Worked on the googleapis/java-bigquerystorage repository to enhance error handling in the streaming write path, focusing on improving reliability and the developer experience. Implemented user-facing mitigation guidance within the StreamWriterClosedException, enabling clients to respond to transient UnavailableExceptions by retrying with backoff. Updated error messages to align with public documentation, reducing confusion and support overhead while streamlining customer workflows. The work leveraged Java and emphasized robust exception management and error handling practices. By providing actionable guidance directly in exception messages, the changes aimed to make error recovery more intuitive for users and to support smoother integration with the BigQuery Storage API.
