sql,server: execute update table metadata job on chan notify

Open xinhaoz opened this issue 1 year ago • 1 comments

This commit allows the update table metadata BG job to execute a run when signalled via a channel. Currently, the channel is passed to the statusServer which notifies the job via the newly added gRPC method, UpdateTableMetadataCache, which forwards the request to the node owning the job.

Summary:

Added UpdateTableMetadataCache grpc method on status server forwards request to node with update table metadata cache job.
Update table metadata cache job observes channel to start execution.
On every execution, the update job now increments the num runs metric.
