Apache ignite

how can i configure traccar to work with apche ignite or any other in-memory database?

Curious about the reason. Ignite is not meant for the kind of data traccar produce and store

Since ignite is an in-memory database so we want to integrate it with traccar instead of mysql or any other dbms.(Help needed)

So, we have these teltonika fmb IOT devices which will be constantly sending live data to work with. Thought we might need an in-memory database (such as apache ignite) to improve the performance with the huge amount of data. what's your take on this?

It seems that you need to build your own tracking server from scratch.

Traccar already has in-memory cache for everything, including live data, so it doesn't really make sense to use in-memory database.
