SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designs and evaluates data-intensive system architectures by guiding trade-offs across storage engines, replication, partitioning, transactions, and consistency models.

Core Features & Use Cases

Understands data models (relational, document, graph) and their impact on scalability and integrity.
Guides selection of storage engines (LSM vs B-tree) for writes vs reads, with real-world trade-offs.
Provides decision patterns for replication topologies, partitioning strategies, and transactional guarantees, with example scenarios.

Quick Start

Analyze a hypothetical e-commerce workload and determine the optimal storage engine, replication, and partitioning strategy to balance latency, throughput, and durability.

FAQPage Schema

How do I choose between LSM and B-tree storage engines for my workload?▼

To choose between storage engines, evaluate whether your workload is write-heavy or read-heavy. LSM trees optimize high write throughput, while B-trees provide faster read performance and predictable latency for read-intensive applications.

What is the best way to partition data in a distributed system?▼

Partitioning data requires selecting a strategy like range or hash partitioning to distribute load evenly. Your partitioning strategy must align with your query patterns to prevent hotspots and ensure scalable throughput across nodes.

How does multi-region replication affect consistency models?▼

Multi-region replication introduces latency trade-offs between strong and eventual consistency. Strong consistency guarantees correct application semantics but increases write latency, while eventual consistency lowers latency but risks stale reads across regions.

When should I use document data models instead of relational models?▼

Use document data models for workloads requiring flexible schemas and localized data aggregation. Relational models are better when your application needs strict transactional guarantees and multi-object integrity across normalized tables.

How do I evaluate transactional guarantees for a distributed database?▼

Evaluating transactional guarantees involves mapping your latency targets and durability needs against isolation levels. You must determine if your application semantics require strict serializability or can tolerate relaxed isolation for higher throughput.
