> Enable ZLIB for streaming ingest
> --------------------------------
>
> Key: HIVE-20165
> URL: https://issues.apache.org/jira/browse/HIVE-20165
> Project: Hive
> Issue Type: Bug
> Components: Streaming, Transactions
> Affects Versions: 4.0.0, 3.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Major
> Attachments: HIVE-20165.1.patch
>
>
> Per [~gopalv]'s recommendation tried running streaming ingest with and
> without zlib. Following are the numbers
>
> *Compression: NONE*
> Total rows committed: 93800000
> Throughput: *1563333* rows/second
> $ hdfs dfs -du -s -h /apps/hive/warehouse/prasanth.db/culvert
> *14.1 G* /apps/hive/warehouse/prasanth.db/culvert
>
> *Compression: ZLIB*
> Total rows committed: 92100000
> Throughput: *1535000* rows/second
> $ hdfs dfs -du -s -h /apps/hive/warehouse/prasanth.db/culvert
> *7.4 G* /apps/hive/warehouse/prasanth.db/culvert
>
> ZLIB is getting us 2x compression and only 2% lesser throughput. We should
> enable ZLIB by default for streaming ingest.
