The TANGO release 8 led to several enhancements, including the adoption of the ZeroMQ library for faster and lightweight event-driven communication. Exploiting these improved capabilities, a high performance, event-driven archiving system written in C++ has been developed. It inherits the database structure from the existing TANGO Historical Data Base (HDB) and introduces new storage architecture possibilities, better internal diagnostic capabilities and an optimized API. Its design allows storing data into traditional database management systems such as MySQL or into NoSQL database such as Apache Cassandra. This paper describes the software design of the new HDB++ archiving system, the current state of the implementation and gives some performance figures and use cases.
