ChronicleMap – Java Architecture with Off Heap Memory

My last post was written a couple of weeks ago and after some valid feedback I’d like to clarify a couple of points as a preface to this article. The main takeaway from ‘Creating millions of objects with Zero Garbage‘ should be that with Chronicle you are not ‘limited’ to using jvm allocated on-heap memory when writing a Java program. Maybe ...
