Upgrade to Aerospike Database 5.0

Detailed here are the major improvements and changes in Aerospike Database 5.0.

Must first upgrade to version 4.9 before 5.0​

Before upgrading to Aerospike Database 5.0, you must first upgrade to version 4.9.

Version 4.9 is a required step-version upgrade that makes important changes in preparation for upgrading to 5.0.

For more information about version 4.9, see the Release Notes.

Configuration parameters that must be removed​

See this list of configuration parameters that are no longer allowed in the configuration file.

Aerospike Database 5.0 will not start unless you remove them.

Improvements in Cross-Datacenter Replication (XDR)​

The XDR feature has been redesigned for improvements in speed and simplicity.

See the following for complete details on XDR for version 5.0:

Change in XDR stanza structure​

An important syntactical change in configuration parameters for XDR version 5.0 is that the xdr stanza is now simpler and more logical, with parameters in a hierarchy that is clearer than before.

The basic XDR stanzas for pre-version 5.0 and for version 5.0 are compared below. Only the basic structure is described, without any optional parameters.

  • enable-xdr is not needed.
  • XDR no longer relies on a digest log.
  • IP address and port can be followed by an optional variable reference of a TLS certificate, instead of the tls-node parameter.
  • The namespace sub-stanza is nested under the dc sub-stanza, instead of referring to the main `namespace` stanza that used to include the XDR-related configuration.
Pre-version 5.0
xdr {
   enable-xdr true
   xdr-digestlog-path /opt/aerospike/xdr/digestlog 100G
   datacenter DC1 {
      dc-node-address-port xx.xx.xx.xx 3000
      tls-node yy.yy.yy.yy tlsname.remote.domain 3010
   }
}
namespace test {
   enable-xdr true
   xdr-remote-datacenter DC1
     ... 
}
Version 5.0
xdr {
  dc dataCenter1 {
    node-address-port someIpAdress1 somePort1 someTlsNameDefinition1
    namespace someNamespace {
       ...
    }
  }
 ...
}
