What is Data Ingestion?

Data Ingestion 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.

Enterprise data can usually be stored in multiple formats and sources. For instance, sales data is stored in Salesforce.com, Relational Database Management Systems stores product information, etc. Since this data originated from various locations, it needs to be spruced and converted into a format that can be easily analyzed for decision-making with the help of an easy-to-use Data Ingestion tool like Hevo Data. Otherwise, you would be left with puzzle pieces that cannot be collated together.

What are the Types of Data Ingestion?

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 of Data Ingestion to help you get started with them. 

Batch-based Data 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.

Real-time/Streaming Data Ingestion

Data 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.

Lambda-based Data 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.

Batch vs Streaming Data Ingestion: What is the Difference?

Business constraints and requirements inform the structure of a particular project’s Data Ingestion layer. The correct ingestion model supports an optimal data strategy, and businesses typically select the model that’s apt for each data source considering the timeliness with which they’ll need analytical access to the data:

  • Real-time Processing is also known as Stream Processing does not involve the grouping of data. Data is manipulated, sourced, and loaded as soon as it’s generated or recognized by the Data Ingestion layer. This kind of ingestion is considered more expensive since it requires systems to constantly monitor sources and accept new information. However, it might be appropriate for analytics that needs continually refreshed data.
  • The most common kind of Ingestion process is Batch Processing. Here, the ingestion layer regularly collates and groups source data and moves it to the destination systems. Groups may be processed based on any logical ordering, the activation of specific conditions, or a simple schedule. When having near-real-time data isn’t important, Batch Processing is typically used because it is generally more affordable and easier to implement compared to Stream Processing.
  • It is also worth noting that a couple of streaming platforms like Apache Spark Streaming leverage Batch Processing. Here the ingested groups are simply smaller or are prepared at shorter intervals, but still not processed individually. This type of processing is called micro batching and is considered by some to be another distinct category of Data Ingestion.

Why do you need a Data Ingestion Layer?

Here are a few reasons why a Data Ingestion Layer might be integral to the smooth functioning of your Data Pipeline:

  • Uniformity: A high-quality process can easily turn different types of data into unified data that is easy to read and execute statistics and manipulations on.
  • Availability: The data can be availed by all the users with the help of a Data Ingestion layer: developers, BI analysts, sales teams, and anyone else in the company. 
  • Saves Time and Money: A Data Ingestion process saves valuable time for the engineers trying to collate data they need and develop it efficiently instead.

What are the Benefits/Advantages of Data Ingestion?

Here are a few key advantages of using Data Ingestion for your business use case:

  • Data Ingestion 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 Data Ingestion services.
  • Data Ingestion also enables a company to make better decisions, create superior products, and deliver improved customer service.
  • Data Ingestion 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 use Data Ingestion to ensure that their software tools and apps move data quickly and provide users with a superior experience. 

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 Ingestion 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 resemblance to ETL tools in terms of functionality, but there are a few pivotal differences that set them apart. Data Ingestion is primarily concerned with extracting data from the source and loading it into the target site. ETL, on the other hand, is a type of Data Ingestion process that consists of not only the extraction and transfer of data but also the transformation of that data before it gets delivered to the target.

What are the Challenges of Data Ingestion?

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

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

Best Practices for Data Ingestion: 5 Must-know Strategies

Here are the best practices for Data Ingestion to ensure your pipeline runs smoothly:

  • Automate the Process: As the data continues to grow in both 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. For instance, if you wish to extract data from a delimited file stored in a folder, transfer and cleanse it into the SQL Server. This process needs to be repeated every time a new file is dropped in the folder. By leveraging a Data Ingestion tool you can automate the process by using event-based triggers that can help optimize the entire ingestion cycle.
  • Anticipate Difficulties: The prerequisite of analyzing data is transforming it into a useable 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. The first step of developing a data strategy would be to outline the challenges associated with your specific use case difficulties and take them into stride. For example, identify the source systems at your disposal and make sure you know how to extract data from these sources. You can also acquire external expertise or leverage a code-free Data Integration tool to help with the process.
  • Enable Self-service Data Ingestion: 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 Data Ingestion can empower business users to handle the process with minimal intervention from the IT team.
  • Choose the Right Data Format: Data Ingestion tools need to provide a suitable data serialization format. Generally, data comes in the variable format, so converting them into a single format will offer an easier 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 quite difficult. Various target data sources including large object-stores like Amazon S3 and analytics databases like Amazon Athena Redshift can be optimized for receiving data in chunks as opposed to a stream. 

Key FAQs

What are the parameters involved in Data Ingestion?

The key parameters involved in Data Ingestion are as follows:

  • Data Size: It implies an enormous amount of data. This parameter can be used to collect information from different sources that might increase timely within the Data Ingestion pipeline.
  • Data Velocity: Data Velocity deals with the flow of data in different sources like networks, machines, media sites, human interaction, and social media. The movement of data can either be continuous or massive in Data Ingestion. 
  • Data Frequency: You can process the information in batch or real-time. In real-time processing, the data is received at the same time as it moves, but in Batch Processing, data is stored in batches, fixed at a particular time interval, and then further moved to the Data Ingestion process flow.
  • Data Format: Data Ingestion can be carried out in various formats. Mostly it can be the structured format, i.e., structured or tabular format, i.e., audios, images, videos, or semi-structured, i.e., CSS files, JSON files, etc.  

What is the difference between Data Ingestion and Data Integration?

Data 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 a schema to transformation to destination.

With Data Ingestion, on the other hand, a few light transformations can be made, such as masking Personally Identifiable Information (PII), but most of the work depends on the end-use and takes place after landing the data.

What is the architectural pattern of Big Data?

The architecture of Big Data allows you to design the Data Pipeline with various requirements of either the Batch Processing System or the Stream Processing System. This architecture consists of 6 key layers, which ensures a secure flow of data.

  • Data Ingestion Layer
  • Data Collector Layer
  • Data Processing Layer
  • Data Storage Layer
  • Data Query Layer
  • Data Visualization Layer

What is Big Data Ingestion Architecture?

Big Data Ingestion architecture is the first step in developing a Data Pipeline and the Big Data platform’s system’s toughest task. The primary aim of leveraging this layer is to ingest data flows from hundreds of thousands of sources into the Data Center within this layer. The data comes from various disparate sources at variable speeds, in different formats within the Data Ingestion framework. The effective Data Ingestion process begins by prioritizing data sources, routing data items to the correct destination, and validating individual files.
