## Summary of Changes Hello @claudevdm, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the BigQuery Storage Write API integration by introducing comprehensive support for nanosecond-precision timestamps. It enables users to accurately store and retrieve time-series data with sub-microsecond granularity when using both Avro GenericRecords and Beam Rows, aligning with BigQuery's `TIMESTAMP` type capabilities. The changes involve updating schema mapping logic and data conversion mechanisms to correctly handle nanosecond values, ensuring data integrity and precision. ### Highlights * **Nanosecond Timestamp Support**: Enabled writing nanosecond-precision timestamps to BigQuery via the Storage Write API. * **Avro GenericRecord Handling**: Implemented detection of `timestamp-nanos` logical type, mapping it to BigQuery `TIMESTAMP` with precision 12, and converting `Long` (nanoseconds since epoch) to `TimestampPicos` proto messages. * **Beam Row Handling**: Added support for `Timestamp.NANOS` logical type, mapping it to BigQuery `TIMESTAMP` with precision 12, and converting `java.time.Instant` to `TimestampPicos` proto messages. * **Schema Definition Updates**: Ensured that BigQuery schema generation correctly sets `timestampPrecision = 12` for nanosecond timestamp fields in both Avro and Beam schemas. * **Comprehensive Testing**: Introduced new unit and integration tests to validate the correct serialization, deserialization, and end-to-end writing/reading of nanosecond timestamps for both Avro GenericRecords and Beam Rows. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback.
