Temporal Data

Temporal database patterns for system-time versioned tables. Use when working with tables that have system_from/system_to columns, temporal queries, non-destructive updates, merge/sync logic, rollback, or schema migrations involving temporal data.

Efficient data loading patterns using system_from/system_to for cache validation. Use when implementing incremental sync, conditional fetches, polling for changes, ETags, high watermarks, or avoiding redundant data transfer in systems with temporal tables.
