CoralStore can write a 256-byte message to disk in around 159 nanoseconds through the FileStore implementation. Moreover, by using the AsyncStore you can get even lower latencies (60 nanoseconds) and variance, as the numbers on this article demonstrate.  Continue reading

                                CoralStore is a read/write message store backed up by in-memory and in-disk implementations. It supports sequential asynchronous writes through a lock-free queue for ultra-low-latency persistency of 60 nanoseconds on average per message with 256 bytes in size.
