Getting number of vertex tasks at runtime
Hi,
A Processor can read its task index via getContext().getTaskIndex().
Is there a way to similarly get the total number of tasks scheduled for
this vertex?

Hi,
The getContext().getVertexParallelism gives you the total number of
tasks. is that what you are looking for?

Hello Kostas,
0.5.0 is released and should be available on the apache releases maven repo.
There should likely be a 0.5.1 release at some point in the near future with various bug fixes.
As for 0.6.0-SNAPSHOT, we are adding features and bug fixes to this but it should be compatible with 0.5.0.
thanks
