Re: Off heap and JVM heap memory allocation

[akurbanov]

But please consider that you must have enough memory at least for running OS
and it's services, also Ignite would warn you if you will try to use more
than ~80% of RAM (70% in case if native persistence is enabled, and 90% if
ignite is used in the pure in-memory mode).

Best regards,
Anton

Re: Off heap and JVM heap memory allocation

Hi Akash,

You can configure ignite off-heap space as described in: 
https://apacheignite.readme.io/docs/memory-configuration
  
Just set maxSize parameter to 16L * 1024 * 1024 * 1024 for
DataRegionConfiguration.

JVM heap configuration should be defined on JVM startup using the command
line parameter -Xmx16g

Best regards,
Anton

Off heap and JVM heap memory allocation

[akash shinde]

Hi,
I have 32 GB RAM machine to configure IGNITE node. Out of this 32 GB memory
I want to allocate 16 GB for *off heap* space and remaining 16 GB for *JVM
heap* space(processing). My cache will be configured as only off heap and
JVM heap space will be use for processing.
Is there any way to do this configuration in ignite?
