Inherited from Any
A query interpreter for MemoryProfile and for client-side operations that need to be run as part of distributed queries against multiple backends.
It uses ScalaType, ProductValue/StructValue and plain Scala collections to represent data. Queries are expected to be in the shape after running all the standard query compiler phases (but not the extra relational phases) and assigning ScalaTypes everywhere.
