Enterprises are experiencing an explosion in the generation of data across different platforms. Utilizing this data means trying to leverage ingestion methods to have this data in a unified location. Making sure the ingestion is done in a timely way ensures that data insights can be derived to drive business growth.

The data may be structured, semistructured, or unstructured since it comes from diverse sources in batches or streams. This same data is being moved to the cloud or on-premise platforms through ETL or data ingestion tools. Integrating data from both cloud and on-premise environments allows an organization to know the holistic state of its business and take action where necessary. 

This article is going to discuss real-time data ingestion, including what it is, why it’s important, and some of its benefits and limitations. Lastly, some real-time data ingestion tools will also be highlighted to show potential offerings that may fit your use case.

What is Real-Time Data Ingestion?

Data ingestion is defined as the process of aggregating data from one or many sources to be stored in a target system. The target system where the data is loaded could be a variety of types of storage. A few examples of common target systems are a database, data warehouse, data mart, or data lake. Once loaded, the data is usually used to perform ad-hoc queries, analytics, and other business operations. 

Taking data ingestion a bit further, real-time data ingestion is the ability to move data from a source to a destination as soon as it is created or updated. In a real-time ingestion setup, data is continuously integrated across various sources, usually in small sizes, in real-time. stream processing is another term used to describe this process. With stream processing, data is not grouped in any way and is handled as a continuous stream. Each piece of data emitted or produced is transferred and loaded as soon as the ingestion layer recognizes the production of new data. 

What Are The Types of Real-Time Data Ingestion?

There are two main ways of handling data ingestion, these types include batch processing and real-time data processing. With batch processing, the ingestion process collects data from one or many data sources incrementally. The batched data is then sent to a destination system or application where the data will be stored or used. With real-time data ingestion, every added or updated piece of data is individually loaded into the target system as soon as it is recognized by the ingestion layer. Streaming data is one example of a type of real-time data ingestion since it ensures the continuous flow of data from the source to the target system. 

Data Ingestion vs. ETL

As already discussed, data ingestion is a broad term encompassing many different tactics for getting data from source to target systems. Any process that involves transferring raw data from a source to a target system could be referred to as data ingestion. The source in the data ingestion process could be anything ranging from databases, spreadsheets, IoT devices, third-party systems like CRMs, or even in-house applications. Destinations, also referred to as targets, generally tend to be a data warehouse, data lake, data mart, or similar platforms.

The general priority in data ingestion is focused on moving data from one place to another as quickly and efficiently as possible. This is typically done in a standard format for use by applications for operational purposes or prepared to meet a quality level for a specific type of storage. 

Extract, Transform, and Load (ETL), compared to plain-old data ingestion, is a more specific process. ETL deals more with the preparation of data for a final storage location, like a data warehouse or data lake. It is used to retrieve and extract data, then transformed for storage where it can be used for Business Intelligence (BI), reporting, and analytics. 

The Extract sub-process denotes the collection of data, Transform handles any necessary data transformations like sorting, filtering, or combining with another source, and Loading is focused on getting the data loaded into a destination.

Technically, the ETL process can be regarded as a branch or method of data ingestion. The ETL process is a pipeline that transforms raw data and standardizes it so that it can be moved from the source to a destination. It ensures that the data types, attributes, and properties of the raw data align with the required formats of the destination before loading it into a warehouse or data store.

Finally, it can be deduced from the explanations above that ETL and real-time data ingestion are both valuable tools for transferring data from various sources to a target system. ETL is typically used for processing data for reporting and analysis, while real-time data ingestion is focused on capturing and analyzing data in real time to enable faster decision-making.

Why Do We Need Real-Time Data Ingestion?

Implementing real-time data ingestion has become a technique that can not be overlooked by businesses today. The result of real-time data ingestion provides valuable insights to drive informed and necessary actions to move the business forward. Organizations can quickly identify and act on available growth opportunities and rectify issues immediately as they present themselves. This is all possible since real-time data ingestion provides constant data feeds to power analytics solutions and other tools. Real-time ingestion tools can provide these benefits without having an impact on the source systems with reduced latency in real or near real-time. 

