The SingleStore Storage Service is a critical component of several key features, including Notebooks and Stage, built on top of cloud blob storage with added features tailored to specific use cases. The authors recently migrated away from MinIO, which they used for mocking Amazon S3 in development environments, due to limitations and discrepancies that impacted testing and development. These challenges included the need to maintain separate codebases for local development and production environments, reduced test coverage, and inconsistencies between file naming conventions. After investigating alternatives, they switched to LocalStack, which provides a more comprehensive emulation of the AWS environment, allowing them to create realistic testing scenarios and streamline their development process. The migration has improved stability and reliability, reduced complexity, and removed approximately 2,000 lines of code, enabling the team to focus on future projects with enhanced capabilities.
