Special upgrade to Database 5.0.0

This page describes the major improvements and changes in Aerospike Database 5.0.0.

Database 4.9.0 is required

Before upgrading to Aerospike Database 5.0.0, you must first upgrade to Database 4.9.0, which is a required step-version upgrade that makes important changes in preparation for upgrading to 5.0.0.

For more information about version 4.9.0, see the Release Notes.

Cross-Datacenter Replication (XDR) improvements

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

See the following for complete details on XDR for version 5.0.0:

Change in XDR stanza structure

An important syntactical change in configuration parameters for XDR version 5.0.0 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 5.0.0 and for version 5.0.0 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.

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
     ...
}

xdr {
  dc dataCenter1 {
    node-address-port someIpAdress1 somePort1 someTlsNameDefinition1
    namespace someNamespace {
       ...
    }
  }
 ...
}
