Monitor a running workflow
sharding & workflows
// what it does
workflow list shows all workflows with their numbers; workflow show tracks one workflow's copy progress and replication lag — what you watch during the hours-long copy phase of a big table move.
// shell
$ pscale workflow list mydb main$ pscale workflow show mydb main 1// gotcha
Wait for the copy phase to finish AND replication lag to reach ~zero before any traffic switching; switching against a lagging target serves stale reads.
