I'm not the guy in change of this, so what I can tell you is only based 
on what I've heard over these months: replication is not working fine 
with PostgreSQL and packaging of the relational database can be a huge 
issue with MySQL.

also, the use of blob storage outside the relational database 
complicates the replication process.

the idea of creating image scales on the fly probably solved one problem 
(disk space) but created a new one (POSKeyError: 'No blob file') on 
these deployments.

best regards
