What is Data Ingestion? A Complete Guide

Organizations depend heavily on data for predicting trends, planning for future requirements, making business decisions, understanding consumers, and predicting the market. However, to execute these tasks, it is necessary to get fast access to enterprise data in a single location. This is where the ingesting of data comes in handy. It refers to the extraction of information from disparate sources so that you can uncover actionable insights hidden within your data and use them for your unique business case to propel growth.

This article talks about the different salient aspects of data ingestion in detail, such as its types, benefits, importance, working, challenges, key tools to look out for, and so much more.

What is Data Ingestion?

It is defined as the process of absorbing data from a vast multitude of sources and transferring it to a target site where it can be analyzed and deposited. Generally speaking, the destinations can either be a document store, database, Data Warehouse, Data Mart, etc. You can also choose from different source options such as Web Data Extraction, spreadsheets, Web Scraping, SaaS data, and in-house apps.

Key Features

Here are its key features:

• Sources of data: Data can be obtained from a wide variety of sources such as databases, files, applications, IoT devices, or machine logs.
• Destination: The data is usually transferred to a database, data warehouse, or data lake.
• Data preparation: Data is usually raw and in various formats. Hence, it needs sanitizing and transforming into a uniform format. This is done by an ETL process.
• Data integrity: Integrity and quality of the data must be maintained along with the process.

Integrating data ingestion tools into your data integration strategy ensures all data sources are accessible and ready for analysis.

Data Ingestion Architecture & Patterns

You can use a framework to effectively and efficiently ingest data from your various sources into a target system. It is a set of processes that allows you to consistently and reliably get data into the target system, regardless of the complexity or volume of the data sources. A basic, well-defined data ingestion architecture includes the following data layers:

• Ingestion Layer: Responsible for extracting data from multiple sources into your data pipeline.
• Data Collection Layer: This handles the collection and storage of data in a temporary staging area.
• Data Processing Layer: Consisting of functions such as data transformation logic and quality checks, this layer prepares the data for storage.
• Data Storage Layer: Takes care of storing data in repositories such as databases, data warehouses, and data lakes.    
• Data Query Layer: Offering SQL Interfaces and BI tools, this layer provides you access to the stored data for querying and analysis.
• Data Visualisation: This layer allows you to make reports and dashboards to present the data in a meaningful and understandable way to users.

Parameters of Data Ingestion

To effectively implement a data pipeline, you have to fine-tune your architecture. You can do that by going through the following parameters for ingesting of data:

• Data Volume: The amount of data being ingested. This could be measured in terms of the size of the data, the number of records or rows, or the rate at which data is ingested.
• Data Frequency: It is the frequency at which you need fresh or updated data. You can either do the near-real-time replication or go for the batch mode processing, where data is first stored in batches and then moved into the pipelines. 
• Data Velocity: It refers to the rate at which data is generated, transmitted, and processed. 
• Data Format: The format in which the data is stored or transmitted. This could be a structured format, such as CSV or JSON, or an unstructured format, such as text or binary data. 

What are the Data Ingestion Types?

It can be executed in various ways, such as in real-time, batches, or a combination of both (also known as lambda architecture) based on the unique business requirements of the user. This section will be taking a closer look at the different types to help you get started with them. 

1. Batch-based Ingestion

When this process takes place in batches, the data is moved at recurrently scheduled intervals. This approach comes in handy when tackling repeatable processes. For example, reports that need to be generated daily.

2. Real-time/Streaming Ingestion

Ingestion executed in real-time is also referred to as Streaming data among the developers. Real-time ingestion plays a pivotal role when the data collected is very time-sensitive. Data is processed, extracted, and stored as soon as it is generated for real-time decision-making. For instance, data acquired from a power grid needs to be continuously monitored to ensure a steady flow of power.

3. Lambda-based Ingestion Architecture

The Lambda architecture balances the advantage of the aforementioned methods by leveraging Batch Processing to offer broad views of batch data. On top of this, Lambda architecture uses real-time processing to offer views of time-sensitive information as well.

What are the Benefits of Data Ingestion?

Here are a few key advantages of ingesting data for your business use case:

• It helps a business gain a better understanding of its audience’s needs and behavior to stay competitive which is why ample research needs to be done when looking up companies that offer ingestion services.
• It also enables a company to make better decisions, create superior products, and deliver improved customer service.
• It automates some of the tasks that previously had to be manually executed by engineers, whose time can now be dedicated to other more pressing tasks.
• Engineers can also ensure that their software tools and apps move data quickly and provide users with a superior experience.

Real-World Industry & Architectural Use Cases

• Big Data Analytics: Ingesting large volumes of data from multiple sources is a common requirement in big data analytics, where data is processed using distributed systems such as Hadoop or Spark.
• Internet of Things (IoT): It is often used in IoT systems to collect and process data from a large number of connected devices.
• E-commerce: E-commerce companies may ingest data to import data from various sources, including website analytics, customer transactions, and product catalogs.
• Fraud detection: It is often used in fraud detection systems to import and process data from multiple sources, such as transactions, customer behavior, and third-party data feeds.
• Personalization: It can be used to import data from various sources, such as website analytics, customer interactions, and social media data, to provide personalized recommendations or experiences to users.
• Supply Chain Management: It is often used in supply chain management to import and process data from various sources, such as supplier data, inventory data, and logistics data.

