Here is an example of `CatalogProvider` from IOx: https://github.com/influxdata/influxdb_iox/blob/be662ec7318e83fc54f8a6e942a3dc8abbc84bc4/db/src/access.rs#L316 Here is an example of a `SchemaProvider` (from IOx) that is used to provide some virtual system tables: https://github.com/influxdata/influxdb_iox/blob/d9f331ba2ae3885497c480a5e5b6940698ae0f63/db/src/system_tables.rs#L106-L134 The main use case is "we have some other structure that already keeps track of schemas / tables and we want to expose that information to DataFusion without having DtaFusion manage it" -- This is an automated message from the Apache Git Service.
