Hi all,
I am writing an evolutionary computing application with Flink.
Each object is a particle with multidimensional velocity , position, and
fitness.
I create a population ( Array) of these objects and want to update
positions and velocities of all particles in parallel.
I can create the popul
Let me understand your case better here. You have a stream of model and
stream of data. To process the data, you will need a way to access your
model from the subsequent stream operations (map, filter, flatmap, ..).
I'm not sure in which case Operator State is a good choice, but I think you
can als
No that is not possible since you cannot access DataSets from inside UDFs.
And select and where operations are translated into a filter operation on a
DataSet.

Promising observation, Till. Is it possible to access Table API's
select and where operators from within such a flatMap?

Hi Nick,
I think a flatMap operation which is instantiated with your list of
predicates should do the job. Thus, there shouldn’t be a need to dig deeper
than the DataStream for the first version.

Hi All,
We have a high density data that required a downsample. However this
downsample model is very flexible based on the client device and user
interaction. So it will be wasteful to precompute and store to db.
So we want to use Apache Flink to do downsampling and cache the result for
subseque
