>> when disk space was expensive and The biggest caveat for oracle and other proprietary solutions is the /dynamic/ licensing/pricing models having an effect on architecture based on disk, cpu and other paremeters. With OSS solutions, postgres/mariadb etc I have the flexibility of deploying as many nodes, disks, cpu, machines as I want without thinking of how will effect the price, and without worrying of a sales organization tracking my use. That's why I don't worry about clustering, partitioning, linking and many other features lacking. If I'm going to plan for 100M to 2B monthly active users for a growing organization Oracle/Ms SQL aren't an option at all. For small scale of up to 10K users, they seem to have a use case for "legacy" organizations.