Traditional batch processing, usually seen in ETL and similar processes, requires data to be moved on a specific schedule. This usually plagues the data feed with delays or the possibility of delivering unwanted or obsolete data. With this approach, data may not be useful by the time it reaches its destination system. Real-time data ingestion, on the other hand, ensures the continuous flow of data in the needed time frame for immediate analysis by users and applications. It provides clear visibility, and access to current and comprehensive data so organizations can gain the maximum value from the data to make informed decisions.

Real-time data ingestion helps teams to be able to get the necessary data, from the necessary platforms to their destination platform of choice. Once implemented, this can give teams massive flexibility in how they move data around the enterprise. For business users, it means that certain use cases and insights that were unavailable without real-time data can now be unlocked.

Benefits of Real-Time Data Ingestion

To double down on the need for real-time ingestion let's dive into the array of benefits that can be associated with real-time ingestion. Below are a few highlighted benefits.

• Availability of data: Using real-time data ingestion will ensure that data is readily available for analysis and decision-making whenever you need it since it is always at your disposal as soon as it is captured or produced.
• Reduction of duplicate data: Real-time data ingestion helps in reducing the duplication of data as data is transferred immediately after there is an alteration or change. This is a benefit over data being sent in large, batched volumes where the mistake of sending data twice can occur.
• Ease of use: Most tools associated with real-time data ingestion are easy to use as they have a user-friendly interface eliminating the need for technical expertise. All you simply have to do is to select a data source and data destination.
• Reduction of load: Using real-time data can reduce the load on the source system as data will be ingested in tiny volumes instead of large batches, as seen with typical batch-ETL processes.
• Prompt decision-making: Businesses can use the analytics derived from data ingested in real-time to make valuable tactical decisions and also gain insights from the analysis to improve their applications to provide a better user experience.
• Fault-tolerant: Unlike batch processing, where you have to rerun the entire batch job if there is a failure, in real-time data ingestion, all you have to do is rerun feed from the point of failure in the data pipeline. The chances of missing data and data integrity issues are much more minimal.

Real-Time Data Ingestion Examples

There are many use cases of real-time data ingestion in the real world, below are a few that are commonly seen.

• Real-time data ingestion in monitoring systems in the hospital: Real-time data ingestion can be used in the hospital to keep track and record a patient’s vitals and alert staff in the case of an emergency. It can also be used to make predictions of a patient’s health status or condition.
• Real-time data ingestion in monitoring financial companies: Real-time data ingestion can help external data auditors to monitor transactions and identify potential issues. This can be done by spotting unusually high trading activity quickly, detecting suspicious trading activities by comparing it to previous patterns, getting an up-to-date view of all the data from a transaction, and receiving the precise timestamps and sequence of the trade.
• Customer relationship management: Real-time data can be used to improve customer relationships as the application can track a customer’s location, purchases made, and time of purchase. With this, you can offer a customer accessible locations or outlets close to them at favorable prices.
• Real-time data ingestion for analytics in the manufacturing of automotive: In the automotive industry, having real-time data is essential as this can be used to monitor a vehicle's condition in real-time, manage the manufacturing processes and quality of production, keep an inventory of available parts in the supply chain and identifying what needs to be ordered. All these scenarios lead to improvements that directly impact the customer experience.

Limitations of Real-Time Data Ingestion 

• Increased complexity: With the ever-changing dynamics of data sources and internet devices, it can be challenging to perform data ingestion. It is difficult to connect to various data sources, identify and eliminate faults, clean the data, and pick out schema inconsistency in data.
• Sluggish process: Another challenge encountered in real-time data ingestion has to do with the writing of code to ingest data and manually creating mappings for the extraction, cleaning, and loading of data in real time. The volume of the data may be enormous and diverse making it difficult to write code. Data ingestion tools play a major role in overcoming this challenge.
• Unreliable data: If your connection is not done properly, you might not be getting the generated data in real-time hence, leading to unreliable analytics. 
• High cost: Ingesting data in real-time can be difficult to implement as it requires high-performance hardware and can be quite expensive if not implemented in the efficient ways.
• Security: Securing your data is of utmost importance and you have to constantly be on your toes to fend off any cyber attacks trying to steal your sensitive data.
