Service proxy with multiple implementations

[Marcin Czeczko]

Hi,

Does anyone have an idea, how to create service proxy having multiple implementations ?

What I mean, is to have two distinct verticles, e.g. A & B, each having it's own implementations of one service interface (and having service method void process(JsonObject, Handler handler)). 

So, in the third verticle that is about to talk with A or B, I could somehow create proxy to serviceAImpl or serviceBImpl based on some logic, e.g. depending on current configuration.

What I found is that, I can create distinct service interfaces for A & B, but when I wanted to use in the third verticle, I'd need to explicitly specify interface A or B when creating proxy.

If your are using the Service discovery this is easy. When you publish your service from verticle a or b, add metadata to the record you publish, specifying which impl this records belongs to. You need to publish your verticles at different  eventbus-addresses tho. 

When you you dont use the service discovery, you could do the same, just use different address. But you need to know the address used by your verticles.
