Expand description
A delta query stage performs a stream lookup into an arrangement.
Fields
lookup_relation: usize
The relation index into which we will look up.
stream_key: Vec<MirScalarExpr>
The key expressions to use for the streamed relation.
While this starts as a stream of the source relation, it evolves through multiple lookups and ceases to be the same thing, hence the different name.
stream_thinning: Vec<usize>
The thinning expression to apply on the value part of the stream
lookup_key: Vec<MirScalarExpr>
The key expressions to use for the lookup relation.
closure: JoinClosure
The closure to apply to the concatenation of columns of the stream and lookup relations.
