@marsupialtail_2 @neelesh_salian @LinkedInEng @Captaintobs Coral has 2 equivalent IRs, one at the AST layer and another is at the logical layer (it does not deal with the physical layer). I think that makes it pretty flexible yet powerful and robust. More details in the slides @neelesh_salian shared.

@joe_hellerstein @julianhyde There is basic support of recursion (no negation or aggregation). Implementing relational algebra front ends is straightforward (e.g., Pig Latin, SPARQL, Datalog). See relevant Datalog discussion here: https://t.co/0VEFr1U3rc. Would love to explore linear algebra extensions.
