This seems to be a known issue with Xcode

There might be a way to configure Xcode to emit more debug symbols but the
best way is probably to develop on Linux in Docker or in a VM

MacOS High Sierra.
If you do a build (/debug, make) and then attach lldb to a test (lldb
-- compute_test), then try to access a class's members (e.g.
ArrayData's buffers), the error pops up.

Hi Wes.
Thanks, your command worked and I am able to attach a debugger.
However, I get the following error for some operations:
error: Couldn't lookup symbols:
__ZNKSt3__110shared_ptrIN5arrow5ArrayEEptEv
It seems that not all symbols are being loaded. I did a debug build
(according to README)

Hi Michael,
I think ArrowFileReader takes SeekableByteChannel so it's possible to only
read the metadata for each record batches and skip the data. However it is
not implemented.
If the input Channel is not seekable (for example, a socket channel) then
you would need to read the body for each rec
Hi all,
I am looking for a quick way to look up the total row count of a data set
stored in Arrow’s random access file format using the Java API. Basically, a
quicker way to do this:

List blocks = reader.getRecordBlocks();
int nRows = 0;
