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 `data_stores` are classes that talk directly to a single
|
|
database and have associated schemas, background updates, etc. On top of those
|
|
there are (or will be) classes that provide high level interfaces that combine
|
|
calls to multiple `data_stores`.
|
|
|
|
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`.
