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.

Sixteen years ago, the author began their PhD at UC Berkeley, where they were advised to focus on analytics rather than OLTP databases, which were considered a solved problem. However, upon developing Databricks, they found that OLTP databases were cumbersome, challenging to scale, and fragile. This led to the creation of Lakebase, a serverless Postgres database designed to address these issues by externalizing the write-ahead log (WAL) and data files into independent services. Lakebase architecture separates the WAL into a distributed service called SafeKeeper and data files into another service called PageServer, allowing for improved durability, scalability, and performance. This architecture eliminates data loss risks associated with disk failures and misconfigurations, simplifies high availability, and allows for elastic compute resources. Lakebase also introduces LTAP (Lake Transactional/Analytical Processing), which enables transactions and analytics to operate on a single data copy in real-time, avoiding the need for separate data copies and reducing costs. The system retains Postgres's ACID semantics while storing data in open columnar formats, making it accessible to both transactional and analytical engines without the delays and complexities of traditional replication methods. The architecture allows for unlimited storage, serverless compute, and instant branching, while ensuring that analytics can read the most current transactional data without affecting transactional workloads. LTAP aims to unify transactional and analytical processing by leveraging distinct compute engines for each workload while integrating at the storage layer.

Making Windows a developer platform, again

Setting up a PC with the base Dev Config has been streamlined for developers, utilizing the Winget configuration service to install applications, execute updates, and apply developer settings on Windows. Users can access setup scripts by cloning a GitHub repository or downloading a zip archive, with clear instructions provided by Microsoft. The installation may require a reboot during the Windows Subsystem for Linux (WSL) installation, but the script resumes automatically afterward. The process installs applications such as PowerShell, Git, GitHub command-line interfaces, Windows App SDK, Visual Studio Code, and language support for Node.js, Python, and .NET. It also includes developer-friendly fonts and a theme engine for Windows Terminal, along with options for customizing File Explorer and the Windows Task Bar. After WSL installation, developers can use WSL Comfort scripts to install additional tools and personalize their Windows Terminal experience. This utility has two phases: the Windows component configures WSL and Ubuntu, while the Linux component fine-tunes the WSL environment, allowing for zsh and starship terminal display tools. It also integrates popular command-line interfaces and supports the Homebrew package installer, targeting existing Ubuntu instances without needing a new Linux distribution installation.

Automate Amazon Aurora PostgreSQL major or minor version upgrade using AWS Systems Manager and Amazon EC2

Managing upgrades for the Aurora PostgreSQL-Compatible Edition can be labor-intensive and error-prone when done manually. Automating Amazon Aurora PostgreSQL upgrades can reduce manual effort by up to 80% and minimize downtime risks through consistent procedures. The automation solution uses AWS Systems Manager, Amazon EC2, and AWS Secrets Manager, structured around two modules: PREUPGRADE for readiness checks and UPGRADE for the actual upgrade process. The solution identifies upgrade candidates using database tags, creates safety backups with Copy-on-Write clones, manages the upgrade process with minimal human intervention, and offers real-time monitoring and email notifications. The workflow includes logging into the Systems Manager console, downloading the upgrade script, identifying Aurora PostgreSQL clusters based on tags, retrieving credentials from AWS Secrets Manager, executing pre-upgrade checks or upgrades, uploading log files to Amazon S3, and sending email notifications via Amazon SNS. Prerequisites include familiarity with the Aurora upgrade process, appropriate IAM permissions, creating a maintenance user, setting up AWS Secrets Manager, tagging Aurora clusters, creating an S3 bucket, and configuring an SNS topic for notifications. Implementation steps involve reviewing setup instructions, uploading the upgrade script to S3, creating an AWS Systems Manager automation document, executing the automation document, and monitoring the upgrade process through logs generated during pre-upgrade and upgrade phases. The logs provide detailed information on tasks performed, including replication slot status and configuration backups. After testing, it is recommended to clean up resources to avoid future charges.

Fake ChatGPT download site infects Windows and Mac users with malware

A counterfeit website, openew[.]app, is impersonating OpenAI's official ChatGPT download page and distributing malware. Windows users who download from this site receive a credential-stealing malware loader, while macOS users are infected with Odyssey Stealer, a variant associated with cryptocurrency theft. The fake site mimics the legitimate ChatGPT interface and uses HTTPS to appear trustworthy. The Windows malware, Chat_GPT.exe, creates a back channel to an attacker-controlled server, while the macOS malware captures sensitive data and attempts to replace legitimate cryptocurrency wallet applications with compromised versions. Users who download from official sources remain safe, but those who click on ads or unfamiliar links risk compromising their online accounts and sensitive information. Malwarebytes offers protection against this malware. Indicators of compromise include specific file hashes and network indicators associated with the malicious site.

How I Changed the SID on My Windows Server Without Reinstalling (And Why You Should Care)

Cloning a Windows Server machine can lead to issues with duplicate Security Identifiers (SIDs). A Security Identifier (SID) is a unique string assigned to every machine, user, and group in Windows, functioning like a fingerprint. Duplicate SIDs can cause problems such as domain join failures, incorrect WSUS reporting, inconsistent Group Policy application, and licensing issues. The author initially attempted to use sysprep to change the SID after cloning, which resulted in stripping the domain join and causing SQL Server to fail. The author then discovered Wittytool Disk Clone, which includes a SID changer that successfully generated a new SID and updated all necessary references without disrupting the server's configuration or applications. The process took only six minutes and worked similarly on Windows Server 2019. It is more efficient to generate a new SID during the cloning process rather than afterward. Important precautions include taking a snapshot or backup before making changes and being aware that changing the SID on domain controllers is more complex. Reactivation of Windows may also be required after the SID change.
