Google Spanner multiple queries in one round trip

Question

Is it possible to execute multiple queries against the Google Spanner in on round trip?

For example, I would like to run the following two queries in one round trip: (From performance concerns)

select * from Test1;

select * from Test2;

Answer 1

No, not in a single request. Current batching support is only for writes. Instead, send the 2 requests in parallel on separate requests.
