pub(crate) static DATABASE_FAKE_NAME: &strExpand description
The name of the fake database used to fit references into the 3-layer catalog
model of the SourceReferenceResolver for source types whose
ReferenceMetadata::external_reference stores no database component
(MySQL and Kafka). Because those references are never fully qualified with a
database, the resolver’s database name is never matched against and this
placeholder is never stored in the catalog.
Note: this is not usable for every non-Postgres source. SQL Server and load
generators do store a database in their external reference (the real upstream
database and the synthetic mz_load_generators, respectively), so their
resolvers must be built with that same database for the stored reference to
resolve. See the resolver construction in SourceReferenceClient.
