-------------------------------------
Summary: Determine compression / compressionCodec at runtime to
avoid burning CPU cycles
Key: TEZ-1067
URL: https://issues.apache.org/jira/browse/TEZ-1067
Project: Apache Tez
Issue Type: Bug
Reporter: Rajesh Balamohan
- Based on the compressed data being written and its compression ratio, tez
should be able to pick up the best compression codec for the job.
- If the compression ratio is very poor, it should be possible to turn off
compression as well (which could save good amount CPU cycles).
