About
Chronicle Map is a super-fast, in-memory, non-blocking, key-value store,
designed for low-latency, and/or multi-process applications such as
trading and financial market applications. See Features
doc for more information.
The size of a Chronicle Map is not limited by memory (RAM), but rather
by the available disk capacity.

Why use Chronicle Map?

and network failures. The map can optionally be persisted to disk. -
