## Resource

The boundaries between data engineering, MLOps, and AI engineering are dissolving as workloads shift from simple ETL to complex, real-time inference. This evolution requires moving beyond data plumbing toward managing unstructured data, vector embeddings, and high-availability AI systems.

## Highlights
- Main idea: The role of the data engineer is expanding from managing structured pipelines to orchestrating complex flows involving unstructured data and vector embeddings
- Failure mode: Relying on traditional batch-oriented reliability patterns for customer-facing AI, where downtime in vector stores directly impacts real-time user experiences
- Practical takeaway: Engineering teams must prioritize 'evaluation flows' as a fundamental testing practice to build confidence in model outputs
- Main idea: The rise of AI is forcing closer collaboration between data, ML, and application engineers, breaking down traditional hand-off silos
- Practical takeaway: Modern orchestration must handle both traditional ETL and the new, interactive requirements of agentic workflows and memory stores

## Topics

Data Engineering, AI Engineering, MLOps, Vector Databases, Unstructured Data, Data Orchestration, Data Governance, Machine Learning

## Chapters
