Materialized views based on access rights

Abstract:

The subject technology defines a materialized view over a source table that is associated with a first account of a database. The subject technology defines cross-account access rights to the materialized view for a second account. The subject technology modifies the source table for the materialized view. The subject technology identifies that the materialized view is stale with respect to the source table by merging the materialized view and the source table. The subject technology causes the materialized view to be refreshed with respect to the source table.
