> I'm developing a streaming pipeline with big memory consumption in one of the
> PTransforms.
> After some period after starting this pipeline fails without any specific
> logs (see attachment file)
> It looks like, that it happens because of OutOfMemory.
> It would be great to set a limit of threads that will be used in a single
> worker to control memory load.
> I found such option in JAVA SDK (--_numberOfWorkerHarnessThreads_), but in
> Python SDK it is absent
