Iam trying to figure out the advantage/disadvantage between using Java vs ESQL in a compute node or (When Java fits the job better than ESQL):

I have the following 3 points:

Java Skills
Programming language necessary - (Java)
Java - Rich class library

Is there any other advantage/disadvantage of using Java vs ESQL in compute node - with respect to performance etc..,

Thanks.

From what I have heard you pay a higher (performance) price entering and leaving a java compute node than when entering and leaving an (ESQL) compute node.

So if you can limit yourself to one (java) compute node per flow you might even be faster...

Enjoy

many things that are very easily done in ESQL take a lot of coding in Java .
Those things are better left to ESQL .. For things that are not possible/hard in ESQL , in most cases java provides a very easy solution ...

Performance i am not able to comment on ..but a mix of ESQL + Java provides a very comfortable and fast development cycle in most cases.
Just my experience..
