Rajesh Balamohan commented on TEZ-4135: --------------------------------------- Sure, TEZ-3645 should be helpful as well in. Will check. Thanks [~jeagles]. "codec.createInputStream" explicitly creates 256KB buffer, but in this case tez already has info on the decompressed and compressed bytes. So it can reduce the memory requested in such cases. > Improve memory allocation when executing in-memory reads > -------------------------------------------------------- > > Key: TEZ-4135 > URL: https://issues.apache.org/jira/browse/TEZ-4135 > Project: Apache Tez > Issue Type: Improvement > Reporter: Rajesh Balamohan > Priority: Major > Attachments: Screenshot 2020-03-16 at 6.34.42 PM.jpg > > > !Screenshot 2020-03-16 at 6.34.42 PM.jpg|width=824,height=575! -- This message was sent by Atlassian Jira (v8.3.4#803005)
