Introduction to Data Ingestion
Data Ingestion is a part of the Big Data Architectural Layer in which components are decoupled so that analytics capabilities may begin. It is all about storage and furthering its analysis, which is possible with various Tools, Design Patterns, and a few Challenges.
Ingestion mystery can be understood using the Layered Architecture of Big Data. Let us understand the Layered architecture of the pipeline. It is divided into different layers, where each layer performs a particular function.
What is the architecture of Big Data?
The Architecture of it helps design the Data Pipeline with the various requirements of either the Batch Processing System or Stream Processing System. This architecture consists of 6 layers, which ensure a secure flow of data.
- Ingestion Layer
- Collector Layer
- Processing Layer
- Storage Layer
- Query Layer
- Visualization Layer
Ingestion LayerThis layer is the first step for the data coming from variable sources to start its journey. This means the data here is prioritized and categorized, making data flow smoothly in further layers in this process flow.
Collector LayerIn this Layer, more focus is on the transportation of data from the ingestion layer to the rest of the data pipeline. It is the Layer where components are broken so that analytic capabilities may begin.
In this primary layer, the focus is to specialize in the pipeline processing system. We can say that the information we have collected in the previous layer is processed in this layer. Here we do some magic with the data to route them to a different destination and classify the data flow, and it’s the first point where the analytic may occur.

Storage LayerStorage becomes a challenge when the size of the data you are dealing with becomes large. Several possible solutions, like Data Ingestion Patterns can rescue from such problems. Finding a storage solution is very much important when the size of your data becomes large. This layer focuses on “where to store such large data efficiently.”
Query LayerThis is the layer where active analytic processing takes place. Here, the primary focus is to collect the data value to make it more helpful for the next layer.
The visualization, or presentation tier, probably the most prestigious tier, where the data pipeline users may feel the VALUE of DATA. We need something that will grab people’s attention, pull them into, make your findings well-understood.

What is Data Ingestion?
Ingestion is the process of bringing data into the Processing system. A ingestion framework is about moving data – especially the unstructured one – from where it originated into a system that can be stored and analyzed. We can also say that this is all about collecting information from multiple sources and putting it somewhere it can be accessed. This process flow begins with the Pipeline, where it obtains or imports data for immediate use. Information can be streamed in real-time or ingested in batches. When it is ingested in real-time, then it is ingested immediately as soon as it arrives. When it is ingested in batches using the Ingestion pipeline, it is ingested in some chunks at a periodic time interval.
What is Big Data Ingestion architecture?It is the first step in building a Pipeline and the Big Data platform's System's toughest task. We plan to ingest data flows from hundreds or thousands of sources into the Data Center in this layer. The Data is coming from Multiple sources at variable speed, in different formats in the Ingestion framework. The Effective Ingestion process begins by prioritizing sources, validating individual files, and routing information to the correct destination. That’s why we should properly ingest the data using the right ingestion tools for successful business decisions making in Ingestion architecture.
What are the parameters of Data Ingestion?
This process is the most complex and time-consuming part of the entire Big Data processing architecture. Consider the following parameter while creating a Ingestion pipeline -
VelocityIt deals with how data flows in different sources like machines, networks, human interaction, media sites, social media. The movement of data can be massive or continuous in ingestion.
SizeIt implies an enormous volume of workloads. Collect information from different sources that may increase timely ingestion pipeline.
Frequency (Batch, Real-Time)Information can be processed in real-time or batch, in real-time processing as data received at the same time, it further proceeds, but in batch, data is stored in batches, fixed at some time interval, and then further moved to ingestion process flow.
Format (Structured, Semi-Structured, Unstructured)Ingestion can be done in different formats. Mostly it can be the structured format, i.e., tabular one or unstructured format, i.e., images, audios, videos or semi-structured, i.e., JSON files, CSS files, etc.
What are the Ingestion tools?In the subsequent section, we will disclose some of the most common ingestion tools, and here we go:

What are the challenges of Data Ingestion?
As the number of IoT devices increases, the volume and variance of information Sources are expanding rapidly. Therefore, get an insight into our IoT Analytics Platform which is used for extracting information from the Real-Time Ingestion pipeline, and Streaming Analytics so that the destination system can be a significant challenge regarding time and resources. Some of the other problems this process faces are –When there are numerous sources in different formats. It is the biggest challenge for the business to ingest data at a reasonable speed and further process it efficiently so that it can be prioritized and improves business decisions.
- Modern Sources tools, and consuming applications evolve rapidly during Data ingestion.
- Data produced changes without notice independent of consuming application.
- Semantic Change over time as same Data Powers new cases.
- Detection and capture of changed data this task is difficult because of the semi-structured or unstructured nature of data.
- Due to the low latency needed by individual business scenarios that require this determination
- Incorrect ingestion can result in unreliable connectivity This can disrupt communication and cause information loss.

What are the best practices of Data Ingestion?
To complete the process of Ingestion, we should use the right tools and principles:
- Network Bandwidth
- Support for Unreliable Network
- Heterogeneous Technologies and Systems
- Choose Right Format
- Streaming Data
- Business Decisions
- High Accuracy
- Maintain Scalability
- Capacity and reliability
- Data volume
Network BandwidthData Pipeline must be able to compete with business traffic. Sometimes traffic increases or sometimes decreases, so Network bandwidth scalability is the biggest Pipeline challenge. Ingestion tools are necessary for bandwidth throttling and compression capabilities.
Support for unreliable NetworkIngestion Pipeline takes data with multiple structures, i.e., images, audios, videos, text files, tabular files, XML files, log files, etc. Due to the variable speed of data coming, it might travel through the unreliable network. Pipeline should be capable of supporting this also. It is one of the most important ingestion best practices.
Heterogeneous Technologies and SystemsTools for Ingestion Pipeline must use different source technologies and different operating systems.
Choose Right FormatIngestion tools must provide a serialization format. Information comes in the variable format, so converting them into a single format will provide an easier view to understand or relate the data.
Streaming DataBest practices in this process are dependent upon business necessity whether to process the data in batch or streams or real-time. Sometimes we may require both processing in the Ingestion pipeline. So, tools must be capable of supporting both.
Business DecisionsCritical Analysis is only possible when combining information from multiple sources. For making business decisions, we should have a single image of all the data coming.
ConnectionsData keeps increasing in the Ingestion framework, new information comes, and old data modified. Each new integration can take anywhere from a few days to a few months to complete.
High AccuracyThe only way to build trust with consumers is to ensure that your data is auditable. One best practice that’s easy to implement is never to discard inputs or intermediate forms when altering data in the Ingestion process flow.
LatencyThe fresher your information, the agiler your company’s decision-making can be. Extracting data from APIs and databases in real-time can be difficult. Many target information sources, including large object stores like Amazon S3 and analytics databases like Amazon Athena, Redshift, are optimized for receiving in chunks rather than a stream.
Maintain ScalabilityIn this process, best practices vary with time. We can’t say that data will come less on Monday, and the rest of the days comes a lot for processing. So, the usage of data is not uniform. We can make our pipeline so scalable that it can handle any data coming at variable speed.
- Data Quality - Assure that the consuming application works with correct, consistent, and trustworthy information to apply this data approach's best practices.
- Capacity and reliability – The system needs to scale according to input coming, and also, it should be fault-tolerant.
- Data volume – Though storing all incoming data is preferable. Some cases are in which aggregate information is backup.
