With the the release of 1.2 and the introduction of the new SQL-like query language it was mentioned that this opened to door to being able to swap out MongoDB for an alternative database engine (e.g. MySQL, PostgreSQL?).
This is something that is still planned or on the horizon? We don’t run MongoDB in our stack at all but we have to for GenieACS, and we’l like to remove that overhead in the future if at all possible.
