From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

Google App Update: A Stunning Gemini AI Upgrade For Mac Users

Google is developing a feature that allows Android users to remotely command and monitor AI workflows on their Macs through the Android Google app. This feature is linked to Gemini Spark, Google's AI agent, and includes a "new thread" system to prevent data leakage. The upgrade aims to create a cross-platform ecosystem for Android users to utilize AI capabilities on Apple-silicon Macs. The feature, internally codenamed "Robin," requires Gemini for macOS to be installed on Apple-silicon devices and allows users to perform tasks like summarizing PDFs or triggering scripts remotely. This functionality is currently exclusive to Mac users, providing them an advantage over Windows users who lack a standalone Gemini desktop client. The Gemini Spark AI framework is still in an experimental stage, and its performance on macOS has yet to be fully validated.

Bypassed Windows 11 shows surprising stability on ancient, completely unsupported hardware

Windows 11 has elevated system requirements, necessitating four times the memory and storage for AI-driven applications. It can technically run on a minimum of 4GB of memory, but current hardware pricing is challenging due to a silicon shortage affecting various memory types. A retro hardware enthusiast named Omores installed Windows 11 on a DDR1-based system using an ASRock ConRoe865PE motherboard, Intel Core 2 Quad Q6600 processor, 3GB of DDR1 RAM, and an ATI Radeon HD 4650 AGP graphics card. He overcame the lack of AGP support in Windows 11 by using legacy drivers, achieving satisfactory performance for older applications and games. However, Windows 11 version 24H2 requires SSE4.2 CPU instructions, which are not supported by processors from the AGP era, making version 23H2 the last compatible release for such systems.

PlayStation’s PC port era appears over as Sony scrubs key policy language

Sony's recent annual business report indicates a shift in its strategy for first-party titles, removing the previous commitment to release PlayStation games on PC after console launches. Analysts suggest this change signals a focus on PS5 exclusivity for upcoming single-player titles. Reports have indicated that future games like Ghost of Yotei, Saros, and Marvel’s Wolverine may remain exclusive to the PS5. Additionally, the report highlights Sony's commitment to integrating artificial intelligence in game development to enhance creativity. The company has also revised its business outlook, removing the term "profitable" due to ongoing supply chain challenges and rising hardware costs, which have affected its ability to expand the PS5 installed base.

Google VP John Maletis confirms Googlebooks will run Android apps far better than Chromebooks

Chrome Unboxed offers a membership called Chrome Unboxed Plus, which provides an ad-free experience, access to a private Discord, and additional perks. Google is developing the Googlebook category directly on the Android tech stack, allowing apps to run natively without an emulation layer, significantly improving performance. This change enables applications to utilize hardware capabilities fully, resulting in a smoother user experience. The unified foundation of Googlebooks encourages developers to optimize their apps for various devices, facilitating a "Build Once, Deploy Anywhere" approach. This shift has led to increased enthusiasm among developers, with many creating integrations specifically for Googlebooks. The success of Googlebooks will depend on effective software execution, as it aims to provide high-speed performance without the limitations of traditional operating systems.
