Using MySQL with memcached memcached is a simple, highly scalable key-based cache that stores data and objects wherever dedicated or spare RAM is available for quick access by applications, without going through layers of parsing or disk I/O. ...
Using MySQL within an Amazon EC2 Instance The Amazon Elastic Compute Cloud (EC2) service provides virtual servers that you can build and deploy to run a variety of different applications and services, including MySQL. The EC2 service is based around the Xen
Using Namespaces The memcached cache is a very simple massive key/value storage system, and as such there is no way of compartmentalizing data automatically into different sections. For example, if you are storing information by the unique ID ...
Using Replication for Backups To use replication as a backup solution, replicate data from the master to a slave, and then back up the data slave. The slave can be paused and shut down without affecting the running operation of the master, so you can produce an effective snapshot of “live” data t...
Using Replication for Scale-Out You can use replication as a scale-out solution; that is, where you want to split up the load of database queries across multiple database servers, within some reasonable limitations. Because replication works from the distribution of one master to one or more slav...
Using Replication with Different Master and Slave Storage Engines It does not matter for the replication process whether the source table on the master and the replicated table on the slave use different engine types. In fact, the default_storage_engine [489] and storage_engine [561] system varia...
Using the Administration Interface The mysql-proxy administration interface can be accessed using any MySQL client using the standard protocols. You can use the administration interface to gain information about the proxy server as a whole - standard connections to the proxy are isolated to opera...
Using the memcached TCP Text Protocol Communicating with a memcached server can be achieved through either the TCP or UDP protocols. When using the TCP protocol, you can use a simple text based interface for the exchange of information. When ...
Using ZFS Replication To support high availability environments, providing an instant copy of the information on both the currently active machine and the hot backup is a critical part of the HA solution. There are many solutions to this problem, including Chapter 16, Replication and Section 15.2...
Wait Event Consumers These consumers require both global_instrumentation and thread_instrumentation to be YES or they are not checked. • events_waits_current, if NO, disables collection of individual wait events in the events_waits_current table. If YES, it enables wait event collection and the ...
