cell-architecture

What problem does it solve?

Provides a concise reference and migration guide for Sentry's cell-based architecture, helping engineers understand how cells and localities partition deployments, route requests, and migrate data safely across boundaries.

Core Features & Use Cases

• Architecture Reference: Explains the concepts of cells and localities, and how routing works across cross-cell boundaries.
• Migration Guidance: Documents two-phase deployment patterns, edge cases, and known issues to minimize risk during transformation.
• Cross-Cell Data Understanding: Describes data access patterns, mapping services, and how to reason about multi-cell queries.
