Yes. Aurora has replaced the PostgreSQL storage engine, but the MVCC part is largely the same. The issues with
vacuumingare largely overstated, though, and alternative system for concurrency control have their own issues.

That's probably best addressed to a MySQL-oriented list, or directly to Amazon.
It should be noted that Aurora is a commercial product, and much of it is closed-source. User communities will have
somewhatlimited ability to offer advice about it.
