CDC overview and benefits Building on this foundation, Change Data Capture (CDC) is the pattern we use to propagate only the rows that changed from transactional systems into analytics stores, and it’s the fastest route to keep data fresh in Databricks-driven data pipelines. CDC captures inserts, updates, and deletes at

Why AI Analytics Matters If you’ve ever stared at dashboards that show what happened last quarter and wondered how to act now, you’re not alone. AI analytics puts predictive analytics and real-time analytics into your operational flow so you can move from reactive reporting to proactive decision-making. How do you

Why df.equals() fails If you’ve ever written a quick sanity check like df1.equals(df2) and then been surprised by a False, you’re not alone — df.equals() is a strict, label-and-type-sensitive comparison and often fails for reasons that matter less in real-world validation. In the first 100 words we want to emphasize

Indexing Fundamentals If your queries are slow, the first place to investigate is often SQL indexing, because an appropriate index turns expensive table scans into targeted lookups and directly impacts query planning and performance optimization. An index is a data structure that maps key values to row locations so the

AI Voice Assistants Overview AI voice assistants and voicebots are the first line of interaction in modern call centers, absorbing routine volume, shortening wait times, and routing complex issues to human agents. In the next bite of the architecture we’ll unpack, these systems must reliably recognize speech, infer user intent,

Overview: AI Voice Assistants for Call Centers When contact volume spikes, the first thing your customers notice is the hold music—what they don’t see is the operational drag behind it. AI voice assistants front-load this problem by automating routine interactions, routing complex issues to agents, and helping you reduce wait

Define hardware constraints and goals When you try to run large language models on small hardware, the first mistake is treating the device as a black box instead of profiling it. If your objective is to deploy LLMs on edge devices or low-resource systems, you must front-load concrete constraints and

Problem Overview and Goals Reinforcement learning and Tic-Tac-Toe are a compact laboratory for turning random moves into winning strategies, and that’s exactly why this project matters. How do you turn random moves into a reliable, winning strategy using reinforcement learning? We’ll treat the game as a sequential decision problem: the

Why YAML Matters in dbt Building on this foundation, dbt YAML is the connective tissue that turns SQL models into an operational, testable analytics product. If your repo has many models but inconsistent metadata, you’ll struggle to trust outputs and onboard new teammates. Using dbt YAML early forces a contract-first
