Postgres and the Lakehouse Are Becoming One System — Here’s What Comes Next

Developers are increasingly using Postgres for application needs alongside lakehouse technologies for analytics and data science. Postgres has evolved into a versatile operational database suitable for various applications, while lakehouse technologies enable organizations to manage and analyze large-scale data efficiently. There is a growing synergy between these systems, although they often operate in silos managed by different teams. An emerging architectural paradigm views Postgres and lakehouses as complementary layers within a modular framework to address both operational and analytical requirements. Historically, OLTP systems were used for transactions and OLAP systems for analysis, but this model is shifting. Scenarios such as financial applications requiring real-time risk reports and SaaS applications calculating usage metrics are becoming standard. Effective communication between product-engineering teams managing operational systems and data teams overseeing lakehouse services is essential for enhancing system resilience. A trend called operational medallion architecture incorporates bronze, silver, and gold layers for real-time and user-facing systems. The bronze layer consists of raw data, the silver layer contains cleaned data in Postgres for real-time analytics, and the gold layer features pre-aggregated data for low-latency experiences. Each layer is queryable, allowing for bidirectional data movement between S3 and Postgres. Key developments facilitating the integration of operational databases and lakehouses include the maturation of Iceberg as a flexible table format, the evolution of Postgres with support for various data types and querying capabilities, and a growing demand for composability among developers. The market is moving towards modular, open, and developer-friendly architectures that integrate operational and analytical layers. Future data infrastructure will focus on interconnected components and coherent modern data architecture that serves both operational and non-operational use cases seamlessly.

Lakebase Is Databricks’ Fully-Managed Postgres Database for the AI Era

Databricks has launched Lakebase, a fully-managed serverless Postgres database, following its acquisition of Neon. Lakebase combines the extensibility of Postgres with a modern serverless architecture, facilitating a unified data experience for developing data-driven applications while reducing operational complexities. Its core feature is the separation of storage and compute, allowing it to use cost-effective object storage for scalability and high availability, with low-latency access and high-concurrency transactions. Lakebase is built on open standards, making it a versatile relational database that integrates with the Databricks Platform for enhanced observability, security, and governance. Prior to the acquisition, 80% of databases on Neon were created by AI agents, and Lakebase's features are designed to support AI agents in problem-solving. Lakebase is currently in public preview.

PostgreSQL 18 Delivers Significant Performance Gains for OLTP and Analytics

PostgreSQL 18, set to debut in September, is currently in its Beta 1 phase and introduces new features aimed at enhancing analytics and transactional capabilities. Key improvements include asynchronous inputs for handling multiple read requests simultaneously, advancements in query optimization such as better handling of OR clauses and skip scans, and accelerated creation of Generalized Inverted Indexes (GINs) through parallel processing. The release also simplifies the integration of non-natively supported indices, allowing organizations to develop and adopt new indexes as extensions. Overall, PostgreSQL 18 is designed to improve performance for high-volume environments, particularly in cloud settings.

Developer Made Minecraft Run On Nintendo 64

Arthurtilly has developed a Minecraft-style voxel engine within the Super Mario 64 engine, functioning on authentic Nintendo 64 hardware. The engine utilizes advanced multithreading techniques for efficient terrain and mesh generation, providing smooth performance. It features an infinite world with various block types, diverse biomes, and early elements like fluids and sophisticated lighting effects. Future updates will enhance the engine with flowing water and lava, an improved lighting system with a dynamic day/night cycle, full support for saving and loading worlds, terrain features like trees and vegetation, and an inventory system. A demonstration of the engine is available on a genuine Nintendo 64 console.

Meet Xata Agent: An Open Source Agent for Proactive PostgreSQL Monitoring, Automated Troubleshooting, and Seamless DevOps Integration

Xata Agent is an open-source AI assistant designed for PostgreSQL database site reliability engineering. It monitors logs and performance metrics to identify issues like slow queries and unusual connection counts, helping to maintain database integrity and performance. The tool automates tasks such as vacuuming and indexing and provides actionable recommendations through diagnostic playbooks and read-only SQL routines. The architecture is built as a Next.js application using TypeScript, organized in a monorepo structure. Developers can set up their environment using Node, install dependencies, and configure a local PostgreSQL instance with Docker Compose. Production deployment involves using Docker images and configuring environment variables in a production file. Key functionalities include proactive monitoring, configuration tuning, performance troubleshooting, safe diagnostics, cloud integration, alerting, LLM flexibility, and playbook customization. Developers can create new tools and integrate them into playbooks for cohesive workflows. Future plans include custom playbooks, support for Model Context Protocol, evaluation harnesses, approval workflows, and a managed cloud edition. The architecture promotes extensibility and community contributions, standardizing incident response and reducing human error in database management.

Improve PostgreSQL performance using the pgstattuple extension

PostgreSQL is an open-source relational database management system known for its extensibility, which allows developers to enhance its capabilities through various extensions and plugins. The pgstattuple extension provides detailed statistics at the tuple level from PostgreSQL tables and indexes, revealing key metrics such as the number of live tuples, dead tuples, average length of live tuples, total free space, and percentages of free space and dead tuples. These metrics help database administrators identify potential health and performance issues, such as excessive table bloat or index fragmentation. Both Amazon Aurora and Amazon RDS support the pgstattuple extension, which can be activated using the command CREATE EXTENSION pgstattuple;. Functions like pgstattuple(relation) and pgstatindex(index) can be used to analyze physical storage and index statistics. Bloat occurs when unused space is left behind after UPDATE and DELETE operations, and the autovacuum process in PostgreSQL automates the cleanup of dead tuples. However, if autovacuum fails, manual intervention may be necessary. Regular monitoring of bloat is essential for maintaining performance, and metrics from pgstattuple can help optimize autovacuum settings. The pg_cron extension can automate VACUUM operations to manage bloat proactively. Index bloat can also be detected using pgstatindex, and significantly bloated indexes can be rebuilt using REINDEX or pg_repack. Best practices for using pgstattuple include estimating bloat with check_postgres, analyzing physical storage, monitoring dead_tuple_percent, and avoiding interference on highly active tables.
