----------------------------------------
Summary: Close the channel unspilling thread pool after restore
Key: FLINK-23095
URL: https://issues.apache.org/jira/browse/FLINK-23095
Project: Flink
Issue Type: Improvement
Components: Runtime / Task
Reporter: Dawid Wysakowicz
Fix For: 1.14.0
Currently we keep around the {{StreamTask#channelIOExecutor}} for the entire
life cycle of the {{StreamTask}} and we keep unnecessary alive threads. We
could close it right after we finish the restore of the gates.
