jiasheng55 opened a new pull request #10323: [FLINK-14817][doc] Fix misleading documentation using method chaining… URL: https://github.com/apache/flink/pull/10323 … of Configuration ## What is the purpose of the change In the document, there are some misleading code examples, e.g. ``` // instantiate table environment TableEnvironment tEnv = ...tEnv.getConfig() // access high-level configuration .getConfiguration() // set low-level key-value options .setString("table.exec.mini-batch.enabled", "true") // enable mini-batch optimization .setString("table.exec.mini-batch.allow-latency", "5 s") // use 5 seconds to buffer input records .setString("table.exec.mini-batch.size", "5000"); // the maximum number of records can be buffered by each aggregate operator task ``` It seems `Configuration` supports method chaining, while it's not true since the return type of `Configuration#setString` is Void. This PR updates the documentation to fix this. ## Brief change log - Break the chaining call of `Documentation#setXXX` ## Verifying this change This change is a trivial rework without any test coverage. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
