Implement MyriaL support for MyriaX `Split` operator #529

Closed senderista closed 8 years ago

senderista commented 8 years ago

The Split MyriaX operator (splits string values on a regex) has been around for a while but has no support in Raco. We need to add a simple functional syntax to use it in MyriaL. (Eventually both the operator and the syntax will be superseded by a proper flatmap UDF design.)

Can you list a tiny example of what such a plan looks like? Does it assume the input is a relation of 1-arity string type?

This was superseded by SplitExpression (https://github.com/uwescience/raco/pull/537).
