<div dir="ltr">Hi,<br><div class="gmail_extra"><div><br style="font-family:'arial black',sans-serif">Thanks everyone for their time to reply on this post.</div><div><br></div><div style>Anil, TCP/IP sockets are slow(not really actually) compared to erlang message passing in an erlang cluster. The more important thing is if I use erlang message passing and other distributive features of the language, it will avoid writing the code myself, will be more fault tolerant and more reliable to use. As I cannot do everything in erlang, I am using node.js on the front end side (erlang is on back end side). My application is running in a cluster where any server may have to talk to other for information, I thought that doing the nodejs to erlang communication locally and use message passing among the nodes in the cluster will be better.</div>

What is the most efficient way to pass events/data from erlang processes to nodejs and vice versa? Setting up a tcp socket may be slower or inefficient. I was thinking of doing something native. Both erlang and nodejs provide libraries(NIF) to call C functions but none of them provide an efficient implementation for calling erlang/nodejs functions from C or C++ as far as I know. Please suggest some ideas!</div>
