-------------------------------------
Summary: Create in-memory ifile writer for transferring smaller
payloads (follow up of TEZ-4075)
Key: TEZ-4088
URL: https://issues.apache.org/jira/browse/TEZ-4088
Project: Apache Tez
Issue Type: Bug
Reporter: Rajesh Balamohan
TEZ-4075 enabled data transfer over DME for smaller payloads. This helps in
reducing shuffle.
However, it still incurs disk IO cost (+flush) in producer side. It would be
good to retain smaller payloads in mem, so that disk IO costs can be saved.
