AWS embeds DuckDB in its PostgreSQL DBMS to speed queries of live and historical data

Amazon Web Services Inc. has enhanced its Aurora PostgreSQL database management system to allow users to query the Apache Iceberg data lake directly. This feature integrates the DuckDB analytical engine, enabling seamless access to live transactions and historical records without data duplication or complex ETL processes. Customers can use existing PostgreSQL applications to query data in Amazon S3, including S3 Tables. The integration aims to reduce the engineering workload associated with data pipelines and supports real-time applications. DuckDB processes analytical scans within Aurora, eliminating extra network hops and allowing single queries to access both live and archived data. The feature supports external catalogs compliant with the Iceberg REST Catalog specification and can create foreign tables referencing data across multiple catalogs. Aurora optimizes query performance by filtering records and caching frequently accessed data. Customers can combine recent transactions in Aurora with historical data from S3 without manual schema definitions. For low-latency workloads, selected data can be copied into native Aurora tables using standard SQL. This capability requires the aurora_analytics extension and an AWS IAM role for S3 and Glue access, and is compatible with Aurora PostgreSQL versions 17.11 and 18.6. The feature is available across all AWS regions at no additional charge, with costs incurred only for Aurora computing resources and S3 requests.

AWS Embeds DuckDB in Aurora PostgreSQL, Enabling Direct Data Lake Queries Without ETL

Amazon Web Services (AWS) has integrated the open-source analytics engine DuckDB into its Amazon Aurora PostgreSQL database, allowing users to query Apache Iceberg tables and Parquet files directly from data lakes without traditional ETL processes. This feature, announced on September 30, 2026, enables seamless access to both operational and historical data in a single SQL statement. Users can enable the aurora_analytics extension, assign an IAM role for S3 and AWS Glue access, and create external tables using standard PostgreSQL syntax. The integration supports Iceberg tables managed by AWS Glue Data Catalog, Iceberg REST Catalog-compatible external catalogs, Parquet files on S3, and S3 Tables. Performance optimizations include predicate pushdown and column pruning on the data lake side, with caching for frequently accessed data. This feature is available for Aurora PostgreSQL versions 17.11 and later, and 18.6 and later, across all commercial regions and AWS GovCloud (US), with no additional charges beyond Aurora compute and S3 request fees. In a separate development, AWS has a significant contract with AI company Anthropic, anticipating billion in cloud-related contractual obligations over several years, with approximately billion projected to be paid to Amazon from a 10-year agreement announced in April 2026. Anthropic's revenue has shown impressive growth, with first-quarter 2026 revenue reaching 0 million and second-quarter revenue at .8 billion. However, risks are present, as a significant portion of Anthropic's revenue comes from a few customers, and many larger clients lack long-term contracts. Amazon has invested .8 billion in Anthropic, with its stake valued at approximately billion as of June 2026.

Why Alternative App Stores Are Gaining Popularity Among Android Power Users

An alternative app store allows users to access apps and games not available on official platforms like the Google Play Store, including older versions, regional apps, and open-source options. Types of alternative app stores include third-party Android stores, open-source platforms, modified APK stores, regional stores, free app stores, and game-focused stores. Users explore these stores for a broader selection of apps, including those restricted by geography. Alternative app stores can provide apps that Google Play does not, such as regional apps and modified applications. When choosing an alternative app store, users should consider the platform’s reputation, app descriptions, update frequency, security measures, and source verification. Alternative app stores differ from Google Play by offering more flexibility and access to unique content, though security and developer support may vary. Modified apps are altered versions that may offer enhanced features. Alternative app stores are important for overcoming regional barriers and providing ad-free experiences. They host a variety of apps, including multiple versions of a single application, and typically feature user-friendly search functionalities. Comprehensive app information is often available, including version data and permissions. Some stores focus on open-source and independent apps. The legality of using alternative app stores depends on licensing and local laws, and they often feature apps not found on Google Play. Many alternative stores provide multiple app versions, and only reliable ones may offer faster updates.

Why Antivirus Flags Game Tools and How to Verify Downloads Safely

In gaming, tools such as utilities, beta applications, and modding tools are often distributed as APK, IPA, or desktop files, and it is essential to investigate their origin, version, and any security warnings before installation. Antivirus software flags potential threats based on known malicious signatures, behavior patterns, and reputation data. Tools that modify game clients may receive heightened scrutiny, and classifications like “HackTool” or “Riskware” do not definitively indicate a file's functionality. Identical game utilities can exist on various platforms, and a familiar website does not guarantee authenticity. It is crucial to verify the publisher, update date, version, and installation method of a file. The SHA-256 hash verifies file integrity but does not ensure safety from malware. Calculating a file hash can be done using specific commands in Windows, macOS, or Linux. Multi-engine scanning platforms like VirusTotal provide insights, but a lack of detections does not guarantee safety. Even if a file matches its reference hash and raises no alerts, it may still violate online game terms. A pre-installation checklist includes confirming the publisher, checking file types, comparing SHA-256 hashes, reviewing security findings, keeping antivirus protection enabled, and consulting platform rules. A cautious approach integrates source verification, file integrity checks, security assessments, and compliance with platform regulations.

DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.
