Avoid XDR compression errors with Database 4.8.x or later

Overview​

This page describes how to upgrade Database 4.3.x or earlier to avoid XDR compression errors with Database 4.8.x or later.

In an XDR system with compression enabled, records cannot ship from a cluster running Database 4.8.x or later to a destination cluster running Database 4.3.x or earlier. The solution is to keep the version on the source cluster from getting ahead of the version on the destination cluster. Consider upgrading all clusters to Database 4.9.x which is a required jump-version that makes important changes in preparation for upgrading to Database 5.0.

  • When your system ships in one direction from a source cluster to a destination cluster, and both are running Database 4.3.x or earlier, upgrade the destination cluster to Database 4.9.x. Upgrading the source cluster is optional. If you and you upgrade the source cluster to Database 4.8.x or later while the destination cluster is still running Database 4.3.x or earlier, you will see error messages in the logs.

  • When your system has compression enabled and ships records back and forth between clusters running Database 4.3.x or earlier, upgrade in stages. Upgrade one cluster to the highest Database 4.7.0.x version, then upgrade the other cluster to Database 4.9.x. Upgrading the Database 4.7.x cluster is now optional.

Aerospike does not recommend disabling compression because of the effects it can have on your network. If you choose to disable compression, however, see Decompression fails on old XDR.

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

For information about upgrading from Database 4.9 to Database 5.0, see Upgrade to Aerospike Database 5.0.
