Racing for commits on Delta Lake tables using Starburst
Blog post from Starburst
Delta Lake, an open-source table format, plays a pivotal role in data analytics and engineering by leveraging Snapshot Isolation for read operations on different dataset versions, enabling functionalities like Time Travel. However, maintaining ACID guarantees during concurrent write operations presents challenges, which can be mitigated using Starburst's integration. Delta Lake's architecture, involving Parquet file data storage and a transaction log, supports efficient data handling and ensures data integrity by recording every transaction as metadata. Conditional and concurrent writes in Delta Lake allow for multiple users to work on a dataset simultaneously without compromising data integrity, a feature previously unsupported by Amazon S3 until its recent update. Starburst enhances this capability by supporting conditional writes on Amazon S3, allowing for reconciliation during concurrent writes to prevent data corruption. This functionality facilitates independent team operations on a single dataset, ensuring agile data management. These improvements in Delta Lake's concurrent write capabilities, supported by Starburst, optimize data processing across various workloads and enhance the overall data architecture's reliability and performance.
