PostgREST vs Sqitch: What are the differences?

Introduction

PostgREST and Sqitch are two different tools used in database management. While PostgREST is an automatic API for PostgreSQL databases, Sqitch is a database change management tool. Despite their roles in database management, there are key differences that set them apart from each other. In this article, we will explore the top 6 differences between PostgREST and Sqitch.

1. Architecture: PostgREST is designed as a standalone server that sits between the client and the PostgreSQL database, providing a RESTful API. On the other hand, Sqitch is a command-line tool that focuses on managing and deploying database changes from project source files.

2. Functionality: PostgREST primarily provides an automatic and instant API for PostgreSQL databases, allowing clients to access database resources through RESTful endpoints. Sqitch, however, focuses on tracking and managing database schema changes, providing a version control system for migrations.

3. API Interface: PostgREST generates a REST API automatically from the PostgreSQL schema, providing a standardized interface for clients to interact with the database. Sqitch, in contrast, does not offer an API interface by default. It focuses on tracking and managing database changes rather than exposing them through specific endpoints.

4. Deployment Process: PostgREST deployment typically involves installing and configuring the PostgREST server alongside the PostgreSQL database. It requires no additional schema management or migrations. Sqitch, on the other hand, requires manual deployment of database changes using the Sqitch command-line tool, which tracks migrations and applies them to the corresponding databases.

5. Database Change Management: PostgREST does not provide specific functionalities for tracking and managing database schema changes. It is primarily used for API generation. Sqitch, on the other hand, excels at managing database changes, providing a comprehensive system for version control, deployment, and rollback of migrations.

6. Development Process Integration: PostgREST can be seamlessly integrated into the development process, automatically generating APIs based on the PostgreSQL schema. Sqitch can also be integrated to track and manage database changes, providing a streamlined approach to development and deployment.

In summary, PostgREST and Sqitch differ in their architectural design, functionality, API interface, deployment process, database change management capabilities, and integration into the development process. PostgREST focuses on generating automatic APIs for PostgreSQL databases, while Sqitch excels at managing database schema changes through version control and deployment.
