Aerospike Server (May 14, 2020)

Aerospike Server version was released on May 14, 2020.

This major release contains a New Feature, and Improvements.

  • If using XDR, it is strongly advised to upgrade to version or above. Refer to AER-6231 and the release notes for details.
  • The Cross-Datacenter Replication (XDR) feature has been redesigned for improvements in speed and simplicity. Refer to:
  • Cross-Datacenter Replication (XDR) running in Aerospike Server version 5.0 can only connect to XDR destination clusters running versions 4.1 or newer.
  • All nodes must be upgraded to Aerospike Server version or newer prior to upgrading to Aerospike Server version 5.0.
    • Aerospike Server version 5.0 will not form a cluster with version 4.8 nodes or earlier.
    • When upgrading the Aerospike Server refer to the Special Upgrades documentation.
  • The Aerospike Server will not start if obsolete configuration parameters are set in the Aerospike configuration file (aerospike.conf).
  • The maximum cluster size is now increased to 256 nodes. However, the actual limit when using multicast heartbeat mode will depend on the Maximum Transmission Unit (MTU).
    • There is a 132 node limit with MTU of 1500. A 256 node limit can be achieved with an MTU of 9000.
  • ATTENTION: As of Aerospike Server version 4.9, expirations and evictions are disabled by default.
  • XDR, using ACL, in server versions between and cannot ship to this version. The simplest workaround is to avoid using those versions.
  • Community Edition clusters now limit the maximum amount of data to 5TB of unique data. Refer to:
  • Please reach out to your account representative if you are interested in Kerberos support.
