Well, the relational database is suitable for the quickly evolving part
of their business, and there will always be a quickly evolving part of
any business, so yes - inevitability is the perfect description.
Now that their business has stabilised and they know what a larger part
of it is supposed to do and what the performance goals they need to
reach are, they can begin to crate a more specialised datastructure
optimised for their (now known) use case.
Question is - can they create such a specialised datastructure such that
it _can_ evolve, for example, in the case where they wanted to handle
not just 140 byte tweets, but also photos and video (twotos, and twideos)?
