Welcome to the community! š
1. Given the similarity of the Orion and Core client APIs, upgrading should require minimal effort on users' behalf. But we will also provide upgrade guides and tools to make Orion adoption as easy as possible for Prefect 1.0 users.
2. We expect to have a beta release close to the end of Q1 or early Q2 but please consider it just a rough ETA. You can follow
#announcements channel in the next months to stay up to date with all Orion releases. You can also hit the š icon on
this Discourse tag to get email notifications about all future releases.
3. We support SQLite and Postgres, but I doubt MySQL will be supported as it has different syntax and is less performant than Postgres. For more details on that, check out
this documentation page.
