示例1: DeleteTablet

// DeleteTablet removes a tablet record from the topology:
// - the replication data record if any
// - the tablet record
func DeleteTablet(ctx context.Context, ts topo.Server, tablet *topodatapb.Tablet) error {
	// try to remove replication data, no fatal if we fail
	if err := topo.DeleteTabletReplicationData(ctx, ts, tablet); err != nil {
		if err == topo.ErrNoNode {
			log.V(6).Infof("no ShardReplication object for cell %v", tablet.Alias.Cell)
			err = nil
		}
		if err != nil {
			log.Warningf("remove replication data for %v failed: %v", topoproto.TabletAliasString(tablet.Alias), err)
		}
	}

	// then delete the tablet record
	return ts.DeleteTablet(ctx, tablet.Alias)
}
