My hope is that managed data layers become more available and the problem space of "custom data structures and indexes" can be decoupled from the even harder parts of writing a database. Projects like pgrx (postgres extensions in rust) are starting to make it much more approachable to do so. A little lower level: build on FoundationDB. (Projects like mvsqlite are super interesting here). In both cases, we don't yet have fully managed providers. RDS seems to be flirting with opening up the extension ecosystem with trusted languages. I haven't seen any managed foundationdb offerings though.
