Till Rohrmann created FLINK-5085: ------------------------------------ Summary: Execute CheckpointCoodinator's state discard calls asynchronously Key: FLINK-5085 URL: https://issues.apache.org/jira/browse/FLINK-5085 Project: Flink Issue Type: Bug Components: State Backends, Checkpointing Affects Versions: 1.1.3, 1.2.0 Reporter: Till Rohrmann Assignee: Till Rohrmann Fix For: 1.2.0, 1.1.4
The {{CheckpointCoordinator}} discards under certain circumstances pending checkpoints or state handles. These discard operations can involve a blocking IO operation if the underlying state handle refers to a file which has to be deleted. In order to not block the calling thread, we should execute these calls in a dedicated IO executor. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
