[jira] [Updated] (FLINK-13955) Integrate
ContinuousFileReaderOperator with StreamTask mailbox execution model
[ https://issues.apache.org/jira/browse/FLINK-13955?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alex updated FLINK-13955:
-------------------------
Description:
The {{ContinuousFileReaderOperator}} spawns an additional ({{reader}}) thread and coordinates actions with it via {{checkpointLock}}. The operator may block, waiting for a notification from the {{reader}} thread, potentially preventing progress in mailbox loop.
This is similar to {{AsyncWaitOperator}} situation described in FLINK-12958.
