Editor's Notes
Complex event processing involves the processing and querying of data when the data is in flight. The data needs to be processed before there is time to persist it.Such processing involves very high data rates and often deals with multiple concurrent event sources and multiple output data.The aim is to process with as little latency as possible.
Slide ObjectiveSQL Server “Denali” AlwaysOn can give you many advantages, including the ability to failover entire applications, easier setup, multiple failover targets, and remote failover.Speaker ScriptSQL Server “Denali” makes high availability and disaster recovery much easier to set up and maintain. With the new availability groups, you can:Have a database and dependent objects fail over as a unit, so you do not have to manually duplicate changes from the master server to the failover servers. This decreases the effort to maintain the system and increases uptime.Provide faster failover for reduced downtime. Failover now is in the order of one minute, down from multiple minutes.Define a failover policy so you can fail to different servers. This lets you reduce the amount of hardware that is sitting idle waiting for a server to fail as well as providing options for local and remote failover.Provide up to four secondary servers. Two are synchronous servers (up-to-date mirroring), with the others being asynchronous (some latency with log shipping).In addition, many operations that used to lock users out of the server now can be performed online, so you do not have to schedule as many maintenance windows.Finally, with support for running SQL Server “Denali” on Windows Server Core, you can reduce the number of operating system patches to increase data availability.
