Description
_vt.vreplication
has new column,rows_copied
, which is updated periodically duringvreplication
work, to reflect the actual number of rows written on the target table.The value is written together with
time_updated
, so it does not get transactionally synced with each copy iteration, it follows closely though, and makes a good estimate.This will be later used by Online DDL to track Vreplication-based migration progress & ETA.
