Can I get your use case? What is the data you have to index? If it's logs, indeed, Meilisearch will not be the best fit. I would recommend https://quickwit.io. If it's structured or unstructured data, even if 10TB seems huge for our use cases, I would love to put you in contact with my engineering team. We would find a way to manage it.
I'm curious also about your use case (disclaimer, I'm one of the cofounder of Quickwit). Do you want simple search with a basic UI? Or some dashboarding with grafana for example?
