aps-doc-hist-union

Hist-union documentation generation extracts union logic, merge strategies, and backfill processes from your .dig, .sql, and .yml configuration files. It produces production-ready documentation with real table names, actual SQL examples, file paths, and line numbers for incremental and full-load patterns.

The Skill applies schema validation and consistency checks as part of hist-union documentation, ensuring merge rules are correctly implemented across multiple databases. It captures watermark management and backfill considerations in the generated documentation.

Yes. Hist-union documentation handles incremental and full-load patterns, watermark tracking, and backfill processes. It documents the merge strategies and SQL union logic required for backfill operations across your database workflows.

The Skill parses .dig, .sql, and .yml files to derive working SQL examples and union logic directly from your codebase. It documents the actual SQL transformations with real table names and file references for transparency.

Documenting merge strategies ensures reproducibility, reduces errors during incremental updates, and clarifies watermark boundaries and backfill logic. Production-ready documentation with working examples prevents inconsistencies across multiple databases.
