The storage layer is split up into multiple parts to allow Synapse to run
against different configurations of databases (e.g. single or multiple
databases). The `Database` class represents a single physical database. The
`data_stores` are classes that talk directly to a `Database` instance and have
associated schemas, background updates, etc. On top of those there are classes
that provide high level interfaces that combine calls to multiple `data_stores`.

database. The `databases` are classes that talk directly to a `DatabasePool`
instance and have associated schemas, background updates, etc. On top of those
there are classes that provide high level interfaces that combine calls to
multiple `databases`.
There are also schemas that get applied to every database, regardless of the
data stores associated with them (e.g. the schema version tables), which are
stored in `synapse.storage.schema`.
