Data ingestion is the process of moving data from its original storage location to a data warehouse or other database for analysis. Data engineers are responsible for designing and managing data ingestion pipelines. Data can be ingested in different modes such as real-time, batch mode, etc. In this blog, we will learn the concepts about different types of data ingestion with the help of examples.
Data ingestion is the foundational process of importing, transferring, loading, and processing data from various sources into a storage medium where it can be accessed, used, and analyzed by an organization. It’s akin to the first step in a complex journey of data transformation and utilization. The data ingested can range from small quantities to vast streams of real-time data and can originate from diverse sources like databases, SaaS platforms, IoT devices, and more.
In the era of big data, the ability to efficiently and accurately ingest data is critical. It lays the groundwork for data analysis, business intelligence, and decision-making processes. Proper data ingestion ensures that data is reliable, up-to-date, and readily available for various applications, such as machine learning models, reporting tools, and analytical frameworks.
The data source can be either structured or unstructured. Structured data sources are typically found in relational databases, while unstructured data sources include text files, images, and social media data. In order to ingest data from a data source, a data ingestion tool must be used. This tool typically uses some form of Extract, Transform, and Load (ETL) process to extract the data from the source, transform it into a format that can be loaded into the target data storage system, and then load it into that system. Once the data is ingested, it can then be accessed and analyzed by various data analytics tools.
The data can come from a variety of sources, including databases, NoSQL data stores, application logs, and social media feeds. In order to ingest data efficiently, it is important to have a clear understanding of the data’s structure and how it will be used. For example, data that will be used for analytics purposes may need to be cleansed and transformed before it can be loaded into the data warehouse. Once the data has been ingested, it can be stored in its raw form or processed further for analytics. Data ingestion is a critical part of any data management strategy.
The role of data ingestion is pivotal in the larger scheme of data processing. It forms the initial phase of the data pipeline, which typically includes stages like ingestion, storage, processing, analysis, and visualization. Ingestion is about getting the data into the system; what follows is a series of transformations and analyses that turn raw data into actionable insights.
Data ingestion might sound straightforward, but it poses several challenges:
The following are few examples of data ingestion tools:
There are primarily two types of data ingestion. They are as following:
Real-time data ingestion means that data is acquired and processed as soon as it becomes available, without any delay. In real-time data ingestion, data is transferred as it is generated. This is important for applications that need to take immediate action based on new data, such as monitoring or control systems. This type of ingestion is typically used for event-based data, such as log files, financial transactions, and sensor readings. There are many different techniques for real-time data ingestion, depending on the data source. Common data sources include streams (such as sensors or social media feeds), files (such as logs or transaction records), and databases (such as customer data). The most important thing for real-time data ingestion is timely availability of data, so the technique used must be able to handle high data volumes and meet latency requirements.
Batch data ingestion is the process of taking data from a data source and importing it into a system in batches. This can be contrasted with real-time data ingestion, which involves taking data from a data source and importing it into a system as it is generated. Batch data ingestion is typically used when data sources are not able to provide data in real time, or when data needs to be processed before it can be ingested into a system. For example, if data needs to be cleansed or transformed before it can be used, batch data ingestion would be the appropriate approach. Batch data ingestion can also be used when there is a large volume of data that needs to be imported all at once, such as historical data. In general, batch data ingestion is less complex and easier to manage than real-time data ingestion, but it can take longer to import data using this approach.
Batch data ingestion is usually done on a schedule, such as once per day. Data sources can be internal or external. Internal data sources are usually databases, while external data sources can be anything from sensors to social media feeds.
Data ingestion is the process of bringing data into your system for storage or analysis. There are two main types of data ingestion: real-time or streaming, and batch. Real-time or streaming ingestion refers to data that is brought in as it is created, while batch ingestion involves gathering data all at once and loading it into the system. Both methods have their own benefits and drawbacks, so it’s important to understand which one will work best for your needs.
