Hi Ken,
Thanks for your reply.
As I said before, we try to reuse Flink's state concept (fault tolerance
and guarantee "Exactly-Once" semantics). So we did not consider cache.
In addition, if we use Flink's state, the OOM related issue is not a key
problem we need to consider.
Best,
Vino

Hi all,
Cascading implemented this “map-side reduce” functionality with an LLR cache.
That worked well, as then the skewed keys would always be in the cache.
The API let you decide the size of the cache, in terms of number of entries.
Having a memory limit would have been better for many of our

Hi Richard,
Schema evolution for data types that are used as keys is not allowed
because, potentially, if the schema of the key changes, hash codes of keys
may also change and can break partitioning for internal state managed by
Flink.
There are of course some evolution scenarios that would not re
Hi Richard,
I've pulled in Gordon who worked on this feature. He should be able to tell
you about the current limitations of Flink's schema evolution.

Hi,
Some portion of the code could be migrated to the new Table API no?
I am saying that because the new API design is based on scikit-learn and
the old one was also inspired by it.

Hi Piotr,
The localKeyBy API returns an instance of KeyedStream (we just added an

Users can call all the APIs(especially *window* APIs) which KeyedStream

So if users want to use local aggregation, they should cal

Hi,
+1 for the idea from my side. I’ve even attempted to add similar feature quite
some time ago, but didn’t get enough traction [1].
I’ve read through your document and I couldn’t find it mentioning anywhere,
when the pre aggregated result should be emitted down the stream? I think

And true, instead of overloading one of the metric it is better when user can
choose to provide only one of them.

Hi all,
As we mentioned in some conference, such as Flink Forward SF 2019 and QCon
Beijing 2019, our team has implemented "Local aggregation" in our inner
Flink fork. This feature can effectively alleviate data skew.
Currently, keyed streams are widely used to perform aggregating operations
