How we pushed CDC into Postgres, and turned replication into clockwork

Making data from transactional databases accessible to analytical databases is essential in modern data architecture, but it faces challenges such as fragile tooling, high costs, and complex operations. Snowflake has developed a Postgres service that addresses these issues by reimagining Postgres replication. Postgres is a strong operational database, but its change data capture (CDC) capabilities need improvement. Many data pipelines are fragile due to complexities in managing continuous data flow, schema changes, snapshots, and failures. To enhance user experience with Snowflake Postgres, a complete reinvention of the replication process was necessary. A new feature called data mirroring is in public preview, allowing resilient data replication into Snowflake with low cost, minimal lag, and transactional consistency. This feature directly pushes changes from Postgres into Apache Iceberg™ tables in transactional batches, which are then automatically applied to Snowflake tables without extra infrastructure. Change data capture records changes from a transactional database for replay on another system, primarily using logical decoding in Postgres. This method decodes WAL records into logical operations, but the client bears the responsibility for subsequent steps like backfilling, managing schema changes, and handling failures. Built-in logical replication in Postgres only addresses some complexities. A limitation of logical decoding is that the external system does not recognize the state of Postgres, making it difficult to detect schema changes or correlate snapshots with changes. The solution is to push changes from Postgres into a data lake, specifically into Iceberg tables using compressed Parquet format, with object stores like Amazon S3 as the destination. The mirroring process uses a new Postgres extension called snowflake_cdc, which continuously pushes batches of changes into per-table change logs and a meta log. This extension understands the Postgres environment, coordinating schema changes and complex transactions while ensuring alignment between snapshots and changes.

Windows 11 – The system restore that also includes your files

Since June 23, Microsoft has been implementing a point-in-time restore feature on Windows 11, which is enabled by default for Home and Pro editions when the system drive exceeds 200 GB. This feature captures a complete snapshot of the machine approximately every 24 hours using the Volume Shadow Copy service, including system, applications, settings, and local files. Users can revert to a previous state in case of issues, but restoring from a snapshot older than 48 hours will erase all changes made since then, except for OneDrive data. The feature retains snapshots for up to 72 hours and reserves 2% of drive space, capped at 50 GB. If free space drops below 20 GB, older snapshots are deleted. Restoration occurs locally through WinRE, and users need a BitLocker recovery key if the drive is encrypted. After a restore, the feature pauses and requires user consent to resume. Snapshots from upgraded editions are not accessible, and only the Enterprise edition allows adjustments to snapshot settings. The feature can be disabled in system settings. It is not a backup solution, and users are advised to maintain separate backups for important files.

Active Exploitation Alert: Fake Bahrain Alert App Deploys Advanced Android Surveillance Malware Targeting Gulf Region Users

A cyber-espionage campaign has been identified involving a counterfeit Bahrain Alert Android application designed to surveil individuals in Bahrain and the Gulf region. The app masquerades as an official civil defense tool and employs social engineering tactics to compromise Android devices, extract sensitive data, and maintain remote access. It targets high-value individuals such as activists and journalists, particularly during civil unrest and missile alerts, leveraging trusted government branding to increase infection rates. The malware features a complex, multi-stage architecture with advanced evasion techniques and is distributed through phishing links and malicious websites. It initiates a four-stage infection process, ultimately installing a remote access trojan (RAT) that enables covert surveillance and encrypted communications. The malware can monitor device activity, capture credentials, and intercept communications, while also employing mechanisms to avoid detection and maintain persistence. The campaign primarily targets Bahraini citizens, exploiting fear during crises to encourage app installation. Although there are indications of Russian-speaking developers involved, there is no definitive attribution to a specific nation-state or APT group. Mitigation strategies include monitoring for suspicious app installations, user education on verifying app authenticity, and blocking known malicious domains.

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.

Tomb Raider Legacy of Atlantis needs to have this one thing or it won’t feel right

Ava enjoys immersive RPGs, MMOs, and cozy games, particularly The Sims and Dead by Daylight. The upcoming Tomb Raider game, Legacy of Atlantis, features a quote from Lara Croft's ancestor, T.E. Croft, about the burden of legacy, which resonates with fans. Anticipation for the game increased after a mini-documentary was released on July 20, with developers Crystal Dynamics and Flying Wild Hog focusing on honoring Lara's character and movement. Lead Gameplay Designer Bartek Schweiger emphasized the importance of reflecting on the series' past. Fans are eager for the return of Croft Manor, which has not been represented in a way that evokes nostalgia since earlier games. The manor provided a space for players to practice skills and has memorable elements, such as the obstacle course and the music. Legacy of Atlantis aims to unify Lara's timeline and reintroduce Croft Manor to both veteran fans and newcomers. The mini-documentary highlights the return of Charlie the fish, a character from TR Anniversary, indicating the developers' commitment to the series' legacy. Creative Director Mikał Kuk and Game Director Raul Siqueira discussed the significance of Charlie and Lara's acrobatics, suggesting a thoughtful approach to her character development and the potential for Croft Manor to play a key role in the game.

A modder has brought No Man’s Sky-style seamless takeoffs to Starfield, and even in beta they look pretty great

Bethesda's space RPG, Starfield, faces challenges due to frequent loading screens that disrupt the gameplay experience. A mod called Seamless Planet Takeoffs aims to enhance the takeoff experience by allowing players to remain in the cockpit during launch, providing a more immersive transition. The mod is still in beta and does not completely eliminate loading screens but improves the experience by masking transitions. The creator, 0xBobby, notes that while the mod enhances takeoff fluidity based on atmospheric conditions, seamless landings remain difficult to achieve and may not be possible.
