Tatu Saloranta updated FLINK-3866:
----------------------------------
Description:
Looking at default `TypeSerializer` instances I noticed what looks like a minor
flaw, unless I am missing something.
Whereas all other array serializers indicate that type is not immutable (since
in Java, arrays are not immutable), `StringArraySerializer` has:
```
@Override
public boolean isImmutableType() {
return true;
}
```
and I think it should instead return `false`. I could create a PR, but seems
like a small enough thing that issue report makes more sense.
I tried looking for deps to see if there's a test for this, but couldn't find
one; otherwise could submit a test fix.
