  "summary": "AWS has introduced foreign key constraints in Aurora DSQL, a serverless, distributed PostgreSQL-compatible SQL database. This addition addresses a long-standing gap that users had called out as an adoption blocker. Aurora DSQL enforces referential integrity through snapshot verification during transactions and conflict detection at commit time, allowing concurrent operations without locking tables. Applications can implement retry logic for transaction failures due to concurrent conflicts. AWS has received positive feedback on the new feature, though some users question its impact on performance due to the additional reads required for referential integrity.",
