# Flink Array Row Bug

This is a reproducer of a bug reported in [FLINK-28591](https://issues.apache.org/jira/browse/FLINK-28591).

## How to reproduce

Run

```shell

mvn clean install exec:java -Dexec.mainClass=com.github.swtwsk.FlinkArrayRowBugJob

```

and `cat` the file that got generated (named `part-...`).

---

Although in the INSERT we tried to insert

```roomsql

array[

    ('Field1', 'Value1'),

    ('Field2', 'Value2')

]

```

in the JSON that got printed to the generated file we get duplicate of the last inserted row:

```json

"bar": [

  {"foo1":"Field2", "foo2":"Value2"},

  {"foo1":"Field2", "foo2":"Value2"}

]

```
