Re: Python and Scala

[Piotr Nowojski]

Hi,

I have never used it before, but it’s described in the documentation:

https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/scala_shell.html
 
<https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/scala_shell.html>

the "Adding external dependencies” part. It should answer to this question.

Hi

Good news. Is it way to supply Scala-code from file to REPL ?

It seems the compiling is too complicated operation.. Actually I don’t get it 
to work yet.

Hi

Scala REPL uses the same code as compiled library so they should work the same.

Hi,

1. Flink’s Python Batch API is not complete and it’s not on pair with Scala.
2. As for know there is no Python API for Flink Streaming, however there is 
some ongoing work with that: https://issues.apache.org/jira/browse/FLINK-5886
3. CEP doesn’t work with Flink Batch, you have to use Flink Streaming for that:

Can I do all the same things with Python and Scala ? For examples CEP with 
files.

Hi

Scala REPL uses the same code as compiled library so they should work the same.

Hi

And what about the differences between Scala REPL and Scala (compiled) ?

Hi,

1. Flink’s Python Batch API is not complete and it’s not on pair with 
Scala.
2. As for know there is no Python API for Flink Streaming, however 
there is some ongoing work with that: 
https://issues.apache.org/jira/browse/FLINK-5886
3. CEP doesn’t work with Flink Batch, you have to use Flink Streaming 
for that:
