I have a kubernetes cluster with a set of pods and two loadbalancer services. When a incoming requests comes I want to route the request to correct service by checking the query param and making some additional processing on the query param. I know we can route it according to the value of param1 but is it possible to perform additional operations on param and then route it accordingly.
I am planning on using https://docs.solo.io/gloo-edge/latest/.
eg:
/foo?parm1=123
Is possible to get the value 123 and run a script( query a db with that value or convert to binary etc ) to process the value 123 and get a new value and according to it route to a specific service.
You can create a WASM filter with your own custom logic. To get you started check how to install and use the wasme cli
And then how to use WASM Filters in Gloo Edge
That said, because you can do this, it doesn't mean that you should. I would discourage adding such type of logic in the API Management (which should merely handle API Management)
