Aerospike has released version 5.5, which introduces XDR Convergence support. This feature prevents concurrent updates from causing bin values to become out of sync indefinitely by using a conflict detection and resolution strategy based on last-update-time (LUT) and source id (src-id). Aerospike 5.5 also includes minor features such as the ability to specify multiple feature key files, new duplicate resolution statistics, support for boolean values in maps & lists, and systemd startup script improvements.
