Subject off heap question
Date Sun, 04 Jun 2017 06:21:00 GMT
Hi Everyone, 

Does one here already tried or worked with off heap feature and not just small check, a wide
check with many objects? 

I am wondering regard those who wrote or already using the off heap feature way of work. 
It seems that there isn't any external or 3rd party framework that being used, it seems that

It is working by allocating X size of memory for this storage and by using sun unsafe.

(Why I am wondering?
Since as far as I remember oracle plan is to remove unsafe from java at version 9. Named as
JEP 260. 
After small check I can see that they leave it on java 9 with recommendation to replace usage
with VarHandle instead.)

I am trying to compare and understand deeply the off heap implementation here for example
in comparison to apache ignite.
