Milinda Lakmal Pathirage commented on SAMZA-482:
------------------------------------------------
+1 for the 4 types of operators. Also +1 for the context based routing. If we
decided to distribute query execution across a set of tasks (each tasks
executing sub-query, etc.) in future, this context based routing will come
handy.

> This came out of a discussion between [~milinda], [~criccomini], and
> [~nickpan47]. We think that it will be a good idea to separate the operators
> layer from the high-level language layer, s.t. we can allow different
> languages to be built on-top-of the same set of fundamental functions (i.e.
> SQL-like or DSL).
