示例1: changeTypeToRestore
// change a tablet type to RESTORE and set all the other arguments.
// from now on, we can go to:
// - back to IDLE if we don't use the tablet at all (after for instance
// a successful ReserveForRestore but a failed Snapshot)
// - to SCRAP if something in the process on the target host fails
// - to SPARE if the clone works
func (agent *ActionAgent) changeTypeToRestore(ctx context.Context, tablet, sourceTablet *topo.TabletInfo, parentAlias topo.TabletAlias, keyRange key.KeyRange) error {
// run the optional preflight_assigned hook
hk := hook.NewSimpleHook("preflight_assigned")
topotools.ConfigureTabletHook(hk, agent.TabletAlias)
if err := hk.ExecuteOptional(); err != nil {
return err
}
// change the type
tablet.Parent = parentAlias
tablet.Keyspace = sourceTablet.Keyspace
tablet.Shard = sourceTablet.Shard
tablet.Type = topo.TYPE_RESTORE
tablet.KeyRange = keyRange
tablet.DbNameOverride = sourceTablet.DbNameOverride
if err := topo.UpdateTablet(ctx, agent.TopoServer, tablet); err != nil {
return err
}
// and create the replication graph items
return topo.UpdateTabletReplicationData(ctx, agent.TopoServer, tablet.Tablet)
