mongo-proxy

A multi-tenancy mongo-proxy consolidating multiple physical clusters

Architecture

client  ->   handleFuncChain [HandleCommand   ----> Transform]
                               |                    |
    <--------------	    block and process      has response? ---> mongo
                                                    | Y              |
    <---------------------------------------     return              |
                                                                     |
    <---------------------------------------     revert     <--- response

• Authentication and handshake would be blocked and processed by mongo-proxy.
• A meta server is employed to help mongo-proxy to route connections and requests.
• Necessary transformations would be applyed to requests and responses to shield the topology of physical clusters.

Modules

Wire

Parser of mongodb wire protocal

Topology

Connection and endpoint implements.

Proxy

Transformations and router of request and response

Meta

Topology of physical clusters. Only mongodb suppoerted currently.

Operation

Commands that should be processed locally, such as ismaster, handshake.

Auth

Sasl authenticator handler. Only SCRAMSHA256 supported currently.
