VTGate in a cell doesn't see Keyspaces without replica in that particular cell
bernardhalas opened this issue · comments
Scenario: Vitess deployed via operator. Cluster contains 3 cells. Keyspace contains replica just in one of the cells (zone1): cluster.yml
Problem: VTGates in other two cells (zone2, zone3) do not have the visibility of the keyspace (i.e. show databases against VTGate in zone2 and zone3 doesn't list the keyspace).
Opening this one as an issue as per a relevant discussion on Slack.
Unfortunately, this is a limitation in Vitess itself. VTGates look for keyspace info in their cell-local topology, and cell-local topology info is populated by VTTablets from that keyspace in that cell. If there are no tablets for a given keyspace in a given cell, then there's no one to populate the keyspace entry in that cell. It's definitely fixable, but the fix should be in Vitess rather than here in the operator.
Thank you for the explanation of the behavior. From my perspective this issue can be closed now as the behavior is not buggy and matching the expectation.
@bernardhalas could you create an issue on the vitess repo for this? thanks!
