Data Operations
Transform data with filters, joins, aggregations, and 27 other operations.
Runs a saved chain of data operations over one or more frames.
The older, general-purpose transform node: operations is an ordered list the data-operations engine executes. For new flows the Primitives — Select, Filter, Join, Aggregate and the rest — say the same thing one step per node, which the builder can typecheck and the reactive tier can memoize per step.
