Building a Scalable Usage Insights Platform with Delta Sharing x.com/i/broadcasts/1…

The Next Evolution of Delta Lake: Catalog-Managed Tables 🚀 We are excited to share that 𝗗𝗲𝗹𝘁𝗮 𝗟𝗮𝗸𝗲 𝟰.𝟭.𝟬 introduces 𝗰𝗮𝘁𝗮𝗹𝗼𝗴-𝗺𝗮𝗻𝗮𝗴𝗲𝗱 𝘁𝗮𝗯𝗹𝗲𝘀, which establish the catalog as the coordinator of table access and source of truth for table state! This evolution simplifies discovery and governance while unlocking significant performance gains. 🔹 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱𝗶𝘇𝗲𝗱 𝘁𝗮𝗯𝗹𝗲 𝗱𝗶𝘀𝗰𝗼𝘃𝗲𝗿𝘆 𝗮𝗻𝗱 𝘂𝗻𝗶𝗳𝗶𝗲𝗱 𝗴𝗼𝘃𝗲𝗿𝗻𝗮𝗻𝗰𝗲: The catalog facilitates access through logical table identifiers and grants clients appropriate permissions to data, dramatically simplifying how engines discover and use tables in a governed manner. 🔹 𝗘𝗻𝗳𝗼𝗿𝗰𝗲𝗮𝗯𝗹𝗲 𝗰𝗼𝗻𝘀𝘁𝗿𝗮𝗶𝗻𝘁𝘀: The catalog can authoritatively validate or reject schema and constraint changes, preventing incompatible updates that could compromise data integrity or break downstream workloads. 🔹 𝗢𝗽𝗲𝗻 𝗳𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻: This design aligns Delta with the catalog-managed model pioneered by Apache Iceberg, making it simpler for practitioners to discover and govern data consistently regardless of format.

📣 Engineering Dynamic Lineage: Column-level lineage using @OpenLineage, @ApacheSpark , and Delta Lake Traditional static lineage tools fail to track real-time data flow in complex enterprise environments. Join us as we explore 𝗱𝘆𝗻𝗮𝗺𝗶𝗰, 𝗱𝗲𝘁𝗲𝗿𝗺𝗶𝗻𝗶𝘀𝘁𝗶𝗰 𝗹𝗶𝗻𝗲𝗮𝗴𝗲 𝗮𝘀 𝘁𝗲𝗹𝗲𝗺𝗲𝘁𝗿𝘆—treating query execution as parseable events that reveal current data state. 𝗪𝗲'𝗹𝗹 𝗰𝗼𝘃𝗲𝗿: 🔹 Dynamic, deterministic lineage vs. static maps 🔹 OpenLineage as the open source alternative to proprietary solutions 🔹 Stitching flows across 1000s of jobs via Spark listeners 🔹 Integrating lineage alongside tables in the Lakehouse 🔗 Register: luma.com/delta-0224 🗓️ Feb 24 | 9AM PT 📺 Live on LinkedIn, YouTube & X #opensource #oss #deltalake #telemetry #openlineage #apachespark

#OneLake interoperability with @Snowflake is now GA. Built on open standards like Apache Iceberg, this offers less duplication and more flexibility across #MicrosoftFabric + Snowflake. I also sat down with Christian Kleinerman, EVP Product, Snowflake to talk through what this enables and where the industry is headed. 🔗Check out our blog and video: tinyurl.com/43de92mu

Loved joining @KratosBi on his podcast. Unified data is not optional for AI. Trusted semantics turn insight into action. Platforms must reduce friction so teams can move faster with confidence. #MicrosoftFabric #OneLake #PowerBI tinyurl.com/upbxymn4

AI success starts with data—but building reliable pipelines shouldn't feel like rocket science. 🚀 It is time to cut through the complexity. Join Andrew Sitz to learn how to build production-grade pipelines using the first principles of software and data engineering. Discover how to bridge the gap between traditional SQL thinking and modern Delta Lake and PySpark patterns. 🙌 Walk away with a clear framework for writing cleaner, more maintainable pipelines. 🕓 9AM PT 🗓️ February 11 🔗 RSVP: luma.com/deltahacks-0211 #opensource #deltalake #oss #ai

Unify your graph and lakehouse worlds in one stack. 🙌✅ 🗓️ January 21 🕓 9:00AM PT 🔗 RSVP: luma.com/OLAI-121 See how Delta Lake + @puppyquery let you run Cypher and Gremlin queries, multi-hop analytics, and graph visualizations directly on your existing tables—without moving data off your lakehouse or maintaining duplicate systems. From attack-path analysis in security to transaction flows in finance and complex supply chains, learn how relationship-native analytics can unlock insights your standard SQL queries miss. #opensource #oss #deltalake #puppygraph #openlakehouse #lakehouse

🚨 STOP moving & duplicating data for graph analytics! Graph workloads (security, finance, supply chain) often require a separate graph DB, leading to constant data movement & pipeline headaches. 🤯 What if you could run powerful, relationship-driven analytics directly on your Delta Lake data? 🤔 Introducing the 𝗚𝗿𝗮𝗽𝗵 𝗟𝗮𝗸𝗲𝗵𝗼𝘂𝘀𝗲, built with Delta Lake and @puppyquery. In this webinar, we'll demonstrate: 🔹 Querying Delta Lake tables as graphs. 🔹 Performing complex multi-hop analytics using Cypher and Gremlin. 🔹 Visualizing your tabular data as interconnected graph structures. 🗓️ January 21, 2026 ⏰ 9:00 AM PT ➡️ Register: luma.com/OLAI-121 #puppygraph #deltalake #opensource #oss #lakehouse

🎉 It’s been one year since the release of 𝗗𝗲𝗹𝘁𝗮 𝗟𝗮𝗸𝗲: 𝗧𝗵𝗲 𝗗𝗲𝗳𝗶𝗻𝗶𝘁𝗶𝘃𝗲 𝗚𝘂𝗶𝗱𝗲, and we’re throwing a virtual party to celebrate the milestone! 🔗 Register: luma.com/1yearcelebrati… 🔹 𝗖𝗲𝗹𝗲𝗯𝗿𝗮𝘁𝗲 𝘁𝗵𝗲 𝗗𝗲𝗳𝗶𝗻𝗶𝘁𝗶𝘃𝗲 𝗚𝘂𝗶𝗱𝗲: Let's toast to a year of community growth and adoption. 🔹 𝗔𝘀𝗸 𝗨𝘀 𝗔𝗻𝘆𝘁𝗵𝗶𝗻𝗴 (𝗔𝗨𝗔): Whether you're a beginner or an advanced user, bring your toughest Delta Lake questions! 🔹 𝗦𝘄𝗮𝗴 𝗔𝗹𝗲𝗿𝘁: We'll be giving away exclusive Delta Lake swag! 📅 December 17 ⏰ 9:00AM PT / 12:00PM ET #deltalake #opensource #oss #lakehouse @dennylee @newfront

✨Pinpoint Outliers in Power BI Show exactly where your data goes above or below target - with native visuals only. Step 1: Build your base line chart Add Value and Target measures. Step 2: Add visual calculations for markers Create two: one for values above target, one for below. These will show the deviation points. Step 3: Add labels and style Label the two marker series (Above / Below target). Hide markers on the main line and make outlier markers larger. Step 4: Connect to target Use error bars to draw a subtle line from each outlier to its target value. #powerbi #outliers #visualization #report #design Want to design outstanding reports?
