ASF GitHub Bot logged work on BEAM-8564: ---------------------------------------- Author: ASF GitHub Bot Created on: 10/Dec/19 21:01 Start Date: 10/Dec/19 21:01 Worklog Time Spent: 10m Work Description: amoght commented on issue #10254: [BEAM-8564] Add LZO compression and decompression support URL: https://github.com/apache/beam/pull/10254#issuecomment-564256222 While studying the code, we found that the airlift/ aircompressor library only requires some classes which are also present in apache hadoop common package(~3.9MB). Therefore, we are now thinking that if we make changes in the airlift/ aircompressor package, replacing the com.facebook.presto.hadoop with org.apache.hadoop.common and remove other compression mechanisms(like zstd, gzip etc) while only keeping the required LZO package. But if we go ahead with this approach, we will have to manually update this library whenever any changes are made to the airlift/aircompressor's LZO package. @lukecwik @gsteelman please provide your thoughts on this. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
