A serverless operational data lake for retail with AWS Glue, Amazon Kinesis Data Streams, Amazon DynamoDB, and Amazon QuickSight | Amazon Web Services – News Opener

Do you want to reduce stockouts at stores? Do you want to improve order delivery timelines? Do you want to provide your customers with accurate product availability, down to the millisecond? A retail operational data lake can help you transform the customer experience by providing deeper insights into a variety of operational aspects of your supply chain.

In this post, we demonstrate how to create a serverless operational data lake using AWS services, including AWS Glue, Amazon Kinesis Data Streams, Amazon DynamoDB, Amazon Athena, and Amazon QuickSight.

Retail operations is a critical functional area that gives retailers a competitive edge. An efficient retail operation can optimize the supply chain for a better customer experience and cost reduction. An optimized retail operation can reduce frequent stockouts and delayed shipments, and provide accurate inventory and order details. Today, a retailer’s channels aren’t just store and web—they include mobile apps, chatbots, connected devices, and social media channels. The data is both structured and unstructured. This coupled with multiple fulfillment options like buy online and pick up at store, ship from store, or ship from distribution centers, which increases the complexity of retail operations.

Most retailers use a centralized order management system (OMS) for managing orders, inventory, shipments, payments, and other operational aspects. These legacy OMSs are unable to scale in response to the rapid changes in retail business models. The enterprise applications that are key for efficient and smooth retail operations rely on a central OMS. Applications for ecommerce, warehouse management, call centers, and mobile all require an OMS to get order status, inventory positions of different items, shipment status, and more. Another challenge with legacy OMSs is they’re not designed to handle unstructured data like weather data and IoT data that could impact inventory and order fulfillment. A legacy OMS that can’t scale prohibits you from implementing new business models that could transform your customer experience.

A data lake is a centralized repository that allows you to store all your structured and unstructured data at any scale. An operational data lake addresses this challenge by providing easy access to structured and unstructured operational data in real time from various enterprise systems. You can store your data as is, without having to first structure the data, and run different types of analytics—from dashboards and visualizations to big data processing, real-time analytics, and machine learning (ML)—to guide better decisions. This can ease the burden on OMSs that can instead focus on order orchestration and management.

Solution overview

In this post, we create an end-to-end pipeline to ingest, store, process, analyze, and visualize operational data like orders, inventory, and shipment updates. We use the following AWS services as key components:

  • Kinesis Data Streams to ingest all operational data in real time from various systems
  • DynamoDB, Amazon Aurora, and Amazon Simple Storage Service (Amazon S3) to store the data
  • AWS Glue DataBrew to clean and transform the data
  • AWS Glue crawlers to catalog the data
  • Athena to query the processed data
  • A QuickSight dashboard that provides insights into various operational metrics

The following diagram illustrates the solution architecture.

The data pipeline consists of stages to ingest, store, process, analyze, and finally visualize the data, which we discuss in more detail in the following sections.

Data ingestion

Orders and inventory data is ingested in real time from multiple sources like web applications, mobile apps, and connected devices into Kinesis Data Streams. Kinesis Data Streams is a massively scalable and durable real-time data streaming service. Kinesis Data Streams can continuously capture gigabytes of data per second from hundreds of thousands of sources, such as web applications, database events, inventory transactions, and payment transactions. Frontend systems like ecommerce applications and mobile apps ingest the order data as soon as items are added to a cart or an order is created. The OMS ingests orders when the order status changes. OMSs, stores, and third-party suppliers ingest inventory updates into the data stream.

To simulate orders, an AWS Lambda function is triggered by a scheduled Amazon CloudWatch event every minute to ingest orders to a data stream. This function simulates the typical order management system lifecycle (order created, scheduled, released, shipped, and delivered). Similarly, a second Lambda function is triggered by a CloudWatch event to generate inventory updates. This function simulates different inventory updates such as purchase orders created from systems like the OMS or third-party suppliers. In a production environment, this data would come from frontend applications and a centralized order management system.

Data storage

There are two types of data: hot and cold data. Hot data is consumed by frontend applications like web applications, mobile apps, and connected devices. The following are some example use cases for hot data:

  • When a customer is browsing products, the real-time availability of the item must be displayed
  • Customers interacting with Alexa to know the status of the order
  • A call center agent interacting with a customer needs to know the status of the customer order or its shipment details

The systems, APIs, and devices that consume this data need the data within seconds or milliseconds of the transactions.

Cold data is used for long-term analytics like orders over a period of time, orders by channel, top 10 items by number of orders, or planned vs. available inventory by item, warehouse, or store.

For this solution, we store orders hot data in DynamoDB. DynamoDB is a fully managed NoSQL database that delivers single-digit millisecond performance at any scale. A Lambda function processes records in the Kinesis data stream and stores it in a DynamoDB table.

Inventory hot data is stored in an Amazon Aurora MySQL-Compatible Edition database. Inventory is transactional data that requires high consistency so that customers aren’t over-promised or under-promised when they place orders. Aurora MySQL is fully managed database that is up to five times faster than standard MySQL databases and three times faster than standard PostgreSQL databases. It provides the security, availability, and reliability of commercial databases at a tenth of the cost.

Amazon S3 is object storage built to store and retrieve any amount of data from anywhere. It’s a simple storage service that offers industry-leading durability, availability, performance, security, and virtually unlimited scalability at very low cost. Order and inventory cold data is stored in Amazon S3.

Amazon Kinesis Data Firehose reads the data from the Kinesis data stream and stores it in Amazon S3. Kinesis Data Firehose is the easiest way to load streaming data into data stores and analytics tools. It can capture, transform, and load streaming data into Amazon S3, Amazon Redshift, Amazon OpenSearch Service, and Splunk, enabling near-real-time analytics.

Data processing

The data processing stage involves cleaning, preparing, and transforming the data to help downstream analytics applications easily query the data. Each frontend system might have a different data format. In the data processing stage, data is cleaned and converted into a common canonical form.

For this solution, we use DataBrew to clean and convert orders into a common canonical form. DataBrew is a visual data preparation tool that makes it easy for data analysts and data scientists to prepare data with an interactive, point-and-click visual interface without writing code. DataBrew provides over 250 built-in transformations to combine, pivot, and transpose the data without writing code. The cleaning and transformation steps in DataBrew are called recipes. A scheduled DataBrew job applies the recipes to the data in an S3 bucket and stores the output in a different bucket.

AWS Glue crawlers can access data stores, extract metadata, and create table definitions in the AWS Glue Data Catalog. You can schedule a crawler to crawl the transformed data and create or update the Data Catalog. The AWS Glue Data Catalog is your persistent metadata store. It’s a managed service that lets you store, annotate, and share metadata in the AWS Cloud in the same way you would in an Apache Hive metastore. We use crawlers to populate the Data Catalog with tables.

Data analysis

We can query orders and inventory data from S3 buckets using Athena. Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. Views are created in Athena that can be consumed by business intelligence (BI) services like QuickSight.

Data visualization

We generate dashboards using QuickSight. QuickSight is a scalable, serverless, embeddable BI service powered by ML and built for the cloud. QuickSight lets you easily create and publish interactive BI dashboards that include ML-powered insights.

QuickSight also has features to forecast orders, detect anomalies in the order, and provide ML-powered insights. We can create analyses such as orders over a period of time, orders split by channel, top 10 locations for orders, or order fulfillment timelines (the time it took from order creation to order delivery).
