BoJack
The unreliable key-value store
Status
Originally, from my article "Why you should build your own NoSQL Database". BoJack is a bit mature now, yet missing several important features:
- Cluster-friendliness
- Security Layer (#34)
- Unix Socket support (#48)
Feel free to share your thoughts and contribute.
