Hi, I'm working with a client that wants to build a streaming analytic chart but with the option to switch mode to snap to historical data. Typically we can use a GW to stitch RDB and HDB data together but this use case is slightly different in that we need to stitch streaming data with HDB data.
We have a working POC using a rather unconventional approach, we utilize a lot of the QR APIs to make the HDB query a deferred request so that it doesn't block the streaming process. I'd like to reach out to see if there are other possible solutions and raise the challenges we're currently facing.
Current Solution (kdb 3.5, Dashboards V4.3.1)
Looking forward to see how we handle this with other projects/clients.
