Feature: Websockets for Data-Refresh

[ansibleguy]

Scope

Backend (API)

Description

Currently we fetch all the data-entries of the current view every refresh-interval (1 sec).
We then check if the data has changed using JS and update the table-rows in that case.

It would be nicer to only fetch the changed datasets. That way we could save on transferred data.
This would mean we will have to pre-filter the data on the backend and implement web-sockets

This is not really an issue for now - but I dislike the current handling as it is somewhat unclean.
