NoSQLight

Small easily embeddable Document Oriented DB for everyday use.

Think about it as about NoSQL version of SQLite.

Requirements

• Open Source - BSD, MIT will be the best
• Multiarch (x86, amd64, arm at least)
• Self-contained - It requires very minimal support from external libraries or from the operating system.
• Serverless - database reads and writes directly from the database files on disk. There is no intermediary server process.
• Zero-Configuration -
  • DB does not need to be "installed" before it is used.
  • There is no "setup" procedure.
  • There is no server process that needs to be started, stopped, or configured.
  • There is no need for an administrator to create a new database instance or assign access permissions to users.
  • DB uses no configuration files.
  • Nothing needs to be done to tell the system that DB is running.
  • No actions are required to recover after a system crash or power failure.
  • There is nothing to troubleshoot.
• Document Oriented
• JSON Based - no XML, please
• Small resource footprint
• Simple Clean API for at least inserting and simple querying
• Native Implementation (C/C++)
• Easy to Wrap for using in other languages (python, nodejs, ruby, java, c#, )
