Milinda Lakmal Pathirage commented on SAMZA-482:
------------------------------------------------
I like the way Hive is handling nested data structures and Hive's DDL. Hive
uses ObjectInspector [2] to handle nested data structures [1]. We can try to
reuse Hive's implementation, at least a part of it. May be we can wrap Hive's
DDL and SerDe implementation. I am not sure whether this is the best approach.
But I am sure if we can reuse, it will save us considerable amount of time.

> 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).
