Websocket Disconnected Because DataFrame/Message Too Large with Perspective

Ignition

#1

Hello,

I am receiving this error in the logs -

Websocket connection closed unexpectedly. 
code=1009, 
reason=Resulting message size [2102265] is too large for configured max of [2097152], codeMeaning=Message Too Big, 
codeDescription=The endpoint is terminating the connection because a data frame was received that is too large.

I am working with some large dictionary structures, and passing them as parameters across different embedded views. I'm optimizing my strcuts to decrease the size of data. I have a couple of questions.

Would I be better to use a dataset or a JSON encoded dictionary to pass parameters instead of a Perspective Object? Maybe the best question here is what is the most data-friendly structure to use (lists vs datasets vs objects vs JSON-encoded objects/lists)

Lastly, where can I increase the max message size, and is this a bad idea to do so?

Thanks!!

Datasets are better, generally, because they have an optimization throughout of not needing to render (and listen for changes on) all inner members.

Making properties private also helps a lot, though I don't know if you can do that for view parameters. I would consider different approaches; can you 'batch process' this data entirely on the gateway so you don't have to send so much between views at all?
