Assembly: Microsoft.Research.Naiad.DifferentialDataflow (in Microsoft.Research.Naiad.DifferentialDataflow.dll) Version: 0.5.0.0 (0.5.0.0)

Parameters

other

Type: Microsoft.Research.Naiad.Frameworks.DifferentialDataflowCollectionTRecord, TTime
The other collection.

Return Value

Type: CollectionTRecord, TTime
The collection containing the multiset union of the two input collections.The multiset union contains each record in either this collection or the other collection. For each record in either collection, the multiplicity of that record in the multiset union will be the greater of its multiplicities in either collection. The union operator is stateful. If 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), the Concat(CollectionTRecord, TTime) operator is a more efficient substitute.
