ASF GitHub Bot commented on ARROW-1808: --------------------------------------- wesm opened a new pull request #1337: ARROW-1808: [C++] Make RecordBatch, Table virtual interfaces for column access URL: https://github.com/apache/arrow/pull/1337 While this will cause some minor API breakage in parquet-cpp and some other downstream users, this is reasonably long overdue. It will permit implementations of the RecordBatch or Table interface that do lazy IO / data loading or lazy materialization of columns. I will write a patch to fix up parquet-cpp, and will look to see if glib is easy to fix. There's no good way to go about merging this patch since a green build is not possible, so once we're happy with the patch, I can merge this patch and then work on getting a green build in parquet-cpp so we don't have a broken build there for too long ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
