Hi,
it is true that there is no dedicated machine learning library for
Flink. Flink is a general data processing framework. It allows to
embedded any available algorithm library within user-defined functions.
Flink's focus is on stream processing. There are not many dedicated
stream processing algorithms out there. Usually, people run batch jobs
to train models and just evaluate the model in independent parallel
operator instances.
There are some ML efforts going on and I'm sure there will be more in
the future. But for now the community focuses on developing a very good
streaming runtime core.

I hope this helps a bit.

Hello
I am a complete newbie and I need help. I am evaluating the usage of
flink for my academic study and reading the documentation. I have a bit
of experience in Apache Spark. I am asking this question, based on my
experience in Apache Spark.
In spark, there is a machine learning library embedded in the
framework. To the best of my knowledge, the library is aware of RDD
data structure and the machine learning algorithms do get benefits of
cluster processing. I have read about flink cluster capability but I
have not seen a machine learning library for flink. I have seen some
references of machine learning library for flink in google searches but
they are linked to older versions of flink. It seems machine learning
library has been dropped from the flink in latest releases.
My questions are;
1. Is it true that there is no customized machine learning library for
flink or I am missing something?
2. If there is no customized machine learning library for flink, what
are my options? Can I use any library which uses scala or java api?
3. If I use an external machine learning library, how this will impact
cluster processing of flink. Does the processing of algorithms become
bound to one flink instance? How can the algorithm be scaled, multiple
machines?
I appreciate any response, please respond me gently, like a talking to
a kid....I am really newbie...
Thank in advance...
