Summary: Using Types.LIST(Types.STRING()) in datastream result in
crash
Key: FLINK-22953
URL: https://issues.apache.org/jira/browse/FLINK-22953
Project: Flink
Issue Type: Bug
Components: API / Python
Affects Versions: 1.13.1
Environment: python==3.7.5
flink==1.13.1
Reporter: awayne
In our business, we need to deserialize JSON like this:
{code:java}
{
...,
"texts": ["a", "b", "c"],
...
}{code}
number of strings in list isn't fixed.
After define Row type using Types.LIST(Types.STRING()), job will crash:
{code:java}
