Hello, I'm using Node Cluster and mongoDB native driver.
I have 4 Workers+ running on the nodeJS application.

My question is regarding the mongoDB client(connection instance). I have a mongoController class that starts and configures the mongodbClient instance with the connection pool, althouth node cluster creates a new process for each processor's core(fork), therefone we will have one mongoController for each worker, so each worker will have its own mongoDB client and connection pool.
I don't think this is the best approach/architecture to implement, I would like to have just one mongoController singleton class on the master process that is responsible for managing the mongoDB client and connection pool through events using ipc messages. To be able to implement that I need to serialize the mongoDB connection instance and send it via IPC messages to all the workers that need to use the mongoDB connection instance. I don't know yet how I could serialize the mongoClient and the connection instance and send it to workers using the nodeJS "cluster.send" interface.

Thank you!
