Worked on the ollionorg/DataflowTemplates-fork repository to deliver support for Spanner Import/Export INTERLEAVE IN table definitions, enabling more accurate migrations and integration with Avro workflows. The implementation involved generating DDL statements, mapping interleave types from information_schema, and validating schema relationships, including ON DELETE actions for parent-child tables. Java and SQL were used to update integration tests and improve code readability, focusing on maintainability and data fidelity. This work addressed the need for reliable schema migration by ensuring correct handling of interleaved tables, enhancing the overall robustness of backend data engineering processes involving Spanner and Avro data formats.
