	// Map Reduce support
	SplitQuery(ctx context.Context, keyspace string, sql string, bindVariables map[string]interface{}, splitColumn string, splitCount int, reply *proto.SplitQueryResult) error

	// Topology support
	GetSrvKeyspace(ctx context.Context, keyspace string) (*topo.SrvKeyspace, error)

	// HandlePanic should be called with defer at the beginning of each
	// RPC implementation method, before calling any of the previous methods
	HandlePanic(err *error)
}

VTGateService is the interface implemented by the VTGate service, that RPC server implementations will call.
