Data ingestion pipelines play a critical role in the modern big data management ecosystem. They enable businesses to collect data from various sources, transform it according to their needs, and ultimately derive valuable insights and create tangible value from that information. It involves obtaining, importing, and processing data from various sources—ranging from structured databases to unstructured documents—so that it can be stored or used in a database.

In this post, we will explain data ingestion pipelines and their place within the broader data management ecosystem.

What is Data Ingestion Pipeline?

A data ingestion pipeline is an essential component of modern data architecture. It involves transferring data from its sources to a centralized location like a database or data lake, enabling efficient data management and utilization for businesses.

data ingestion pipeline

Indeed, data sources for data ingestion pipelines can encompass a wide range of inputs, including IoT devices, legacy databases, ERPs (Enterprise Resource Planning systems), and social media feeds. Data ingestion pipelines handle different types of data, including both streaming data and batched data. Streaming data is continuously collected and processed from multiple sources, such as log files, location data, stock prices, and real-time inventory updates.

A data ingestion pipeline has three main elements:

Data sources: Provide real-world information
Processing steps: Take place between data sources and destinations
Destination: Where data ends up before deeper transformations

A simple data ingestion pipeline involves taking data from a point of origin, performing basic cleaning or preprocessing, and then writing it to a destination. Data ingestion involves:

Collecting and processing data from multiple sources
Transforming data into a structured format
Ensuring data quality
Ensuring data conforms to the format and structure required by the destination application

To create a data ingestion pipeline, you can:

Identify the desired business outcome you aim to achieve.
Design the architecture of the data ingestion pipeline to align with those goals.
Develop the pipeline using appropriate tools like MarkLogic or Hadoop.
Transform the data to make it suitable for use in a specific business application.

ETL (Extract, Transform, Load) is a traditional method used for data processing, including data ingestion. It involves extracting data from various sources, transforming it to meet specific requirements or standards, and then loading it into the desired destination.

Types of Data Ingestion.

Batch processing: Suitable for non-real-time tasks that can be run during off-peak times, such as generating daily sales reports or monthly financial statements.
Real-time processing: Enables immediate analysis and action, making it ideal for time-sensitive applications like monitoring systems, real-time analytics, and IoT applications.
Micro-batching: Involves ingesting data in small, frequent batches, providing near real-time updates without the resource demands of true real-time processing. It can be a compromise for businesses needing timely data updates but lacking the resources for full-scale real-time processing.

Why Is Data Ingestion So Important?

Data ingestion pipelines enable teams to accelerate their work by providing flexibility and agility at scale. By keeping the scope of each pipeline narrow, data teams can quickly build and configure pipelines tailored to their specific needs, allowing data analysts and scientists to efficiently move data to their preferred systems for analysis.

Here’s why data ingestion matters:

Providing Flexibility: In today’s business landscape, data comes from diverse sources with unique formats. An effective data ingestion process allows businesses to gain a comprehensive view of their operations, customers, and market trends. It also adapts to changes in data sources, volume, and velocity.
Enabling Analytics: Data ingestion is the lifeblood of analytics. Without efficient data ingestion, collecting and preparing vast amounts of data for detailed analytics would be impossible. Accurate and reliable data ingestion ensures valuable insights.
Enhancing Data Quality: During ingestion, validations and checks improve data quality. Data cleansing identifies and corrects or removes corrupt, inaccurate, or irrelevant parts of the data. Transformation also plays a role in enhancing data quality.

How Does Data Ingestion Work?

Data ingestion involves extracting data from its source or original storage location and then loading it into a destination or staging area. In a simple data ingestion pipeline, light transformations like enrichment or filtering may be applied to the data before writing it to various destinations such as a data store or a message queue. For more complex transformations like joins, aggregates, and sorts for specific analytics, applications, or reporting systems, additional pipelines can be implemented.

Here’s how it works:

Source Data Collection: Data is collected from various sources such as databases, files, streaming services, applications, IoT devices, or machine logs.
Transformation (Minimal): Unlike data integration, which involves extensive transformation, data ingestion focuses on minimal transformation. It moves and replicates source data into a target landing zone (e.g., a cloud data lake) with minimal changes.
Destination Storage: The ingested data is stored in a destination such as a cloud data lake or data warehouse. Common cloud data lake targets include Amazon S3, Google Cloud Storage, Microsoft Azure Data Lake Storage, and Snowflake.
Business Intelligence and Analytics: Once in the landing zone, the data can be used for business intelligence, downstream transactions, and advanced analytics. It becomes the foundation for data science, AI, and machine learning approaches.

How is Data Ingestion different from Data Integration?

Data ingestion is primarily concerned with the movement and consolidation of data from different sources into a centralized location, while data integration focuses on combining and harmonizing data from multiple sources to create a unified and consistent view of the data.

Data ingestion involves extracting data from its sources, transforming it if necessary, and loading it into a destination for storage or further processing. On the other hand, data integration involves not only the movement of data but also the merging, cleansing, and transforming of data to ensure consistency, accuracy, and compatibility across various data sources.
