Hello Sentry Team, thank you for making a great product. I am learning a lot by breaking the code one by one. While analyzing the infrastructure in my own way, I have a question, so I contacted you. What happens to the correct operation process when the accumulated events are upgraded? In the error event that was previously contained in 9.1.2 postgres, it is confirmed that most of the data in 20.11.0 go to the clickhouse through snuba after migration through install.sh. Is it correct? Also, I thought that some of the existing error events are moved to postgres and most of them to clickhouse through “docker-compose run --rm web upgrade” during migration in install.sh. Is that correct?
Finally, it seems that the clickhouse contains information related to sessions other than the error event. So, I wonder if you plan to actively use clickhouse for data that does not need to be included in relational db and needs to be processed quickly in the future.
I’m really, really curious about how events move when versioning up, and how events accumulate and consume in the 20.11.0 architecture in general. There are so many things to learn about architecture. Please explain in detail!
