Hi Kristian,
I couldn't find an example of join with the Java scala-like API but there is:
- An example using the pure Java API
here:incubator-wayang/WayangPlansOperators.java at main ·
apache/incubator-wayang

incubator-wayang/WayangPlansOperators.java at main · apache/incubator-wa...
Apache Wayang(incubating) is the first cross-platform data processing system. -
incubator-wayang/WayangPlansOper...

- An example using the scala API (thus the PlanBuilder)
here:incubator-wayang/Query3Hybrid.scala at main · apache/incubator-wayang

I hope these are useful. Let us know if you encounter any issue with the
JavaPlanBuilder.

Hi Zoi,
Yes, an example of an implementation of the wayang join operator. I cannot find
it in the JavaPlanBuilder. But I might be overlooking something :-)
Best,
Kristian

Emne: Re: Status on SQL API
Hi Kristian & Michelle,
regarding your "implementation of the join operator in the java API" question,
what exactly are you looking for?
Isn't there a join operator via the JavaPlanBuilder?
Or you are looking for the implementation of the join opearator using the Java
platform?

Hi Wayang Dev!
Just a quick update on the research project involving the SQL API that Michelle
and I are working on:
Due to our limited time, we are focusing on implementing:
1. The join operator (probably just the inner join)
2. Sql query from both a csv and postgres data source
We’re currently waiting for the current SQL API to be merged into the Wayang
repository. Afterwards we will be happy to contribute with our work.
We have been searching for the implementation of the join operator in the java
API, but we haven’t succeeded. So if any of you have a pointer to this, it
would be much appreciated!
Best regards,
Michelle and Kristian!
