We're a hosting provider with our own hardware and we have cutsomers asking to operate SigNoz on our infrastructure. That rises two questions : • What are the actual limits of the community self-hosted SigNoz version ? What is the max number of whatever resource is limited ? I see from the github repo that the "query-service" module is not open source but what exactly is the query-service module ? Reading through the website did not make things clear for me • What is the process to become an infrastructure provider for SigNoz ? We are interested in hosting products like SigNoz
