Sergey, The issue vanishes as soon as I add the following to the configuration:
<property name="memoryConfiguration"> <bean class="org.apache.ignite.configuration.MemoryConfiguration"> </bean> </property> My point is that we just need to create a MemoryConfiguration implicitly if it’s not defined (no any warnings or extra messages). It’s a responsibility of our platform to generate a default configuration if it’s not set explicitly. — Denis > On May 26, 2017, at 8:46 AM, Sergey Chugunov <sergey.chugu...@gmail.com> > wrote: > > Hi Denis, > > What is the expected behavior in that case?
