Generating Referentially Consistent Synthetic Test Data for PostgreSQL in .NET Application Modernization

Satyajit Gokhale, Aiswaryaa Venugopalan, Ruchi Agarwal, Nits Jeganathan, Khurram Khawaja, Vijay Mandadi, and Luke Huan contributed to this article. AWS Transform offers a .NET application modernization service that allows enterprise customers to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL Compatible Edition. This migration reduces licensing costs and enhances scalability while utilizing an open-source ecosystem. Schema conversion tools can assist in translating DDL to PostgreSQL-compatible definitions, but correctness must be verified by teams to ensure performance under real-world workloads. Traditional testing methods, such as using production data or manual checks, are not scalable and raise privacy concerns. Therefore, there is a need for realistic synthetic data generated at scale that adheres to the migrated schema's constraints. AWS Transform for SQL Server modernization employs an AI agent to generate constraint-respecting synthetic data at scale during the migration workflow. This process involves loading the PostgreSQL schema into a live database, constructing a dependency graph for data generation, and distributing tasks across multiple sub-agents. The agent validates each generated INSERT against the live database, ensuring compliance with constraints and providing error diagnostics for any violations. The synthetic data generation workflow consists of four stages: schema analysis, establishing generation order, distributing tasks across sub-agents, and validation with error recovery. The agent extracts metadata from the PostgreSQL schema, determines a valid table generation sequence, parallelizes data generation while maintaining referential integrity, and generates and validates data row-by-row against the live database. Each successful insertion enriches the context for subsequent generations, while errors are handled through structured diagnostics and iterative regeneration. The process ensures referential integrity and preserves the generation state, allowing for recovery from interruptions without data loss.

EDB Says Postgres AI Tops Enterprise AI Data Platform Benchmarks

EnterpriseDB (EDB) has released benchmark results for its EDB Postgres AI (EDB PG AI), showing superior performance compared to various AI data platforms, including vector databases and managed Postgres platforms. The independent testing by McKnight Consulting Group indicated that EDB PG AI outperformed competitors in all evaluated metrics, including query speed, accuracy, and cost efficiency. Key findings include: - EDB PG AI achieved a median query latency of 50 milliseconds at 50 million vectors, making it the fastest platform tested, 80 times faster than Databricks and 21 times faster than MongoDB Atlas. - It demonstrated the highest accuracy for core vector search with a recall rate of 0.911, outperforming MongoDB by 26% and Databricks by 17%. - In a concurrent agent loop test, EDB PG AI completed tasks in 27 milliseconds, significantly faster than MongoDB Atlas (699 milliseconds) and Databricks (5.1 seconds). - EDB PG AI provided 76 times better price performance than Databricks and 34 times better than MongoDB. - The platform integrates vectors, structured data, and analytics within a single operational database, enhancing efficiency and reducing the risk of data inconsistency. The benchmark study assessed the performance of EDB PG AI against Amazon Aurora PostgreSQL, Databricks, Crunchy Bridge, MongoDB Atlas, and open source PostgreSQL, all standardized on equivalent enterprise hardware.

Old School RuneScape players are getting their boats stuck Suez Canal-style thanks to a narrow river in its new island: ‘Helmp mee’

Old School RuneScape has introduced Wyrmscraig, a player-designed island featuring a new quest, a repeatable boss, and a new sword. The Wyrmscraig Cavern, accessed via the sailing skill, has a narrow river entrance that can lead players to get stuck between rocky shores. This issue has prompted discussions on the game's subreddit, with players sharing their experiences. An NPC named Cormac warns players about the navigation challenges, advising them to use smaller boats to avoid getting stuck. The addition of the sailing skill has enhanced gameplay and fostered humorous interactions within the community.

Australia’s online watchdog is taking messaging app Telegram to court over ‘pro-terrorist’ posts

Australia’s eSafety Commissioner, Julie Inman Grant, has filed a lawsuit against the encrypted messaging app Telegram for allegedly failing to detect and remove pro-terrorist and extremist content. This legal action follows a year-long investigation and is the first enforcement of online codes regarding unlawful material established a year ago. The lawsuit details multiple violations of the Online Safety Act 2021, including the failure to remove posts related to the Christchurch mosque attack and the Buffalo mass shooting, despite user reports. Telegram has claimed to have blocked over 150,000 terrorist-related communities and removed over 200 million pieces of terrorist content. If the lawsuit is successful, it could lead to penalties up to A.6 million and potentially a ban on the app in Australia.

How to remap the Windows 11 Copilot key and restore your missing Right Ctrl button

The Copilot key, introduced by Microsoft on Windows laptops over two years ago, is located to the right of the spacebar and provides access to Microsoft's Copilot AI. This key has been adopted by various manufacturers, including Lenovo, Dell, and HP, and is now found on many laptops even if they are not labeled as Copilot+ models. The key can replace the Right Ctrl key or the Context menu key, which may disrupt users' workflows. Microsoft plans to release an update for Windows 11 that will allow users to remap the Copilot key to function as the Right Ctrl key or the Context menu key. Two methods to remap the Copilot key include using Windows settings and Microsoft's PowerToys Keyboard Manager. Users can test the remapped functionality and revert changes if needed.
