I think we should execute the statements immediately regardless of whether
autocommit
is set or not. Because Spanner handles DDL separately from transactions, there's no way to roll back DDL statements (which we will need to clearly document) and so I think having different behavior based onautocommit
is unnecessary.@AVaksman WDYT? Note that we now support executing multiple DDL statements at once which should alleviate the batching concern.

@larkee, no problem, I'll delete the line.
I'm writing a system test to check the case.
Also I've found out that in !autocommit mode DDLs are also not executed, even if one will call
commit()
. Will fix it in this PR as well.There was a problem hiding this comment.

@larkee, you know, about regarding autocommit mode... I think users don't usually go deep into frameworks code. So, we support DDLs separated with
;
, still users may use frameworks, which are generating and executing DDLs one by one. In this case it's probably better to look afterautocommit
mode, to make DDLs pumping up in !autocommit mode - to execute them all at once little bit later.There was a problem hiding this comment.

Hmm, that's a good point. In that case, we'll need to add
run_prior_DDL_statements()
tocommit()
as currently the statements aren't being executed even whencommit()
is called.
