> The PutKudu processor property "Kudu Client Worker Count" has a suboptimal
> value. Please don't use the current "number of CPUs multiplied by 2"
> behaviour as it leads to a massive amount of workers in our case with
> physical servers. We have a 8-node cluster where each server has 64 CPUs. We
> have about 30 PutKudu processors configured -> a lot of worker threads per
> default just for kudu.
> We have changed the number of worker threads in our case to the number of
> concurrent tasks. I don't know, maybe it would be great to set it a bit
> higher than that, but to be honest, I don't exactly understand the impact. It
> looks still fast with the current config.
> *To sum it up, please set a low default value (eg. 4 or 8) for the property
> "Kudu Client Worker Count" and not a pseudo dynamic one for the PutKudu
> processor.*
> Btw. are there any suggestions how big the number should be?
