Data pipelines are an integral part of modern data architectures, responsible for extracting, transforming, and loading data from various sources to a destination. The choice of data pipeline architecture depends on a variety of factors including the type of data being handled, the required throughput and latency, the need for visibility, the ability to find and debug as well as the ease of use and flexibility of the solution. Another vital aspect of data architectures is the costs associated with extracting, transforming, and storing data not to mention maintenance overhead. In this article, we will explore the different architectures that can be used for data pipelines depending on the use case, and the technological or product options available to implement each of them.
The first consideration in choosing a data pipeline architecture is the type of data being handled. Data can be broadly classified into two categories: structured and unstructured. Structured data is organized in a well-defined format, such as rows and columns in a database table or records in a CSV file. Unstructured data, on the other hand, does not have a fixed format and can include text documents, emails, audio and video files, and social media posts, among others.
Another important factor to consider is the required throughput and latency of the data pipeline. Throughput refers to the amount of data that the pipeline can process in a given time, while latency refers to the time taken to process and deliver the data from the source to the destination.
In a data pipeline, it is important to have visibility into the different stages of data processing and the ability to debug any issues that may arise. This can be achieved through monitoring and logging capabilities, as well as the ability to roll back to a previous state in case of errors.
The ease of use and flexibility of data pipeline solutions is another important factor to consider. A solution that is easy to set up and maintain will require fewer resources and allow for quicker deployment. Flexibility in terms of the ability to handle a wide range of data sources and destinations, as well as the ability to scale up or down as needed, is a crucial aspect of a data pipeline that can mold and adapt to ever-changing business requirements.
Finally, the cost and maintenance overhead of a data pipeline solution should also be taken into account. This includes the initial cost of deployment as well as any ongoing maintenance and support costs.
Based on the above considerations, there are several possible architectures for data pipelines that can be used depending on the specific use case and overall company needs.
Batch processing is a common approach for data pipelines that handle large volumes of data, where the data is processed in chunks or batches rather than in real time. This approach is suitable for scenarios where the data does not need to be processed immediately, and a certain level of latency can be tolerated.
Batch processing pipelines typically consist of the following components:
To implement a batch-processing data pipeline, the following technologies or products can be used:
Pre-knowledge required:
Stream processing is a real-time data processing approach where data is processed as it is generated, rather than in batches. This is suitable for scenarios where data needs to be processed and made available as quickly as possible, such as in applications that require real-time analytics or alerts.
Stream processing pipelines typically consist of the following components:
To implement a stream processing data pipeline, the following technologies or products can be used:
Pre-knowledge required:
In some cases, a hybrid approach that combines batch and stream processing may be more suitable. This can be useful in scenarios where some data needs to be processed in real-time, while other data can be processed in batches.
To implement a hybrid data pipeline, the following technologies or products can be used:

In conclusion, the choice of well-known data pipeline architectures depends on the specific requirements of the use case, including the type of data being handled, the required throughput and latency, the need for visibility and debugging, the ease of use and flexibility of the solution, and the cost and maintenance overhead. There are several possible architectures to choose from, including batch processing, stream processing, and hybrid approaches, each with its own set of technological or product options.
Serverless data pipelines are a relatively new approach that allows for the creation of data pipelines without the need to manage infrastructure or servers. In this approach, the underlying infrastructure is abstracted away and the data pipeline is triggered by events, such as the arrival of new data or the completion of a processing task.
Serverless data pipelines typically consist of the following components:

Pre-knowledge required:
In the field of machine learning, data pipelines are used to extract, transform, and load data for use in training and deploying machine learning models. These pipelines may have different requirements compared to traditional data pipelines, such as the need to handle large amounts of data, the need to perform complex transformations, and the need to handle data at scale.
To implement data pipelines for machine learning, the following technologies or products can be used:
Pre-knowledge required:
In real-time applications, data pipelines are used to extract, transform, and load data in real-time, with low latency. These pipelines may be used to provide real-time analytics or to power live dashboards, for example.
To implement data pipelines for real-time applications, the following technologies or products can be used:
Pre-knowledge required:
Data pipelines for big data handle extremely large volumes of data and may require distributed processing to handle the data at scale. These pipelines may be used for tasks such as data lakes or data warehouses, where data from multiple sources requires ingestion, transformation, and loading on a regular basis.

In summary, there are several possible architectures for data pipelines depending on the specific use case and requirements. These include batch processing, stream processing, hybrid approaches, serverless data pipelines, data pipelines for machine learning, data pipelines for real-time applications, and data pipelines for big data. The technological or product options available to implement each of these architectures vary and may require different levels of pre-knowledge to use effectively.
