ydb-platform/ydb#10482
Here new functionality is added: system view partition_stats now has rows for datashard followers and new column FollowerId.
For example:

select * from `/local/.sys/partition_stats` where Path = '/local/Followers'

now returns several records like that

AccessTime	CPUCores	CoordinatedTxCompleted	DataSize	FollowerId	ImmediateTxCompleted	InFlightTxCount	IndexSize	LastTtlRowsErased	LastTtlRowsProcessed	LastTtlRunTime	NodeId	OwnerId	PartIdx	Path	PathId	RangeReadRows	RangeReads	RowCount	RowDeletes	RowReads	RowUpdates	StartTime	TabletId	TxRejectedByOutOfStorage	TxRejectedByOverload	UpdateTime
