Pin down SQL Alchemy to <2 #1289

Closed rafaelweingartner closed 1 year ago

rafaelweingartner commented 1 year ago

Version 2 of SQL Alchemy has been released, and it brings considerable changes to it [1]. The one that is affecting us right away is the philosophy of always using a transaction. That means, for every connection open with the database (DB), there is automatically a transaction opened. This, in turn, breaks the current code structure that we have, where we try to open a transaction every time we get a connection to write or read in the DB. The break happens because the code is trying to open a transaction inside an already existing one (the transaction opened by SQL Alchemy itself).

This whole situation only happens with SQL Alchemy >=2. Therefore, for now, the solution is to pin down its (SQL Alchemy) version until we have a final solution, which is going to have a considerable impact in the transaction management that we currently have.

P.S. This one should be merged only after this other: https://github.com/gnocchixyz/gnocchi/pull/1288
