Subject Re: Arrow-Parquet integration location (Was: Arrow cpp travis-ci build broken)
Date Wed, 07 Sep 2016 00:27:13 GMT
Forgive me if interposing my first post for the Apache Arrow project on this thread is incorrect
procedure. 

What Julien proposes with each storage layer producing Arrow Record Batches is exactly how
I envision it working and would certainly make Arrow integration with SAS much more palatable.
 This is likely true for other storage layer providers as well.
