A new book on MySQL Cluster is out. It is called MySQL Cluster 7.5 inside and out.
It is on its way out to all internet sites. Currently it is accessible on adlibris.se and on

Dear MySQL users,

MySQL Router 8.0.4-rc is the first release candidate for MySQL Router
8.0 series.

The MySQL Router is a new building block for high availability solutions
based on MySQL InnoDB clusters.

By taking advantage of the new Group Replication technology, and
combined with the MySQL Shell, InnoDB clusters provide an integrated
solution for high availability and scalability for InnoDB based MySQL
databases, that does not require advanced MySQL expertise.

The deployment of applications with high availability requirements is
greatly simplified by MySQL Router. MySQL client connections are
transparently routed to online members of a InnoDB cluster, with MySQL
server outages and cluster reconfigurations being automatically handled
by the Router.

To download MySQL Router 8.0.4-rc, see the “Development Releases” …

MySQL query cache is a query caching mechanism – deprecated as of MySQL 5.7.20 and removed in MySQL 8.0 – on top of MySQL itself (based on the official MySQL documentation).
