Change subject: [metrics] Add table level metrics column_count and schema_version on master ...................................................................... [metrics] Add table level metrics column_count and schema_version on master This patch adds some table level metrics on master. - column_count: The table's newest schema column count. Since too many column count will lead to bad performance and space amplification, we can add some monitor alerts based on this metric after this. - schema_version: The table's schema version. Too many or too frequently schema changes is also a metric worth to be monitored.
