LinkedIn is perhaps not known for their development efforts in the open source community.
But to my surprise, they have released an open source data store, dubbed “Sensei DB” which I find really interesting. (They may in fact have released it a while ago, but I just recently have discovered it)
- It’s built for high reliability, fault tolerance and scalability
- The main uses are for full text search, key value store and realtime updates
- It includes a new query language, very similar to SQL, which they call BQL, or “Browse Query Language”
All in all it looks pretty interesting.
