What You Should Know on Data Pipeline Architecture and Tools – Spiceworks News and Insights

A data pipeline moves one or more datasets from their source to the destination via connected data processing elements.

A data pipeline is defined as the process of moving one or more datasets from their source to the destination location through multiple, connected data processing elements – where one element’s results act as the input of the next. This article details its meaning, architecture, and the various tools one can use.

A data pipeline is a system for ingesting raw information from various sources and then transferring it to analytics-ready file storage, like a data lake or warehouse. Before data is typically stored in a database, it undergoes data processing.
This includes data transformations like screening, masking, and groupings, which ensure the integration and standardization of data appropriately. This is especially crucial when the dataset is intended for a relational database. This database has a predetermined structure; therefore, updating current information with new data needs alignment, i.e., linking data rows and types.
What are the underlying workings of a data pipeline?
As their name indicates, data pipelines serve as conduits for data science initiatives and business intelligence dashboards. Data may be obtained from several sources, including APIs, structured query language (SQL), NoSQL databases, files, etc., but it is often not immediately usable. Data preparation responsibilities are often assigned to data analysts or database administrators, who organize the data to fulfill the requirements of the enterprise application.
A mix of exploratory investigation and business needs often determines the type of data processing needed by a workflow. After the content has been appropriately filtered, merged, and summarized, it may be stored and made available. Well-organized data pipelines form the foundation for many data efforts, such as exploratory data analysis, visualization, and machine learning tasks.
The data pipeline encompasses the following operations:
Any functional or organizational activity that involves frequent automated aggregation, cleaning, transformation, and dissemination of data to subsequent data consumers requires a data pipeline. Typical data users include:
Numerous data pipelines also transfer data among advanced data refinement and conversion units, wherein neural network models and ML algorithms may construct more sophisticated data conversions and enrichments. This comprises classification, regression analysis, grouping, and developing sophisticated indices and propensity ratings.

ETL is a particular sort of data pipeline. ETL stands for extract, transform, and load. It is the procedure of transferring information from one source, like an app, to a target, which is often a data warehouse. “Extract” refers to retrieving data from a source; “Transform” refers to changing the data to load it into the destination, and “Load” refers to entering the information within the destination.
Some terminology, including data and ETL pipelines, may be used interchangeably in a discussion. However, you should consider ETL pipelines a subset of data pipelines. Three distinguishing characteristics define the two kinds of pipelines.
ETL pipelines adhere to a specified order. As the acronym suggests, they extract and convert data before loading and storing it in a database. Not all data pipelines must adhere to this schedule. Cloud-native solutions have increased the use of ELT pipelines. With this pipeline, data ingestion happens first, but transformations are executed after the material is stored within the cloud database system.
ETL pipelines often indicate the usage of batch processing; however, as stated before, the extent of data pipelines is larger. Moreover, they may include stream processing.
Lastly, while it is improbable, data pipelines generally are not required to perform data transformations like ETL pipelines. Rarely do data pipelines exist that do not use modifications to enhance data analysis.

A data pipeline is designed to automate and expand routine data gathering, transformation, transfer, and integration processes. A correctly established data pipeline approach may expedite and automate the collection, cleaning, converting, enriching, and transfer of information to subsequent systems and applications.
As the volume, diversity, and frequency of information continue to increase, the requirement for data pipelines that can expand linearly in hybrid and cloud settings is becoming more crucial to the company’s daily operations. Data management has become a greater issue as the volume of big data keeps increasing. Even though data pipelines serve various purposes, they have three primary commercial uses:
Imagine you operate an e-commerce site and intend to use BI tech like Tableau to examine purchase history. One must construct a data pipeline to transfer all transaction information from the source repository if one uses a data warehouse. Then, using Tableau, you might construct a data pipeline built from the database system to generate cubed or aggregated components to make the information simpler to study.
Alternatively, you may have a pipeline running across the transaction data source and your cloud data lake if you utilize a data lake. Then, BI tools such as Tableau can immediately search the material in the cloud data center
In the real world, data pipelines are analogous to plumbing systems. Both are conduits for meeting basic requirements (to shift information or “water,” respectively). Both may break and require maintenance.
In several organizations, data engineering teams will build and look after data pipelines. This should be automated as much as feasible to bring down the amount of human oversight necessary. However, even with automation, enterprises must consider the following factors:

Data pipelines might be designed in many ways. Batch-based data pipelines are the first. An application, like a point-of-sale system, may create a significant quantity of data points that need to be sent to a database system and an analytics database.
Streaming data pipelines are a second sort of design. A streaming data pipeline would process data from the point-of-sale system as it is produced. The stream processing engine might provide pipeline outputs to data storage, marketing applications, and customer relationship management systems, among many other apps, as well as the point of sale systems.
Additionally, one may use the Lambda architecture, which mixes batch and streaming pipelines. Lambda architecture is used in big data contexts because it allows developers to simultaneously accommodate real-time streaming use case scenarios and historical batch analysis. A fundamental component of this design is that it promotes data storage in a raw format such that you may continuously operate new data pipelines to remedy any code problems in previous pipelines or build additional data destinations that allow new forms of queries.
Finally, you have the event-driven data pipeline architecture. Occurrence or event-driven processing is advantageous when a preset event on the source system prompts immediate response (like anti-lock systems, airbags, fraud analysis, or fire hazard awareness). When the planned event happens, the data pipeline harvests and transmits the necessary data to a subsequent procedure.
Across all of these architectures, a data pipeline has the following components:
Origin is the data pipeline’s point of data input. A company’s monitoring and analytical data ecosystem may include sources of data (transaction processing software, connected devices, social networks, APIs, and any accessible dataset) and storage systems (storage server, data lake, or data lakehouse).
A destination is the last location toward which data is transmitted. Depending on the use case, one may supply data to fuel data visualization and analytical tools or relocate to storage such as data lakes or data warehouses. We will return to the sorts of storage shortly.
This is the transportation of data from its original source to its ultimate destination, including the conversions and data storage it encounters along the route.
Storage refers to procedures in which data is maintained at various points along the pipeline. The options for data storage rely on a variety of parameters, such as the amount of data, the regularity, and quantity of queries to a storage system, the purposes of the data, etc.
Processing involves acquiring information from various sources, storing it, changing it, and sending it to a target recipient. Although data processing is connected to dataflows, it involves implementing this movement. One may extract data from source systems, transfer it from one database to another (database replication), or stream it. We only described three alternatives – but there are more.
A data pipeline’s workflow specifies the order of operations (tasks) and their interdependence. Understanding numerous concepts, such as tasks upstream and downstream, might be useful in this situation. A job is a unit of labor that performs a specific task – data processing, in this example. Upstream is the point from which material reaches a pipeline, whereas downstream refers to its destination. Like water, data travels via the data pipeline. Also, upstream tasks are those that must be completed satisfactorily before downstream operations may begin.
The purpose of monitoring is to evaluate the performance of the data pipeline as well as its stages: if it maintains efficiency despite an increasing data load, whether it stays correct and consistent as it passes through processing stages, and whether no data is lost along the way.
Modern data pipelines are constructed with just a distributed architecture, which offers immediate failover and notifies consumers of component failures, application failures, or malfunction of particular other services. And if a node fails, another node inside the cluster takes over promptly without much effort.
Consider the following characteristics while developing your data pipeline architecture:
A data pipeline framework is a system that collects, organizes, and routes data to gain insights. Very many data points in the raw data may be irrelevant. Data pipeline architecture arranges data events to facilitate reporting, analysis, and utilization. According to business objectives, a mix of software protocols and technologies automates data management, visualization, conversion, and transmission from various sources.
