Client filtered GeoEvent Server output

Hello!

I was sent to this forum from the Qt runtime forum So runtime does not have GeoEvent Server functionality baked into its API. I was however able to manually open up a web socket, subscribe to a GeoEvent Server, and consume its output manually in our Qt/runtime based application. My question is, when hitting that subscription URL is there a way to filter the output that gets streamed over the open web socket? Just thinking that would be a more efficient way to minimized network traffic, especially for a mobile device, rather than streaming all the GeoEvent server's data and doing the filtering client side.

Thanks!

Jeremy

Hi Jeremy Roberts‌,

you are absolutely right, that would be nice to do this on server side. As far as I know there is currently no way to do this to filter it on the server using Stream Layer or the out of the box websocket output. Sure you could create a few outputs and filter which data will be send via which output, but an output will always send all data it receives regardless of the client.
