Ethan Guo updated HUDI-7848:
----------------------------
Story Points: 8
> Fix the Comparable type of the ordering field value stored in delete record
> ---------------------------------------------------------------------------
>
> Key: HUDI-7848
> URL: https://issues.apache.org/jira/browse/HUDI-7848
> Project: Apache Hudi
> Issue Type: Bug
> Reporter: Ethan Guo
> Assignee: Lin Liu
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.0.0
>
>
> The delete records stored in the log file may contain different Comparable
> type compared to the ordering field stored in the table schema, which can
> cause class cast excepting when comparing the ordering values in the event
> time-based merging. To get rid of this issue, right now the workaround is to
> cast the ordering number to long for comparison.
