pdb - MySQL and Postgres sharding proxy **** IMPORTANT **** This work is not complete or maintained! The most similar ative project that I'm aware of is spock proxy, which is over here: http://spockproxy.sourceforge.net/ Description =========== pdb intends to be a proxy which hides the details of a "sharded" database from application/SQL developers. That is, application developers continue to write their code as if there were just a single monolitic database. pdb translates and proxies the application's requests to the appropriate shard(s), in parallel if possible, and marshalls the responses back to the application. Current state: . mysql protocol reverse-engineered . connection and non-query command proxying to mysql . basic hash-based sharding logic . 'update' queries shard correctly
