Public bug reported: Currently the MetadataProxyHandler is monitoring more tables than it's required to [0][1]. Analyzing the code, only the Port_Bindings and Datapath_Bindings table would be necessary.
The more tables it monitors, the bigger the burden is on OVSDB to keep all the in-memory replicas updated. In special, the Chassis table can generate a lot of events due to the agents health check mechanism in the OVN driver so, not monitoring it could prevent a lot of events from being set across the fabric.
