Anthony Abate commented on ARROW-7156:
--------------------------------------
[~wesm] - I should also point out the C# library on Net Framework is not even
stable in its current state due to random crashes related to this: ARROW-7040
(I have a local build that fixes is this - so I can make a PR for this one)
Regarding the integration tests - since C# is not using the C++ libs, how do
the integration tests work? (i can volunteer some of my time on this, but I may
have a lot of questions)

> I have a 30 gig arrow file with 100 batches. the largest batch in the file
> causes get batch to fail - All other batches load fine. in 14.11 the
> individual batch errors.. in 15.1.1 the batch crashes R studio when it is used
> *14.1.1*
> {code:java}
