@Gábor Gévay,
Thanks Gábor
I just use flink in produce environment, but the performance is not
good, especially in aggregation.
At the beginning I used Java serialization, but it does not work well.
Maybe I do not understood flink very well then. I will try change the
serialization meth
@Aljoscha Krettek,
Thanks Aljoscha, I will try this way to test the performance.
Last 7 days is chinese spring fastival, sorry for response you so late.

For example, it might help to make your type a POJO.

Hi,
You can disable those copies via ExecutionConfig.enableObjectReuse(), which you
can get from the StreamExecutionEnvironment via getConfig().
Best,
