Divyansh S. developed support for BigQuery INTERVAL data types within the BigQuerySqlDialect module of the datametica/calcite repository, focusing on enabling INTERVAL MINUTE_SECOND and INTERVAL YEAR_MONTH compatibility. Working primarily in Java and leveraging SQL dialect implementation expertise, Divyansh introduced these enhancements through two targeted commits, ensuring robust test coverage and integration with existing query translation workflows. This work addressed cross-dialect compatibility issues, reducing query failures and streamlining onboarding for BigQuery users. Although no major bugs were fixed during this period, the feature was delivered with attention to quality and reliability, improving the overall stability of interval-based queries.
