MartijnVisser opened a new pull request, #29837:
URL: https://github.com/apache/flink/pull/29837
## What is the purpose of the change
Many code examples in the documentation don't compile against master or
still use deprecated APIs. This PR fixes the Java examples and removes the
Scala DataStream API examples. SQL and Python examples follow in later commits,
so this stays a draft until those are done.
## Brief change log
- Call `cache()` on a transformation result (FLINK-30097)
- Fix 27 Java examples that don't compile
- Replace deprecated APIs in Java examples: `fromData`, Sink V2, the
Source API, `staticArguments`, `createCatalog` and `Schema`-based time
attributes
- Remove the Scala DataStream API examples, which use an API that was
removed in 2.0
The code changes are applied to the Chinese pages as well. Prose changes
there are left for translation.
## Verifying this change
Every changed Java example was compiled against the master classpath: it
fails before the change and compiles after it. The docs build hasn't been run
yet.
