Chapter 2. Persistence Layer
Pure master/slave failover mechanism
The pure master/slave failover mechanism, which was previously deprecated, has been removed from version 5.8. It is recommended that you migrate such a system to use either the shared filesystem mechanism or the shared database mechanism instead.
AMQ message store
The AMQ message store is now deprecated and will be removed in a future release.
Kaha message store
The Kaha message store is now deprecated and will be removed in a future release.
Note
The Kaha message store is not the same as the KahaDB message store. The Kaha store represents an earlier generation of technology. The KahaDB message store is still supported (and recommended).
Recommended message stores
If you are using one of the deprecated message stores, it is recommended that you migrate to one of the following message stores instead:
- KahaDB message store.
- JDBC message store.
