db_wrapper

What is db_wrapper ?

db_wrapper is a Ruby gem that allows the creation of listeners to every database call you make in a transparent way.

How does it work ?

It creates a super lightweight TCP proxy that will redirect every database call to the proxied database (in a non blocking way) to another process that will call the listeners you registered. Everything happens in a different process so the listeners won't impact the database query performance.

The fact that it works like a proxy allows you to create listeners without changing your application code and without needing to worry about performance.

Which databases does it support ?

  • Mysql
  • PostgreSQL (future)
  • MongoDB (future)

The protocol implementation is simple so you can easily extend it by yourself to support a different database (and send me the pull request if you want)

Next steps

  • PostgreSQL protocol
  • MongoDB protocol
  • Examples and documentation
  • Server listeners - Listeners that would get data sent from the server to the client, also in a non blocking way
