In version 1.2 the focus continues to be on supporting MySQL database clusters
|
||||
with asynchronous replication. The plugin tries to make using the cluster
|
||||
introducing a quality-of-service filter which applications can use to define
|
||||
what service quality they need from the cluster. Service levels provided are
|
||||
eventual consistency with optional maximum age/slave slag, session consistency
|
||||
and strong consistency.
|
||||
</para>
|
||||
<para>
|
||||
Additionally the plugin can do client-side global transaction id injection
|
||||
to make manual master failover easier.
