Support Board

We require that your protocol definition file compiles under Google protocol buffer version 3.

We have to use Google protocol buffer version 3 compiler and library because we use other Google protocol buffer implementations which require that.

The protocol definition file you linked to here does not compile under Google protocol buffer version 3 compiler.

You do not have to on your server itself support Google protocol buffer version 3. You just need to have another version of your protocol definition file which will compile under version 3. It still will be the same but just some minor changes are needed.

As long as the overall structure of the messages is the same, the underlying encoding will remain the same. We know that from experience and that is what is documented in the Google protocol buffer documentation. So it is not a problem to provide support for version 3. The underlying encoding will be the same.

This is important for us because we are using an older CQG Web API definition file and we are wondering if this is what is leading to missing data for our users with the real-time market data. We have many reports of that.
