Stream layer compression

Good Day

Would it be possible to use compression with the Stream Layer web socket? If so, how do you enable it, if not, why?

Thanks

Hi @AndrewMurdoch1 The ArcGIS GeoEvent Server and ArcGIS Velocity products do not currently offer compression on stream layers. We will explore parameterizing this for a future release. Is there currently a rate or load that you are unable to keep up with that pushed you towards investigating compression with this Stream layer web socket?

Thanks! When the socket response gets heavy, 250 MB+ we have a fair amount of load, which takes a while to load, We have taken steps to chunk the data, which helps, but compression would be very welcome 🙂

Thanks

Good Morning

Is there an updated timeline for this? Getting into ArcGIS JS (if not there), would be very helpful.

Thanks

Hi @AndrewMurdoch1 , This is a functionality we are still considering for future releases and is represented in our backlog, but it is not on the near-term roadmap.
