HDB++
Description
The Tango archiving system is a tool allowing Tango users to store the readings coming from a Tango based control system into a database. The archived data are essential for the day to day operation of complex scientific facilities for instance. They can be used for long term monitoring of subsystems, statistics, parameters correlation or comparison of operating setups over time.
To take advantage of the fast and lightweight event-driven communication provided by Tango release 8 with the adoption of ZeroMQ, a novel archiving system for the Tango Controls framework, named HDB++, has been designed and developed. This began as a collaboration between Elettra and ESRF.
HDB++ design allows Tango users to store data with microsecond timestamp resolution into traditional database management systems such as MySQL or into NoSQL databases such as Apache Cassandra.
