Gold Lapel launches PostgreSQL proxy to tune queries

Gold Lapel has introduced a PostgreSQL proxy that enhances database query performance by acting as an intermediary between applications and PostgreSQL databases. The proxy monitors live queries, identifies issues, and implements optimizations such as creating materialised views, introducing various index types, and rewriting queries. It supports over ten optimization strategies, seven programming languages, four frameworks, and three ORMs, and is available for Linux, macOS, Windows, and Docker. The software includes features like prepared statement caching, in-memory result caching, connection pooling, automatic read replica routing, and security measures including TLS. An observability layer provides a live web dashboard and audit timeline. The pricing model is USD 9 per month per instance, with a site license available for unlimited instances. Gold Lapel has also released a 19-chapter technical book on PostgreSQL performance optimization. The company was founded by Stephen Gibson and is based in San Francisco.

Netflix Automates RDS PostgreSQL to Aurora PostgreSQL Migration Across 400 Production Clusters

Netflix has developed an internal automation platform to migrate Amazon RDS for PostgreSQL databases to Amazon Aurora PostgreSQL, reducing operational risks and downtime for nearly 400 production clusters. The platform allows service teams to perform migrations through a self-service workflow while ensuring processes like replication validation and rollback safeguards are maintained. Database access is managed through a platform-managed layer using Envoy, which standardizes mutual TLS and abstracts database endpoints, enhancing security and efficiency. The migration process starts with creating an Aurora PostgreSQL cluster as a read replica of the source RDS instance, initialized from a storage snapshot and continuously replaying write-ahead log (WAL) records. Validation checks are performed to ensure the replica can handle peak write throughput before cutover. For change data capture workloads, the system coordinates the state of replication slots and pauses CDC consumers to prevent excessive WAL retention. The Enablement Applications team at Netflix successfully migrated databases for device certification and partner billing workflows, addressing issues like elevated replication lag due to inactive logical replication slots. As replication lag decreases, the system enters a controlled quiescence phase, adjusts security rules, and reboots the source RDS instance. Once all transactions are processed and the Aurora replica is ready, it is promoted to a writable cluster, and traffic is rerouted. Rollback capabilities are prioritized, allowing redirection back to the original RDS instance if validation checks fail or anomalies are detected post-promotion. This setup enables seamless restoration without redeployment, and CDC consumers can resume from recorded slot positions if needed.

The best Minecraft ideas for Spring Break in 2026

Minecraft players can enhance their gameplay during spring with various Easter-themed mods and projects. Notable mods include the Painted Egg mod for crafting and dyeing Easter eggs, the Easter’s Delight mod which adds a bunny villager and Easter-themed food, and the Hendrix’s Better Spring to Life mod that introduces new creatures and elements. Players can engage in creative projects like creating Easter egg trails, designing bunny burrows, or building giant replicas of the Easter Bunny. Setting up a Minecraft server can facilitate these activities, with affordable hosting options available. Additionally, players can recreate iconic builds from popular culture during this season.

Fake Zoom meeting “update” silently installs surveillance software

A deceptive website, uswebzoomus[.]com/zoom/, poses as a Zoom meeting platform and installs surveillance software on Windows devices without user consent. The software is a covert version of Teramind, a commercial monitoring tool. The site creates a fake Zoom waiting room experience, complete with scripted participants and background audio, to trick users into downloading a malicious file named zoomagentx64s-i(_941afee582cc71135202939296679e229dd7cced) (1).msi. This file is preconfigured to connect to an attacker-controlled Teramind server and operates in stealth mode, leaving minimal traces on the device. The installation process collects information about the device and is designed to evade detection by security tools. If users suspect they have been affected, they are advised not to open the downloaded file, check for its installation, and change passwords from a clean device.

How OpenAI Scaled to 800 Million Users on PostgreSQL

OpenAI has scaled PostgreSQL to support over 800 million active users of ChatGPT, making it one of the largest PostgreSQL deployments globally. The database can handle millions of concurrent connections and a very high volume of requests per second. OpenAI employs several strategies to optimize performance: 1. **Connection Pooling with PgBouncer**: Reduced database connections from 10,000 to 200, enhancing efficiency by a factor of 50. 2. **Read Replicas**: Distributes read requests across multiple replicas while the primary database handles writes. 3. **Horizontal Sharding**: Partitions data across multiple instances based on a shard key, such as user_id or tenant_id. 4. **Query Optimization**: Analyzes slow queries and creates appropriate indexes to maintain performance. 5. **Connection Management**: Implements timeouts and connection limits to prevent overload. 6. **Caching**: Uses application-level caching with Redis to reduce database load. 7. **Monitoring and Observability**: Tracks key metrics like connection counts and query latency to identify issues early. These strategies enable OpenAI to maintain performance and reliability for a large user base.

OpenAI Scales Single Primary Postgresql to Millions of Queries per Second for ChatGPT

OpenAI scaled PostgreSQL to handle millions of queries per second for its ChatGPT service and API, serving 800 million users. Collaborating with Azure, they optimized deployment on Azure Database for PostgreSQL, maintaining a single-primary instance with nearly 50 geo-distributed read replicas to manage read operations and keep latency low. Key optimizations included increasing instance size, refining query patterns, and directing write-heavy workloads to sharded systems like Azure Cosmos DB. OpenAI faced operational challenges such as cache-miss storms and complex multi-table joins, which they addressed by shifting tasks to the application layer, enforcing stricter timeouts, and refining query structures. They reduced write pressure on PostgreSQL by migrating shardable workloads, implementing rate-limiting, and utilizing connection pooling with PgBouncer. Future strategies include exploring cascading replication to alleviate the primary instance's load and assessing sharded PostgreSQL deployments to enhance scalability while balancing consistency and performance.

OpenAI Scales ChatGPT to 1M Queries/Second with PostgreSQL on Azure

OpenAI has optimized its database infrastructure using PostgreSQL to support 800 million monthly active users and process over a million queries per second without complex sharding. The architecture consists of a single primary instance with nearly 50 read replicas, achieving low double-digit millisecond response times at the 99th percentile. OpenAI employs best practices like connection pooling, query optimization, and strategic indexing, utilizing tools such as PgBouncer for efficient connection management. The company has achieved five-nines availability through failover mechanisms and has adapted to a tenfold increase in query volume within a year by tuning PostgreSQL parameters rather than creating custom solutions. OpenAI incorporates community-driven optimizations, such as custom indexing strategies and materialized views, and uses extensions like pgvector for managing vector data and embeddings. The organization continuously monitors for strain during traffic surges and adjusts by adding replicas or optimizing configurations. Their approach emphasizes simplicity, avoiding sharding to minimize operational overhead, and they plan to explore newer PostgreSQL features and AI-native capabilities in the future.
