server versions (6.0.5, 6.5.2, or 6.6.1). The known issue can cause re-balance failures and/or failed replica writes of deleted or expired documents that use Xattrs. This impacts Sync Gateway deployments running with shared bucket access enabled, which use Xattrs for metadata storage. |
