Essentially, one database to rule them all?

It is very much the opposite. With this pattern, you're going to have lots of copies of your data in different transformations in potentially many different data stores. The idea is that you take the stream of changes from something like Postgres and use that stream to populate caches, indexes, denormalizations/representations, counts, etc.

One append-only data structure to rule all them databases.
