linliu-code opened a new pull request, #12297:
URL: https://github.com/apache/hudi/pull/12297
### Change Logs
Currently `HoodieMergedLogRecordScanner` could use
`HoodiePreCombineAvroRecordMerger` to merge log records, which treats all the
records from the same batch, and does not respect the order of records across
different batches. Such that commit time merging logic is broken.
Therefore, we use the configured merger instead.
### Impact
Fix the bug for commit time merging.
### Risk level (write none, low medium or high below)
Medium.
### Documentation Update
_Describe any necessary documentation update if there is any new feature,
config, or user-facing change. If not, put "none"._
- _The config description must be updated if new configs are added or the
default value of the configs are changed_
- _Any new feature or user-facing change requires updating the Hudi website.
Please create a Jira ticket, attach the
ticket number here and follow the
[instruction](https://hudi.apache.org/contribute/developer-setup#website) to
make
changes to the website._
