edwh plugin for quick database snapshot creation and recovery

EDWH Development Database (devdb) Plugin

Overview

The EDWH Development Database Plugin provides a comprehensive set of tools for managing snapshots of the development database. This plugin allows developers to create, push, pop, recover, and list database snapshots efficiently.

Features

• Snapshot Management: Create and manage snapshots of the development database.
• Selective Exclusion: Optionally exclude specific tables during snapshot creation.
• Remote Operations: Push and pop snapshots to/from a remote server.
• Database Recovery: Recover the database from previously created snapshots.
• Environment Setup: Easy setup of environment variables for PostgreSQL connections.

Requirements

• Python 3.12+
• Docker Compose
• PostgreSQL
• EDWH environment variables configured (usually via edwh setup)

Installation

Development Installation

To install the plugin in development mode, run:

uv pip install -e .[dev]

Production Installation

For production use, you can install the plugin using:

uvenv install edwh[devdb]

Alternatively, you can add the plugin directly with:

edwh plugin.add devdb

Usage

Environment Variables

Ensure the following environment variables are set:

• POSTGRES_USERNAME: Username for PostgreSQL (default: postgres)
• POSTGRES_PASSWORD: Password for PostgreSQL (default: password)
• PGPOOL_PORT: Port for pgpool (default: 5432)
• POSTGRES_DATABASE: Name of the PostgreSQL database (default: backend)

Then you can run edwh setup and the other required variables can be infered.

Commands

Create a Snapshot

To create a snapshot of the development database:

ew devdb.snapshot

You can exclude specific tables using optional parameters:

ew devdb.snapshot --without_api_activity False --without_applog False

List Snapshots

To list all snapshots in reverse chronological order:

ew devdb.list

Rename a Snapshot

To rename the most recent snapshot:

ew devdb.rename <new_name>

Push a Snapshot

To push the local snapshot to a remote server:

ew devdb.push

Pop a Snapshot

To download and prepare a snapshot from a given URL:

ew devdb.pop <url>

Recover a Snapshot

To recover the database from a snapshot:

ew devdb.recover

This assumes an empty database. An easier alternative is:

Reset the Database

To reset your database to the latest state:

ew devdb.reset

Notes

• Be cautious when using the reset command as it will clear your PostgreSQL database and remove all existing data.
