[jira] [Created] (FLINK-14892) Add description for checkpoint
directory layout
Congxian Qiu(klion26) created FLINK-14892:
---------------------------------------------
Summary: Add description for checkpoint directory layout
Key: FLINK-14892
URL: https://issues.apache.org/jira/browse/FLINK-14892
Project: Flink
Issue Type: Improvement
Components: Documentation, Runtime / Checkpointing
Reporter: Congxian Qiu(klion26)
Fix For: 1.10.0
In FLINK-8531, we change the checkpoint directory layout to
{code:java}
/user-defined-checkpoint-dir
|
+ --shared/
+ --taskowned/
+ --chk-00001/
+ --chk-00002/
+ --chk-00003/
...
{code}
But the directory layout did not describe in the doc currently, and I found some users confused about this, such as[1][2], so I propose to add a description for the checkpoint directory layout in the documentation, maybe in the page {{checkpoints#DirectoryStructure}}[3]
