-----------------------------------
Summary: Add options to disable creating job-id subdirectories
under the checkpoint directory
Key: FLINK-33057
URL: https://issues.apache.org/jira/browse/FLINK-33057
Project: Flink
Issue Type: Improvement
Components: Runtime / Checkpointing
Affects Versions: 1.19.0
Reporter: Zakelly Lan
Assignee: Zakelly Lan
By default, Flink creates subdirectories named by UUID (job id) under
checkpoint directory for each job. It's a good means to avoid collision.
However, it also bring in some effort to remember/find the right directory when
recovering from previous checkpoint. According to previous discussion (Yun
Tang's and Stephan Ewen's ), I think it would be useful to add an option to
disable creating the UUID subdirectories under the checkpoint directory. For
compatibility considerations, we create the subdirectories by default.
