Thanks for this but what concerns me is if i setup several data regions and
one of them happens to be a play area i guess for data scientists and they
hit the memory limit of that region then the whole server goes down. in the
case for a cluster all the nodes hosting that region will go down. I
Hi Wayne,
You can see a message written to a console during Ignite startup with
a calculated amount of memory required for a server. It looks as follows:
Nodes started on local machine require more than 80% of physical RAM
what can lead to significant slowdown due to swapping (please decrease

in testing i managed to exceed a data regions space and this region is memory
only. When this happens an unhandled exception is thrown from the underlying
