How Big Data is helping Flipkart to achieve the Milestone?

Flipkart the World’s number one e-commerce platform is using analytics and algorithms to get better insights into its business during any type of sale or festival season. This article will explain you how the Flipkart is leveraging Big Data Platform for processing big data in streams and batches. This service-oriented architecture empowers user experience, optimizes logistics and improves product listings. It will give you an insight into how this ingenious big data platform is able to process such large amounts of data. Before starting, I recommend you to check this Big Data guide to better understand its core concepts.

Big Data at Flipkart

Flipkart Data Platform is a service-oriented architecture that is capable of computing batch data as well as streaming data. This platform comprises of various micro-services that promote user experience through efficient product listings, optimization of prices, maintaining various types of data domains – Redis, HBase, SQL, etc. This FDP is capable of storing 35 PetaBytes of data and is capable of managing 800+ Hadoop nodes on the server. This is just a brief of how Big Data is helping Flipkart. Below I am sharing a detailed explanation of Flipkart data platform architecture that will help you to understand the process better.

The Architecture of Flipkart Data Platform

To know how Flipkart is using Big Data, you need to understand the flow of data or Flipkart’s data platform architecture which is explained through the below flow chart-

How Big Data is helping Flipkart?

Let’s take a tour to the complete process of how Flipkart works on Big Data. Starting with the FDP ingestion system –

1. FPD Ingestion System

A Big Data Ingestion System is the first place where all the variables start their journey into the data system. It is a process that involves the import and storage of data in a database. This data can either be taken in the form of batches or real-time streams. Simply speaking, batch consists of a collection of data points that are grouped in a specific time interval. On the contrary, streaming data has to deal with a continuous flow of data. Batch Data has greater latency than streaming data which is less than sub-seconds. There are three ways in which ingestion can be performed –

  • Specter – This is a Java library that is used for sending the draft to Kafka.
  • Dart Service – This is a REST service which allows the payload to be sent over HTTP.
  • File Ingestor – With this, we can make use of the CLI tool to dump data into the HDFS.

Then, the user creates a schema for which the corresponding Kafka topic is created. Using Specter, data is then ingested into the FDP. The payload in the HDFS file is stored in the form of HIVE tables.

2. Batch Compute

This part of the big data ecosystem is used for computing and processing data that is present in batches. Batch Compute is an efficient method for processing large scale data that is present in the form of transactions that are collected over a period of time. These batches can be computed at the end of the day when the data is collected in large volumes, only to be processed once. This is the time you need to explore Big Data as much as possible. Here is the free Big Data tutorials series which will help you to master the technology.

3. Streaming Platform

The streaming platforms process the data that is generated in sub-seconds. Apache Flink is one of the most popular real-time streaming platforms that are used to produce fast-paced analytical results. It provides a distributed, fault-tolerant and scalable data streaming capabilities that can be used by the industries to process a million transactions at one time without any latency.

4. Messaging Queue

A Messaging Queue acts like a buffer or a temporary storage system for messages when the destination is busy or not connected. The message can be in the form of a plain message, a byte array consisting of headers or a prompt that commands the messaging queue to process a task. There are two components in the Messaging Queue Architecture – Producer and Consumer. A Producer generates the messages and delivers them to the messaging queue. A Consumer is the end destination of the message where the message is processed.

The most popular tool used in Messaging Queues is Kafka. Apache Kafka is an open-source stream-processing software system that is heavily inspired by the transaction logs. Thousands of companies around the world make use of Kafka as their primary platform for buffering messages. Its scalability, zero fault tolerance, reliability, and durability make it an ideal choice for industry professionals.

Wait! Have you checked the latest Kafka tutorials

5. Real-time Serving

After the messages are retrieved from the Messaging Queue, the real-time serving system acts as a consumer for the messaging queue. With the help of this real-time serving platform, users can gather real-time insights from the data platform. Furthermore, with the help of real-time serving, the users can access the data through dynamic pipelines.

6. Data Lake

The core component of this architecture is the data storage platform. This is a Hadoop platform that stores raw data, journaled data as well as derived data. Using this, the data is stored in the form of a backup, archive that can be retrieved or purged according to the requirements. The raw data is mostly used by the data scientists who use the insights from the original data to make decisions and develop data products. The data is present in the form of batches or real-time streams. The real-time data is in the form of click streams, summarized reports of user data, product insights, reviews, etc.

From the data lake, data is transferred to three main routes –

a. Reports

The reports are generally produced from the batch data. These reports allow a comprehensive insight into website logs, daily website readings and other forms of reports. With the help of these reports, companies like Flipkart are able to quantify the market needs as well as

b. Ad hoc Query

Ad hoc Query is designed for some specific purpose or use. The Adhoc Queries that are generated from the data-lake are handled by the data analysts. These data analysts make use of various business intelligence tools to discover meaning from the data.

c. Batch Export

This part of the data platform takes the data from data-lake and exports it in various formats to the further processing platforms. The data is present in huge bulks that are exported.

7. Knowledge Graphs

Knowledge graphs represent an inter-linked network of real-world entities or objects through which we can extract information to process it in an efficient manner. This knowledge graph takes input from the meta-data. This metadata is beneficial for understanding the underlying semantics which is used for deriving newer facts. The knowledge graph also makes use of various machine learning tools and libraries to gain insights and understand the relationships between the objects. One of the most popular tools that are used for building graph is Apache Spark’s GraphX library.
