Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

Microsoft’s July update is blocked on some Dell PCs. Here’s why

Microsoft's July update, KB5101650, is temporarily withheld for certain Dell PCs using Intel Innovation Platform Framework (IPF) drivers due to compatibility issues. Affected devices are experiencing performance problems such as crashes, reduced efficiency, overheating, and battery drain. Microsoft has acknowledged the incompatibility and is working on a fix, expecting to release the update for affected devices soon. The issues may be linked to the optional June update, KB5095093, which was not widely adopted. Specific Dell models impacted by these issues have not been disclosed.

What Is Serverless PostgreSQL?

Serverless PostgreSQL is a fully managed cloud database model that separates compute and storage, allowing them to scale independently and automatically based on demand. It eliminates the need for manual infrastructure provisioning and capacity planning, charging only for active usage. Unlike traditional PostgreSQL setups, which require continuous resource allocation and manual scaling, serverless PostgreSQL provisions resources on demand and can scale down to zero during idle periods. Serverless PostgreSQL integrates with serverless compute platforms, enabling analytical queries to access the same data within a unified architecture. Key differences between traditional and serverless PostgreSQL include manual versus automatic provisioning and scaling, fixed versus usage-based billing, and high versus reduced operational overhead. Lakebase architecture is an emerging model that combines transactional databases with lakehouse foundations, allowing operational and analytical workloads to coexist on a single platform. This architecture minimizes data duplication and simplifies access, enhancing data management and analysis. Serverless PostgreSQL operates on a cloud-native architecture that enhances efficiency by allowing compute and storage to scale autonomously. It features scale-to-zero behavior, where compute resources are suspended when inactive and reactivated upon new queries. Major providers include Databricks Lakebase, Amazon Aurora Serverless v2, and Neon, each offering varying capabilities and integrations. Pricing for serverless PostgreSQL typically includes charges for compute resources, storage, and data transfer, with costs fluctuating based on workload activity. Cold start latency is a performance consideration, as reactivating compute resources can introduce delays. Strategies to mitigate this include keeping resources partially active or selecting providers with minimal cold start impacts. Serverless PostgreSQL is well-suited for OLTP workloads, while lakebase architecture is better for AI development, variable workloads, and environments requiring rapid iteration. Setting up serverless PostgreSQL involves choosing a provider, creating a database instance, and configuring access settings. It can also be used alongside serverless compute platforms for analytics, further extending its capabilities.

Microsoft needs to “reset Xbox,” says Asha Sharma, as the company lays off 3,200 employees

Xbox plans to reduce its workforce by approximately 3,200 employees by the end of the fiscal year on June 30, 2027, with an initial layoff of around 1,600 positions. CEO Asha Sharma expressed concerns about the company's health and announced a transition of four studios to new management. Xbox is facing financial challenges, operating at margins significantly lower than comparable entities, and the expected growth of Game Pass has not occurred. Compulsion Games and Double Fine Productions will return to independent status, retaining ownership of their intellectual properties. Ninja Theory and Undead Labs will also join new ownership structures. Bethesda is refocusing on its major franchises, and there are no cancellations of first-party games due to these reductions. Compulsion Games and Double Fine Productions expressed gratitude for support during this transition.

EDB converges analytics on Postgres to support AI agents

EDB's per-core pricing model offers predictable costs compared to consumption-based cloud data platforms, aiding organizations in budgeting. However, predictable billing does not guarantee lower costs, as high-speed operational data processing requires more expensive hardware than lakehouse storage solutions. EDB's architecture, built on a unified Postgres-Iceberg foundation, streamlines data governance by reducing the need for multiple specialized data stores, leading to fewer platforms to manage and enhancing operational efficiency and data governance protocols.

PostgreSQL 18 on Amazon Aurora and Amazon RDS: Security, monitoring, and developer enhancements

PostgreSQL version 18 has deprecated MD5 password authentication in favor of SCRAM-SHA-256, with a new parameter, md5_password_warnings, enabled by default to log deprecation warnings. It has enhanced monitoring capabilities by adding columns to pg_stat_database and pg_stat_statements to track parallel worker activity, with the default max_parallel_workers_per_gather set to 0 in Aurora PostgreSQL. The pg_stat_subscription_stats view now includes new columns for tracking conflict types in logical replication. Optimizer statistics are automatically transferred during upgrades, while uuidv7() generates timestamp-ordered UUIDs. The default streaming option for CREATE SUBSCRIPTION has changed to parallel, and the idle_replication_slot_timeout parameter automatically invalidates inactive replication slots. Enhancements to the COPY command include REJECT_LIMIT for error tolerance and a silent LOG_VERBOSITY level. OLD and NEW aliases have been introduced in RETURNING clauses for various DML commands.
