OStore (Ordered-Store) is a new software system for storing and processing big data.
- At its core is a NoSQL database.
- It is written in Scala and makes extensive use of Akka actors.
- Keys are stored in sorted order rather than hashed.
- It supports continuous incremental map-reduce.
OStore is curently in the early stages of development and not suitable for production use. Parts of the code are still very rough. It contains bugs and is missing lots of features. APIs will probably change in non-upward compatible ways. Error detection and recovery is partially missing. The overall system has not been fully tuned for performance.
The OStore code is licensed under the Apache 2.0 license.
You can use the github issues feature to report bugs or ask questions.
