pnowojski commented on issue #6787: [FLINK-8577][table] Implement proctime
DataStream to Table upsert conversion
URL: https://github.com/apache/flink/pull/6787#issuecomment-441185723
I've started reviewing the code and as we talked offline, could you split
this PR into 4 commits:
- Add `fromAppendStream` and Deprecate `fromDataStream`
- Introduce `LastRow` Rules
- Introduce `LastRow` runtime functions
- Optimize upsert sources followed by `Calc`
? Having more, smaller, independent commits speeds up reviewing and help in
the future whenever someone is digging through git's commit history to
understand why/how was something implemented. Especially splitting of
refactoring/renaming commits from feature adding/changing or bug fixing commits
is important.
