SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides expert knowledge for contributing to Litestream, a standalone disaster recovery tool for SQLite. It consolidates architectural understanding, code patterns, critical rules, and debugging procedures for WAL monitoring, LTX replication format, storage backend implementation, multi-level compaction, and SQLite page management. It is intended for developers working with the Litestream source, writing storage backends, debugging replication issues, implementing compaction logic, or handling SQLite WAL operations.

Core Features & Use Cases

  • Architectural guidance for Litestream components
  • Best practices for implementing replication, WAL monitoring, and compaction
  • Debugging procedures and error-handling guidance for restoration and point-in-time (PIT) restores
  • Use Case: When adding or reviewing Litestream's storage backends, use this Skill to align with project architecture and patterns

Quick Start

  • Clone the Litestream repository and read this Skill's frontmatter to confirm scope and license
  • Review the architecture and reference guides under references/ARCHITECTURE.md and references/REPLICA_CLIENT_GUIDE.md to orient implementation
  • Apply the guidance when contributing to Litestream code, tests, or storage backends

FAQPage Schema
How does Litestream handle SQLite disaster recovery using WAL monitoring?

SQLite disaster recovery with Litestream works by continuously monitoring the Write-Ahead Log (WAL) and replicating page changes to a remote storage backend, ensuring data can be restored to a specific point in time.

How do I implement a custom storage backend for Litestream replication?

Implementing a Litestream storage backend requires following the project's architectural patterns and replica client guide to properly manage the LTX replication format and integrate with the existing system.

What is the LTX replication format in SQLite disaster recovery?

The LTX replication format is the transactional file structure used by Litestream to encapsulate SQLite WAL page changes, enabling efficient multi-level compaction and point-in-time restoration.

Why is my Litestream point-in-time restore failing or missing data?

Litestream point-in-time restore failures often stem from WAL monitoring interruptions or gaps in the LTX replication sequence; use the project's specific debugging procedures to inspect SQLite page management and resolve errors.

Can I use Litestream for multi-level compaction on large SQLite databases?

Litestream supports multi-level compaction to manage storage efficiently for large SQLite databases, consolidating transactional LTX files to reduce the overhead of continuous WAL replication.

Do I need to understand SQLite page management to contribute to Litestream?

Understanding SQLite page management is essential for contributing to Litestream, as the tool directly reads page-level changes from the WAL to generate LTX replication files and execute disaster recovery restores.
