----------------------------------------
pnowojski opened a new pull request #6744: [FLINK-10379][docs,table] Fix Table
Function docs
URL: https://github.com/apache/flink/pull/6744
This is a simple documentation fix for Java Table API.
Old syntax of joining with Table Functions in Java Table API:
```
// Register the function.
tableEnv.registerFunction("split", new Split("#"));
myTable.join("split(a) as (word, length)");
```
is no longer supported and this the reason why the documentation needed to
be updated. Currently supported syntax is:
```
orders.join(new Table(tEnv, "split(a)");
```
