Ignite Xmx configuration
Hi Team,
I have two off-heap caches with 4 gb size (per cache) in my ignite node.
What would be the Xmx setting for ignite node ?
is it 2 * 4 + heap required ? or Xmx is not related to any of the cache
size ? please clarify. thanks.
Regards
Anil

Indexes does not include in it. Indexes will occupy extra size.

Hi Nikolai,
One more question- documentation says the indexes are stored in off heap as
well for off-heap cache?
where does it store ? in the same 4 g (in my case) ? thanks.
Regards,
Anil

Hi!
If you used off-heap cache then entry is not stored in heap memory. Hence
Xmx is not related with cache size. You need to choose Xmx/Xms based on
your application requirements (how many object will be created by your
code). I guess that 2-4 Gb will be enough in your case.
