> {code}
> This is a regression in that there were multiple (6 ms) delays before the
> flush can finish, waiting for the metrics table to be registered.
> When first region of the table is opened on region server, we can proactively
> register table metrics.
> This would avoid the penalty on first flushes for the table.
