示例1: allocateStoreIDs

// allocateStoreIDs increments the store id generator key for the
// specified node to allocate "inc" new, unique store ids. The
// first ID in a contiguous range is returned on success.
func allocateStoreIDs(nodeID roachpb.NodeID, inc int64, db *client.DB) (roachpb.StoreID, error) {
	r, err := db.Inc(keys.StoreIDGenerator, inc)
	if err != nil {
		return 0, util.Errorf("unable to allocate %d store IDs for node %d: %s", inc, nodeID, err)
	}
	return roachpb.StoreID(r.ValueInt() - inc + 1), nil
}
