---------------------------------
Summary: ExternalSortExec should aware of available memory of
container
Key: TAJO-562
URL: https://issues.apache.org/jira/browse/TAJO-562
Project: Tajo
Issue Type: Improvement
Components: physical operator
Reporter: Hyunsik Choi
Fix For: 0.8-incubating
ExternalSortExec spills intermediate data into disks when the number of tuples
exceeds some threshold. This way does not consider the available memory of
container, and it cannot utilize available memory well.
The objective of this issue is to improve ExternalSortExec to be aware of
available memory and spill intermediate data into disks when the allocated
memory is full.
