Remarks

This operator is stateless. As such, it can be a more efficient alternative to the Union(CollectionTRecord, TTime) operator, when precise multiplicities are not important (e.g. because the output feeds into a Distinct, AggregateTKey, TValue, TOutput(ExpressionFuncTRecord, TKey, ExpressionFuncTRecord, TValue, ExpressionFuncInt64, TValue, TValue, TValue, ExpressionFuncTValue, Boolean, ExpressionFuncTKey, TValue, TOutput), or similarly idempotent operator).
