A consumer database of a service provider network may perform writes to a producer database. To do so, the consumer database obtains metadata and a transaction context from the producer database and uses that information to perform a write from the consumer database to the producer database. A consumer database may access (read and/or write) a producer database that uses a different topology to manage data. To do so, the consumer database obtains topology metadata from the producer database and uses the topology metadata to perform a query (read or write) from the consumer database to the producer database. A consumer database may access a producer database based on a mapping of local user IDs to consumer databases at the producer database. The access may be granted to the consumer database based on permissions assigned to the local user IDs.
