@simsurace I tested the Julia client against all the servers, and they all
ran without error (except Ruby server which I'm having trouble with for
unrelated reasons).
I also added some temporary code to the Julia client to write the resulting
data to an Arrow IPC file, then examined the file. I noticed a problem:
I would expect the schema to look like this:
```
a: int64
b: int64
c: int64
d: int64
```
But it looks like this:
```
a: list<: int64> not null
child 0, : int64
b: list<: int64> not null
child 0, : int64
c: list<: int64> not null
child 0, : int64
d: list<: int64> not null
child 0, : int64
```
It seems that the Julia library is wrapping the int64 columns in lists. Do
you know if this is a known issue with the Arrow Julia IPC stream reader?
