Spider and vertical partition engines with new goodies
+4 Vote Up -0Vote Down





The Spider storage engine should be already known to the community. Its version 2.5 has recently been released, with new features, the most important of which is that you can execute remote SQL statements in the backend servers. The method is quite simple. Together with Spider, you also get an UDF that executes SQL code in a remote server. You send a query with parameters saying how to …

Monitoring MySQL
+1 Vote Up -0Vote Down

Ronald Bradford wants to know what kind of Monitoring you use..
He specifically wants to know about Alerting tools

There's different cases , looking at it from a full infrastructure point my current favourite is Zabbix or good old Nagios,

But when looking at it from a debugging perspective you have MySQLAR or Hyperic, but those aren't in the alerting list.

However, when you are building HA clusters, you have custom scripts running either from mon or from pacemaker ..

Still .. Ronald probably wants more input :)

MySQL Cluster - flexibility of replication
Employee +1 Vote Up -0Vote Down

One of the better kept secrets about MySQL Cluster appears to be the flexibility available when setting up replication. Rather than being constrained to implementing a single replication scheme, you can mix and match approaches.

Just about every Cluster deployment will use synchronous replication between the data nodes within a node group to implement High Availability (HA) by making sure that at the point a transaction is committed, the new data is stored in at least 2 physical hosts. Given that MySQL Cluster is usually used to store the data in main memory rather than on disk, this is pretty much mandatory (note that the data changes are …

MySQL Proxy - what if it crashes?
Employee +2 Vote Up -0Vote Down


While I hope the MySQL Proxy never crashes, it will happen, there will be some strange (or maybe not so strange) usage or workload and it will die.

To avoid this, you could decide not to use it, or maybe you could use something like Linux HA to have more than one MySQL Proxy running at all times. Or you could use one of the new features that comes with the version 0.7.0.

What is it?
We now have a …
