DDIA Systems

Skill Verified Active

Design data systems by understanding storage engines, replication, partitioning, transactions, and consistency models. Use when the user mentions "database choice", "replication lag", "partitioning strategy", "consistency vs availability", "stream processing", "ACID transactions", "eventual consistency", or "LSM tree vs B-tree". Also trigger when choosing between SQL and NoSQL, designing data pipelines, or debugging distributed system consistency issues. Covers data models, batch/stream processing, and distributed consensus. For system design, see system-design. For resilience, see release-it.

Purpose

To provide principled guidance and a structured framework for designing reliable, scalable, and maintainable data systems by understanding core concepts and trade-offs.

Features

  • Expert guidance on data models and query languages
  • Explanation of storage engines (LSM vs B-trees)
  • In-depth coverage of replication strategies and consistency models
  • Principles for partitioning and scaling data
  • Guidance on transactions, batch, and stream processing

Use Cases

  • Choosing the right database for a specific problem
  • Designing schemas and data models that scale
  • Architecting distributed systems with fault tolerance
  • Debugging consistency issues in data pipelines
  • Understanding trade-offs between consistency, availability, and latency

Non-Goals

  • Implementing specific database technologies
  • Providing operational runbooks for databases
  • Writing code for specific data pipelines

Workflow

  1. Understand core data system principles (models, storage, replication, partitioning, transactions, processing, reliability)
  2. Apply principles to design new systems or evaluate existing ones
  3. Use provided diagnostic questions and common mistake analyses
  4. Consult reference files for deeper dives into specific topics

System Design

99

Design scalable distributed systems using structured approaches for load balancing, caching, database scaling, and message queues. Use when the user mentions "system design", "scale this", "high availability", "rate limiter", "design a URL shortener", "system design interview", "capacity planning", or "distributed architecture". Also trigger when estimating infrastructure requirements, choosing between microservices and monoliths, or designing for millions of concurrent users. Covers common system designs and back-of-the-envelope estimation. For data fundamentals, see ddia-systems. For resilience, see release-it.
