Query cache usage question

I am using React with convex and the query cache from helpers.

If I add useQuery(api.todos.listTodos) in multiple components in the same page, will this generate one query for each mount (as in multiple queries to this function in the same page) or is it using a global cache and call the query function just once?

I am coming from TenStack Query that reuses the active query across components and i cn;t find specific about this behaviour in useQuery from convex.


Thanks

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
