the-other-tim-brown opened a new pull request, #13347:
URL: https://github.com/apache/hudi/pull/13347
### Change Logs
- Previously the log files were associated with the latest base file at the
time the commit starts. Since compaction planning or a successful compaction
causes a new base file, we need to check for conflicts with compaction for
these older table versions.
- Starting with table version 8, the log files are associated with a base
file based on the completion time so we don't rely on the current state of a
file group when creating these log files. That means we no longer need to check
compaction for conflicts which in turn allows for smoother operations on MoR
tables.
### Impact
- Allows async compaction to schedule and run without causing disruption to
other writers
### Risk level (write none, low medium or high below)
High, this is a core change to conflict detection.
### 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
