GroupingDataflowBlockOptions GroupingDataflowBlockOptions GroupingDataflowBlockOptions GroupingDataflowBlockOptions Class

Definition

Provides options used to configure the processing performed by dataflow blocks that group together multiple messages. These are dataflow blocks such as JoinBlock<T1,T2> and BatchBlock<T>.

Remarks

Note

The TPL Dataflow Library (the System.Threading.Tasks.Dataflow namespace) is not distributed with .NET. To install the System.Threading.Tasks.Dataflow namespace in Visual Studio, open your project, choose Manage NuGet Packages from the Project menu, and search online for the System.Threading.Tasks.Dataflow package. Alternatively, to install it using the .Net Core CLI, run dotnet add package System.Threading.Tasks.Dataflow.

GroupingDataflowBlockOptions is mutable and can be configured through its properties.

When specific configuration options are not set, the following defaults are used:

Options Default
TaskScheduler Default
CancellationToken None
MaxMessagesPerTask DataflowBlockOptions.Unbounded (-1)
BoundedCapacity DataflowBlockOptions.Unbounded (-1)
MaxNumberOfGroups GroupingDataflowBlockOptions.Unbounded (-1)
Greedy true

Dataflow block capture the state of the options at their construction. Subsequent changes to the provided GroupingDataflowBlockOptions instance should not affect the behavior of a dataflow block.

Constructors
