Abstract: A materialized view created by a materialized view management platform may be replicated across many different target systems. The materialized view management platform allows users to specify different target systems. To create the materialized view in the different target systems, the materialized view management platform can translate the materialized view into different formats in order to store the materialized view in the different formats. Updates to the different instances of the materialized view are then made to keep the different materialized view formats in the different target systems up-to-date.

Abstract: Materialized views may be generated at a managed materialized view platform that accepts data streams as a source. When updating a materialized view with a data stream as a source, a stored portion of the stream is used to maintain a history of changes to be made. When a join operation needs to utilize the data stream source to determine an update to the materialized view, the data stream is preserved to complete the join and update the materialized view.

Abstract: Managed materialized views may be generated from across heterogeneous data sources. A request to create a materialized view may be received and performed by a materialized view management platform, which may obtain and generate the materialized view from different data sources and store the materialized view in a target system. Changes to the data sources may be obtained at the materialized view management platform and updates to the materialized view may be determined. The materialized view in the target system may be updated.
