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.

>
> LZO is a lossless data compression algorithm which is focused on compression
> and decompression speeds.
> This will enable Apache Beam sdk to compress/decompress files using LZO
> compression algorithm.
> This will include the following functionalities:
> # compress() : for compressing files into an LZO archive
> # decompress() : for decompressing files archived using LZO compression
> Appropriate Input and Output stream will also be added to enable working with
> LZO files.
