Hi, As per java doc of DataRegionConfiguration.setMaxSize - maxSize Maximum data region size in bytes. For sure, it won't work properly with such a small memory size(128 and 1024 bytes). Ignite even have validation for this parameter and it should be not less than 10mb at least.
Have you checked your logs? Do you have any exceptions? Have you checked thread dumps? Where was it hanged? Regards, Evgenii -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
