Forking http/https requests at data power level to send them to a different backend
We are using data power web service proxy/multi protocol gateway. As part backend migration, we are building a parallel data pipeline. we thought achieve this by forking all the requests at data power and send them to a different destination. Does data power supports sending parallel requests to different destination apart from original backend end? Please help me.
Yes, DataPower does support this. You can configure multiple destinations in the results action of a request rule in your processing policy to achieve this.
You will need to enable Multi-Way Results Mode and configure the relevant fields. For the destination, specify a nodeset following the results element:
Hope this helps - let me know if you have any other questions!
Thanks for the quick update. I explained my requirement and fitting your solution to my usecase.
Check the diagram for my use case. I want my two backends to have the same data (Backend1 and Backend2 have same endpoints.). I gone through "Results actions". I am unable to fit my use-case. I will provide the backend1 while create data power proxy (webservice/mpgw). Using results actions, I will provide the backend2 base url in target. and then method type and endpoint (suffix) should be inherited from proxy/backend1. Each request to the proxy endpoint, send the requests to backend1 and backend2.
client ---------> DP proxy -------------> backend1 (api) -----------> db1 | fork | -------------------------> backend2 (api)-----------> db2
Please check the below image for my requirement.
