Elegant Way to Stop Processing a Dataflow

[dbman86]

hello, based on a condition in one of our subflows or "blocks", we would like to stop processing the current dataflow. however, we do want to re-use the dataflow for many posts so I don't think want to propogate completion for all children after. Can you think of an elegant way to do this?

thanks

from what i found, way to do this would be to use a buffer block, something like this. Do you agree or have an easier way?

var forwarder = new BufferBlock<SomeType>();
forwarder.LinkTo(target1, item => matchesTarget1(item));
forwarder.LinkTo(DataflowBlock.NullTarget<SomeType>(), item => !matchesTarget1(item));

Hi @santoorman, though this is not a DataflowEx question (but a Dataflow one), my two cents here:

Suppose you have A -> B and want to reuse B. You can basically unlink A->B and then link C->B. Unlink is supported by calling Dispose() on the return value of LinkTo() method:

Not sure whether this is what you want.
