51.06% of diff hit (target 95.00%)

the code coverage for new code is quite low, can you add tests for the error edge cases?

[yurishkuro]

@akstron I refactored the changes a bit to move session and schema creation into the actual storage implementation and leave the config package to only deal with configuration, not with creating live sessions.

🎉 🎉 🎉 great job @akstron
