Merge pull request #3703 from citusdata/get_rid_of_side_channel 
Move connection establishment for intermediate results after query execution
 2020-04-07 17:21:30 +02:00
Önder Kalacı 70012dfd33 Do not error when an intermediate file does not exit (#3707) 
When the file does not exist, it could mean two different things.
First -- and a lot more common -- case is that a failure happened
in a concurrent backend on the same distributed transaction. And,
one of the backends in that transaction has already been roll
backed, which has already removed the file. If we throw an error
here, the user might see this error instead of the actual error
message. Instead, we prefer to WARN the user and pretend that the
file has no data in it. In the end, the user would see the actual
error message for the failure.

Second, in case of any bugs in intermediate result broadcasts,
we could try to read a non-existing file. That is most likely
to happen during development. Thus, when asserts enabled, we throw
an error instead of WARNING so that the developers cannot miss.
