Does drawio support JSON data format and incremental data storage

[PragueJoker]

Hi，thanks for this excellent open source project.

I have some questions to answer

First,Can drawio support JSON data format?【I want to transform drawio to support real-time collaboration. I investigated some OE algorithms based on JSON format data】

Second,Can drawo support incremental data storage?【I have stored the data of drawio in mysql, but every time the server receives the full amount of data, the data is very large, even if I only move the elements on one page】

If the above two problems are not supported at present, I hope to get a direction to solve the problem.
