Milinda Lakmal Pathirage updated SAMZA-483:
-------------------------------------------
Attachment: SAMZA-483-6.patch
[~criccomini], I was using ./gradlew build previously. But I tried
{noformat}bin/check-all.sh{noformat} and it worked even though couple of out of
memory exceptions during tests. I am using a mac and I had to install JDK 1.6
to use check-all.sh. But when I did that, I had to remove some @Override
annotations due to JDBC API differences in Java 1.6.
This new patch contains the changes.

> Per discussion with [~criccomini] and [~milinda], we agreed that it seems to
> be a good idea to define a common representation of relational algebra on top
> of the operators defined in the operator layer (see SAMZA-482), which can be
> the common base that we can use to generate the description/configuration of
> a Samza job.
> This common layer can also be used by DSL-like language parser as a result of
> parsing a DSL program.
> Some additional requirements needed in addition to pure relational algebra:
> 1) the common representation should include window operators and stream
> operators (i.e. IStream/DStream/RStream)
> 2) the common representation should include description on parallelism of the
> jobs (i.e. how many partitions the resultant Samza job will use)
