KVDB is a key-value database system specifically aimed at supporting NETCONF-style configuration data management, both on the server side and the device side. To this end, kvdb supports different storage backends, with different characteristics, and offers a fairly specialized API.
Some notable features:
- Transactions: currently being completed, but basically working
- Configuration data API, with support for efficiently traversing tree structures
- Flexible indexing, on single-valued or multi-valued attributes, including indexing callbacks
- Schema-based validation and event reporting, configurable per-table
- Persistent FIFO-, LIFO-, and priority-based queues
- Backends supported: leveldb and sqlite3 (both persistent), and ets (either ram-only, or persistent through transaction logging)
Among the features that remain to be implemented are:
- Distribution: while this would seem like a fundamental omission, work has been done to prepare for it
- Locking: a locking library exists, but hasn't been integrated with kvdb yet