Data Ingestion vs Data Integration

Aspect	Data Ingestion	Data Integration
Definition	The process of collecting and importing data from various sources into a storage system.	The process of combining data from different sources to provide a unified view.
Focus	Emphasizes the initial collection and loading of data.	Focuses on ensuring that disparate data sources work together seamlessly.
Methods Used	Can include batch ingestion, real-time ingestion, and micro-batching.	Uses various methods, including data federation and virtualization.
Use Cases	Useful for scenarios requiring immediate access to data or large data loads at specific intervals.	Essential for creating a comprehensive view of data across multiple sources for analytics.
Tools	Hevo, Apache Kafka, AWS Kinesis, Fivetran, Apache Nifi.	Hevo, Informatica, Talend, Microsoft Azure Data Factory.

Ingestion originated as a small part of Data Integration, a more complex process needed to make data consumable in new systems before loading it. Data Integration usually needs advanced specifications from source to schema to transformation to destination.

When comparing ingestion vs data integration, ingestion allows only a few light transformations, such as masking Personally Identifiable Information (PII), but most of the work depends on the end-use and takes place after landing the data.

Challenges Companies Face while Ingesting Data

Maintaining and setting up a pipeline might be much simpler than before, but it still comes with its fair share of data ingestion challenges:

• Scalability: When dealing with data ingestion on a large scale, it can be a little difficult to ensure data consistency and ensure that the data conforms to the structure and format that the destination application needs. Large-scale ingestion could also suffer from performance challenges.
• Data Quality: Maintaining data completeness and data quality during ingestion is a significant challenge. Checking data quality must be part of the ingestion process to allow useful and accurate analytics.
• Risk to Data Security: Security is one of the biggest challenges when moving data from one point to another. Data can often be staged in various phases throughout the ingestion process. This can make it challenging to fulfill compliance standards during the ingestion process.
• Unreliability: Incorrectly ingesting of data might lead to unreliable connectivity. This can end up disrupting communication and cause loss of data.
• Data Integration: It might be a little tricky to integrate data from various third-party sources into the same Data Pipeline, so you need a comprehensive Data Ingestion tool that allows you to do just that.

Best Practices for Ingesting Data: 5 Must-know Strategies

Here are the best practices for ingesting data to ensure your pipeline runs smoothly:

• Automate the Process: As the data grows in complexity and volume, you can no longer depend on manual techniques to curate such a huge amount of data. Therefore, you can consider automating the entire process to increase productivity, save time, and reduce manual efforts.
• Anticipate Difficulties: The prerequisite of analyzing data is transforming it into a usable form. As the data volume increases, this part of their job becomes more difficult. Therefore, anticipating difficulties and planning accordingly is essential to its successful completion.
• Enable Self-service: Your business might require various new data sources to be ingested weekly. And if your company functions on a centralized level, it might run into trouble in performing every request. Therefore, automating the process or opting for self-service can empower business users to handle the process with minimal intervention from the IT team.
• Choose the Right Data Format: Tools for ingestion of data need to provide a suitable data serialization format. Generally, data comes in a variable format, so converting them into a single format will offer a more straightforward view to relate or understand the data.
• Latency: Fresh data guarantees more agile business decision-making. Extracting data from databases and APIs in real-time can be pretty tricky. Various target data sources, including large object stores like Amazon S3 and analytics databases like Amazon Athena Redshift, can be optimized to receive data in chunks instead of as a stream.

Batch vs Streaming Data Ingestion: What is the Difference?

Feature	Batch	Stream
Latency	High (processed in bulk after collection)	Low (processed in real-time as it arrives)
Data Volume	Large volumes of data processed at once	Continuous small amounts of data
Processing Frequency	Scheduled Intervals	Continuously, the data is being ingested.
Resource Utilization	Optimized for off-peak hours.	Requires continuous resource allocation.
Scalability	Efficient for large datasets but less flexible	Highly scalable for handling dynamic loads

How Does Data Ingestion Work?

Data Ingestion extracts data from the source where it was generated or originally stored and loads data into a staging area or destination. A simple data pipeline might apply one or more light transformations that would filter or enrich the data before writing to a set of destinations, a message queue, or a data store. More complex transformations such as aggregates, joins, and sorts for specific applications, analytics, and reporting systems can be performed with supplementary pipelines.

Data Ingestion vs ETL: What Sets them Apart?

Data Ingestion tools might bear a resemblance to ETL tools in terms of functionality, but there are a few pivotal differences that set them apart. Ingestion is primarily concerned with extracting and loading data from the source into the target site. ETL, on the other hand, is a type of ingestion process that consists of the extraction and transfer of data and the transformation of that data before it gets delivered to the target.
