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.

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.

Compulsion Games is returning to independent management amid sweeping Xbox reorganization: ‘Our immediate priority is to support our team’

Xbox has announced a restructuring initiative that will eliminate 1,600 roles within its division, contributing to a total reduction of 3,200 positions planned for the 2027 financial year. Four game development studios, including Compulsion Games, will transition out of Microsoft’s ownership, allowing Compulsion Games to regain its independence and retain ownership of its intellectual property and game catalog. Compulsion Games expressed gratitude for its time with Xbox and emphasized its commitment to supporting its team during the transition, while remaining optimistic about its future and focus on creating unique games.

How to quickly launch multiple apps with a single action in Windows 11

Windows includes a Task Scheduler for automating tasks and batch files for streamlining operations. Batch files, with a .bat extension, are plaintext scripts that execute a series of commands in sequence, useful for automating repetitive tasks. A common use is launching multiple applications simultaneously, such as Microsoft Outlook, Microsoft Teams, Google Chrome, Excel, and File Explorer, to enhance productivity. To create a batch file, users should identify the executable locations of the desired applications, create a text file named Launch Apps.bat, and input a specific script to launch the applications. The batch file can be executed by double-clicking it, and users can add echo commands for execution status or automate it with Task Scheduler. Some applications may require administrator privileges, and paths may need adjustments based on installation locations.

Linux 7.2 To Better Communicate File-System Casefolding For Helping Windows NFS & More

The Linux 7.2 kernel has introduced enhancements for reporting case-folding behavior in local file systems, allowing file servers to accurately convey their case sensitivity capabilities. Linus Torvalds merged Virtual File System (VFS) related pull requests that enable local file systems to report case-folding behavior, benefiting services like NFSD and KSMBD, particularly for Microsoft Windows NFS clients. Filesystems can now report case-insensitive and case-nonpreserving behavior through new filekattr flags in their fileattrget implementations. Supported filesystems include FAT, exFAT, NTFS3, HFS, HFS+, XFS, CIFS, NFS, VBoxSF, and ISOFS, with others defaulting to POSIX behavior. NFSd uses this information to report case folding via NFSv3 PATHCONF and implement NFSv4 attributes for case insensitivity and case preservation. The enhancements aim to improve interoperability, allowing Windows NFS clients to function correctly by reporting case-insensitivity, which streamlines operations and avoids unnecessary requests. The Linux NFS client has previously supported case-insensitive shares, requiring adjustments to caching behavior. Accurate case folding reporting is crucial for servers operating in multi-protocol environments to maintain interoperability.

EDB adds quorum commit to distributed Postgres 6.4

EDB has released version 6.4 of its Postgres Distributed (PGD) solution, which includes enhancements such as quorum commit, native connection pooling, and support for PostgreSQL large objects. The quorum commit feature ensures a unified transaction outcome across cluster nodes before finalizing a transaction, addressing potential risks from conflicting writes in distributed systems. This update targets organizations in sectors like banking, payments, telecommunications, and infrastructure, aiming to provide the same consistency guarantees previously reliant on proprietary databases. The Connection Manager now includes native connection pooling, reducing the need for external connection poolers and streamlining operations by integrating with PGD's Raft consensus layer. This integration allows for automatic route adjustments during failover and improved monitoring capabilities. Additionally, the update expands replication support to include PostgreSQL large objects, enhancing the applicability of distributed Postgres for managing mixed data sets in sectors like government, healthcare, and financial services. EDB also noted a Gartner forecast that by 2030, over 75% of enterprises in Europe and the Middle East will have repatriated workloads to their home jurisdictions, emphasizing the importance of consistent data management across locations. EDB aims to strengthen Postgres's position in the market by focusing on transaction integrity in distributed environments while minimizing reliance on additional infrastructure components.
