RocksDB Variants that Automatically Offloads Old Data to A Remote Site

[yasurok]

First off, let me apologize for hardly knowing anything about Tuwunel. I've just started trying to find the right Matrix server. Please forgive my ignorance.

I need to run this Matrix server on a VPS -- specifically, an ARM compute engine on Oracle Cloud's free tier (2 CPU, RAM 12GB, storage 200GB). I do not want to exceed these limits and pay for the extra. I do not expect the Tuwunel server to be used super frequently by super many people, but eventually it will hit the storage limit. I have no idea when it will be, but I am trying to have a way to deal with this situation before it actually happens.

I can run a server on my NAS and expose it to WAN. I plan on running an S3 compatible storage service and have Tuwunel store its media files there. So I believe that part can be taken care of this way. Now the question is how to deal with RocksDB.

Gemini says there are a few systems that are RocksDB compatible which automatically offloads old data to a remote site. Are you familiar with these systems? Is it difficult for a novice user to use one of these systems in place of the RocksDB proper with Tuwunel?

Please advise.

Thank you!
