  1. Trino JDBC driver

    1일 전

    Trino JDBC driver

    Trino JDBC driver, a critical bridge that allows standard Java applications and BI tools to interact with Trino’s distributed SQL engine. While the driver offers wide compatibility with the JDBC 4.2 specification, it faces an architectural challenge known as the JDBC bottleneck, where single-threaded serialization limits data ingestion speeds from relational sources. To mitigate this, the sources suggest optimization strategies such as parallel extraction, operator pushdown, and the use of the Spooling protocol to bypass the coordinator node. The documentation further compares Trino to other engines like Apache Spark and Drill, highlighting its superior performance for federated querying across massive, disparate data lakes. Beyond technical mechanics, the text outlines enterprise use cases in finance and healthcare while discussing future performance enhancements through Project Hummingbird. Ultimately, the driver is presented as an essential component for modern Data Mesh and Lakehouse architectures that require high-velocity, secure data access.

    SAP’s 2025–2026 strategic transition

    SAP’s 2025–2026 strategic transition from traditional business software toward an "Autonomous Enterprise" powered by agentic AI. Central to this evolution is the transformation of the Joule assistant into an orchestrator of independent digital agents and the introduction of SAP-RPT-1, a specialized model for tabular data. To achieve this, the company emphasizes a "Clean Core" architecture, requiring clients to eliminate custom code to ensure AI reliability and data integrity. The report also compares SAP's premium, tiered pricing and federated data approach against the strategies of major rivals like Oracle and Workday. While SAP leverages deep industry expertise and partnerships with firms like NVIDIA and Perplexity, it faces significant hurdles including market volatility, customer technical debt, and a shortage of skilled implementation experts. Ultimately, the sources suggest that SAP’s future depends on successfully grounding autonomous agents in its proprietary Knowledge Graph to prevent operational errors.

    CrowdStrike Falcon Shield: SaaS Security and Unified XDR Analysis

    Analysis of CrowdStrike Falcon Shield, a platform designed to secure the modern enterprise's expanded software-as-a-service (SaaS) landscape, which has replaced the traditional network perimeter. The document explains that Falcon Shield, built upon the acquisition of Adaptive Shield, unifies SaaS Security Posture Management (SSPM) with Identity Threat Detection and Response (ITDR) by leveraging an API-first architecture and integrating endpoint telemetry from the Falcon sensor. Crucially, the analysis details the platform’s core capabilities, including continuous configuration auditing, identity governance to combat permission creep, and advanced threat detection of "malware-free" attacks that exploit compromised credentials. Finally, the text positions Falcon Shield competitively against rivals like Microsoft and AppOmni while exploring its utility in addressing emerging risks, such as Shadow AI discovery and GenAI governance.

  4. Raw Disk Access and the Subversion of EDR Visibility

    Raw Disk Access and the Subversion of EDR Visibility

    Source: https://medium.com/workday-engineering/leveraging-raw-disk-reads-to-bypass-edr-f145838b0e6d Author : Christopher EllisAnalysis of a highly advanced Endpoint Detection and Response (EDR) evasion technique that leverages raw disk reads to bypass security monitoring. It explains that EDR systems rely on hooking high-level Operating System (OS) Application Programming Interfaces (APIs) to gain visibility, but raw disk access circumvents this by interacting directly with low-level disk drivers. The report details the attack mechanics, which often require kernel-level privilege escalation via the Bring Your Own Vulnerable Driver (BYOVD) method, allowing attackers to reconstruct sensitive files like credential stores without triggering file access logs. Furthermore, the text outlines robust defense-in-depth strategies, emphasizing the need for Full-Disk Encryption (FDE) and deploying specialized low-level monitoring tools like Sysmon to detect the resulting "RawAccessRead" events. Ultimately, the source argues that defense must shift toward hardware-assisted security to counter the trend of adversaries moving "down the stack."

  5. Cloud ERP Finance Analysis and Strategic Guide 2025

    2025. 10. 31.

    Cloud ERP Finance Analysis and Strategic Guide 2025

    Strategic analysis of the Cloud ERP Finance market, primarily focusing on the 2025 Gartner Magic Quadrant. It details the pivotal market shift driven by the aggressive integration of Artificial Intelligence (AI), automation, and composable architectures, which transforms core financial operations. The document breaks down Gartner’s methodology for evaluating vendors based on their "Ability to Execute" and "Completeness of Vision" and profiles the competitive positioning of major players like Workday, Microsoft, SAP, and Oracle. Crucially, the analysis offers strategic recommendations for organizations, emphasizing the need for rigorous Total Cost of Ownership (TCO) modeling and substantial investment in change management to successfully navigate complex cloud ERP implementations and realize the competitive advantages promised by AI.

  6. Query Engines and Apache Iceberg Lakehouse Ecosystem

    2025. 10. 09.

    Query Engines and Apache Iceberg Lakehouse Ecosystem

    Modern data lakehouse architecture, which resolves the shortcomings of earlier data lakes by integrating data warehouse features. Central to this new paradigm is Apache Iceberg, an open table format that sits atop low-cost cloud object storage, enabling crucial features like ACID transactions, safe schema evolution, and high-performance querying through a sophisticated metadata layer. The text thoroughly details Iceberg's three-layer architecture—Catalog, Metadata, and Data—and contrasts it with the physical foundation provided by scalable object storage and efficient columnar file formats like Parquet and ORC. Finally, the analysis explores the diverse compute ecosystem, profiling specialized query engines—including Spark for ETL, Trino for interactive analytics, Flink for streaming, and managed platforms like Snowflake and Dremio—that leverage Iceberg's open standard to operate concurrently on a single, consistent data source.

  7. JDBC for Cloud SaaS Queries

    2025. 09. 18.

    JDBC for Cloud SaaS Queries

    Java Database Connectivity (JDBC) for querying Cloud Software as a Service (SaaS) databases over the internet. It explores the architectural framework of JDBC, including its core components and the evolution of driver types, emphasizing the suitability of Type 4 drivers for cloud environments. The text details the benefits and challenges of using JDBC in a cloud SaaS paradigm, focusing on performance issues due to network latency and the critical need for robust security measures in a zero-trust internet environment. Furthermore, it outlines optimization techniques like connection pooling and batch updates, discusses security fortifications such as SSL/TLS and VPCs, compares JDBC with other connectivity solutions like ODBC and REST, and examines the future of cloud database connectivity, including serverless architectures and data APIs.
