Abstract: Methods and systems for coordinating migration for a database of a service are described herein. Multiple releases of the service may be simultaneously implemented, and these multiple releases may access a shared database. As new releases of the service are activated, the database may be incrementally migrated to a new data schema version. The new data schema version may be compatible with each release of the service that is in use. After a migration has begun, instances of the service may be instructed to perform database operations using methods compatible with the new data schema version. Continuation tokens may be returned during the migration, which indicate portions of the shared database that have not yet been migrated. If an error occurs during the migration, the continuation tokens may be discarded, and the migration may be restarted.

Abstract: Methods and systems for sharing data among multiple services are described herein. Multiple services may access data from a shared data source. The services may subscribe to data sharing events. A data sharing service may iterate through the shared data source and transmit data retrieved from the shared data source in data sharing events. When the data sharing service reaches the end of the shared data source, the data sharing service may begin iterating through the shared data source again from the beginning. The data sharing events may be transmitted at a predetermined frequency. The services may subscribe to or unsubscribe from the data sharing events.
