> --------------------------------

> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran

>
> 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.
