KVDB - Database Management System for Connected Device Management

KVDB was initially designed to support the requirements of the Exosense system for managing Connected Devices, but is essentially a general-purpose DBMS. A requirement was that it should be useable both in an embedded device and on the device management server. To this end, KVDB supports a number of different storage backends, each with different characteristics.

Features:

• Ordered-set semantics

• Transaction semantics

• Persistent queues

• CRON-like persistent timers

• Extensible indexing

• Storage backend plugins

• Schema callback behavior
