HD Memory

Why HD Memory?

• It’s easy to scale Hazelcast horizontally for compute and memory storage.

• Just add more JVM.

• This works for the majority of use cases.

Why HD Memory?

• But, what if you want a cluster with Terabytes of data?

• If the box has hundreds of GB memory?

• Too scale this way puts pressure on cores.

• JVM Heap will give large pauses if made too large ~10gb

HD Memory

• What of you could scale horizontally and vertically?

• Have fewer JVMs, but access all the memory on the machine.

• This is what Hazelcast Enterprise HD Memory gives us.

HD Memory

• HD Memory allows a JVM to address memory on the native OS.

• This means no more long GC pauses.

• Create a small JVM Heap of 512mb and it can access hundreds GB of native memory.
