Abstract
A system performs write protection of data that being copied. The write protection protects the data from being corrupted by applications. The system allows writes that are part of the data transfer from the source database. The system uses triggers to implement write protection. The system stores a list of tenants that are write protected in a metadata table. The system implements a statement level trigger that caches the metadata table in memory. If the cache is determined to be older than the limit specified by the TTL, the system reloads the cache. The statement may perform multiple row level operations. A row level operation implements a row level trigger that checks the in-memory data structure to determine whether the tenant is write protected. If the tenant is determined to be write protected, the system rolls back the row level operation.
