Wes McKinney created ARROW-6417: ----------------------------------- Summary: [C++][Parquet] Non-dictionary BinaryArray reads from Parquet format have slowed down since 0.11.x Key: ARROW-6417 URL: https://issues.apache.org/jira/browse/ARROW-6417 Project: Apache Arrow Issue Type: Improvement Components: C++, Python Reporter: Wes McKinney Attachments: 20190903_parquet_benchmark.py, 20190903_parquet_read_perf.png
In doing some benchmarking, I have found that binary reads seem to be slower from Arrow 0.11.1 to master branch. The comparison isn't quite apples-to-apples since I think these results were produced with different versions of gcc, but it would be a good idea to do some basic profiling to see where we might improve our memory allocation strategy (or whatever the bottleneck turns out to be) -- This message was sent by Atlassian Jira (v8.3.2#803003)
