描述

Jira Link: DB-19492

Via yb_tablet_metadata view, it might be easy/helpful to expose information about tablet sizes for each replica.

(Much like Timur added support for it in the yb-master UI:

https://github.com/yugabyte/yugabyte-db/issues/29407#issuecomment-3552687883

in the "Raft Config/Replica" Info column).

(Customers would find it helpful to have this in a queryable manner rather than just in the UI).

Just like you show replica IP addresses as an array in yb_tablet_metadata view (see screenshot), we could add the active_ssts_size and wals_size as two additional array columns.

研究方向
Examine the existing yb tablet metadata view definition in the codebase. Study the implementation in the yb master UI that shows tablet sizes (issue #29407). Determine how to retrieve active ssts size and wals size per replica and add them as array columns to the view. Look for relevant source files like src/yb/master/... or src/yb/catalog/... The assignee should provide a PR.
