+___ + +# Inventory & Orders Service Example + +## Example Overview + +This example simulates an **e-commerce service** that manages inventory and orders. It demonstrates how Flamingock coordinates multiple target systems in lockstep using the **Change-as-Code** approach. + +The story begins when the **marketing team** launches a promotional campaign that requires support for **discount codes**. +To implement this feature safely, the product and engineering teams plan a sequence of deployments, each introducing incremental changes in a controlled, auditable way. + +As development progresses, the **sales team** also requests the ability to quickly search and report on orders by discount code. +This leads the engineers to add an index on the new field as part of the rollout, ensuring the system remains both functional and performant. + +### Lifecycle of the feature rollout + +1. **Initial deployment** + *Business driver:* prepare the system for discounts while keeping the feature hidden. + - Add the `discountCode` field to the `orders` collection in **MongoDB**. + - Update the `OrderCreated` schema in **Kafka** to include the same field. + - Create feature flags for discount functionality via **LaunchDarkly Management API**. + - Deploy application code that can *handle* the new field and flag, but does not yet *use* them. + - **Associated Flamingock changes:** + - [`AddDiscountCodeFieldToOrders`](#adddiscountcodefieldtoorders) + - [`UpdateOrderCreatedSchema`](#updateordercreatedschema) + - [`AddFeatureFlagDiscounts`](#addfeatureflagdiscounts) + +2. **Second deployment** + *Business driver:* ensure existing and new orders remain consistent. + - Backfill existing orders with a default `discountCode` (e.g. `"NONE"`). + - Application logic begins to populate the field for new orders, still hidden behind the flag. + - Add an index on the `discountCode` field for efficient reporting queries, requested by the sales team. + - **Associated Flamingock changes:** + - [`BackfillDiscountsForExistingOrders`](#backfilldiscountsforexistingorders) + - [`AddIndexOnDiscountCode`](#addindexondiscountcode) + +3. **Runtime activation (no deployment)** + *Business driver:* marketing activates discounts for customers. + - The feature flag is enabled at runtime using a feature-flag tool (e.g. Unleash, LaunchDarkly). + - No redeployment is required — the system is already prepared. + +4. **Final deployment** + *Business driver:* make the discounts feature permanent and clean up temporary scaffolding. + - Archive temporary feature flags via LaunchDarkly Management API using Flamingock. + - Remove the conditional `if (flag)` logic from the application code. + - The discounts feature is now permanent and the system has been fully cleaned up. + - **Associated Flamingock changes:** + - [`CleanupFeatureFlagDiscounts`](#cleanupfeatureflagdiscounts) + - [`CleanupOldSchemaVersion`](#cleanupoldschemaversion) + +### What this demonstrates + +This example showcases Flamingock’s ability to: +- Introduce, evolve, and later clean up **multiple target systems** (databases, event schemas, and configuration files). +- Support the **realistic lifecycle of a feature rollout**, spanning multiple deployments. +- Keep system evolution **controlled, auditable, and aligned with application code changes**. + +--- + +## Table of Contents + +- [Target Systems](#target-systems) +- [Complementary Stack](#complementary-stack) +- [Prerequisites](#prerequisites) +- [Dependencies](#dependencies) +- [How to Run this Example](#how-to-run-this-example) +- [Proven Functionalities](#proven-functionalities) +- [Implemented Changes](#implemented-changes) +- [Contributing](#contributing) +- [Get Involved](#get-involved) +- [License](#license) + +--- + +## Target Systems + +This example coordinates changes across three different target systems: + +1. **MongoDB** -
