[jira] [Updated] (FLINK-25470) Add/Expose/Differentiate metrics of checkpoint size between changelog size vs materialization size
[ https://issues.apache.org/jira/browse/FLINK-25470?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuan Mei updated FLINK-25470:
-----------------------------
Description:
FLINK-25557 only resolves part of the problems.
Eventually, we should answer questions:
* How much Data Size increases/exploding
* When a checkpoint includes a new Materialization
* Materialization size
* changelog sizes from the last complete checkpoint (that can roughly infer restore time)
was:
Right now, the checkpoint size includes both changelog size + materialization size
We should have a way to separately report and show them in UI
