Understanding the intricacies of data pipelines — how they work, their key components, and their various types — empowers organizations to leverage their data more effectively and is a necessity in order to achieve such a significant advantage. 

In this blog, we will explore the basics of data pipelines, including definitions, key elements, types, and use cases across different industries.

What Is a Data Pipeline?

A data pipeline is essentially a set of automated processes that moves data from its source to a destination where it can be used for analysis and decision making. It may or may not include the transformation of data. The purpose of a data pipeline is to streamline and automate data handling so that data flows smoothly through its various stages without manual intervention.

Data Pipeline Architecture

A typical data pipeline architecture consists of the following:

• Data Source: The origin of data.
• Data Processing Engine: The system responsible for transforming and processing data.
• Data Storage: Where data is stored for later use.
• Data Orchestration: Coordinating the flow of data through the pipeline.
• Monitoring and Management: Overseeing the pipeline’s performance and addressing issues.

Data pipeline design focuses on handling data movement and transformation systematically. This automation reduces the risk of errors and inefficiencies that can occur with manual data handling. Setting up a data pipeline allows organizations to make sure that their data is consistently and accurately processed.

Key Elements of a Data Pipeline

Each component of a data pipeline plays a specific role in guaranteeing that the data is accurately and efficiently handled. The key elements of a data pipeline are:

1. Source

The source is the initial point where data is collected. It represents the origin of the data and can vary widely depending on the nature of the information and the systems involved. Common sources include:

• Relational Databases: Traditional databases that store data in structured tables with predefined schemas, like MySQL, PostgreSQL, and Oracle.
• SaaS Applications: Cloud-based applications that generate data as part of their operation, such as CRM systems (e.g., Salesforce), marketing platforms (e.g., HubSpot), and financial software (e.g., QuickBooks).
• APIs: Application Programming Interfaces that allow different systems to communicate and share data. APIs enable real-time data exchange between applications and services.
• External Files: Data files such as CSVs, JSONs, or XMLs that may be generated by other systems or manually created and uploaded.
• Streaming Data Sources: Real-time data streams from sources like IoT sensors, user activity logs, and social media feeds, which provide continuous data flows that need to be captured and processed immediately.

The data ingestion mechanism can vary based on the source, including methods such as:

• Push Mechanisms: Data is sent to the pipeline from the source at specified intervals or in response to specific events.
• API Calls: Data is pulled from the source using APIs that provide endpoints for retrieving information.
• Replication Engines: Tools that continuously replicate data from the source to the data pipeline for up-to-date information.
• Webhooks: Real-time notifications are sent from the source to the pipeline whenever data changes or specific events occur.

2. Processing Steps

After ingestion from the source, data undergoes a series of processing steps designed to transform, clean, and prepare the data for storage and analysis. These steps are:

• Transformation: Converting raw data into a format suitable for analysis. This may involve data normalization (standardizing values), aggregation (combining data points), and enrichment (adding contextual information).
• Cleansing: Identifying and correcting errors or inconsistencies in the data. This step verifies that the data is accurate and reliable by fixing incorrect values and addressing missing data.
• Sorting: Organizing data based on specific criteria, such as date, category, or relevance. Sorting helps in structuring data for easier retrieval and analysis.
• Deduplication: Removing redundant copies of data to avoid duplication issues and ensure that each data point is unique.
• Validation: Checking the data against predefined rules or constraints so that it meets the required quality standards. This process verifies that the data is complete, accurate, and adheres to expected formats.

Effective processing is important so that the data is not only clean and accurate but also structured in a way that aligns with the needs of the analysis or reporting that will follow.

3. Destination

The destination is where the processed data is stored and made available for further use. The choice of destination depends on the data storage and analysis requirements. Common destinations include:

• Data Lakes: Centralized repositories that store raw and unstructured data in its native format. Data lakes provide a flexible and scalable solution for handling large volumes of diverse data types.
• Data Warehouses: Structured storage systems optimized for querying and analysis. Data warehouses store processed and structured data, making it easy to perform complex queries and generate reports. Examples include Amazon Redshift, Google BigQuery, and Snowflake.
• Data Marts: A subset of data warehouses designed to support specific business functions or departments. Data marts focus on particular areas, such as sales or finance, to provide targeted insights.
• Cloud Storage: Scalable and cost-effective storage solutions provided by cloud services like AWS S3, Azure Blob Storage, and Google Cloud Storage. Cloud storage offers flexibility and ease of access to data.

Choosing the right destination involves considering data volume, access frequency, and integration with analytical tools, among other factors. The destination must support the efficient retrieval and analysis of data, allowing users to access the information they need to make informed decisions.

Types of Data Pipelines

Data pipelines come in various types, each designed to address different data processing needs and scenarios. Understanding the different types of data pipelines will help you select the right approach for your specific data requirements and operational context. Here’s a closer look at each type:

1. Batch Processing Pipelines

Batch processing involves running data pipelines at predefined intervals, such as daily or weekly. In batch processing, data is extracted, transformed, and loaded in bulk. This type of pipeline is efficient for handling large datasets but may not be suitable for applications that need real-time data.

2. Streaming Data Pipelines

Streaming data pipelines handle data in real time, processing it as it arrives. This is essential for applications that require immediate insights or responses. These pipelines support a continuous flow of data, providing up-to-date information and enabling real-time decision making.

3. ETL (Extract, Transform, Load) Pipelines

ETL pipelines do not simply transfer raw data, but provide a controlled environment where data undergoes rigorous processing to become actionable insights. These pipelines are designed to extract data from diverse sources, transform it according to specific business rules or formats, and then load it into a target system. This structured approach makes ETL pipelines crucial for organizations dealing with large volumes of data that require thorough processing before analysis.

4. ELT (Extract, Load, Transform) Pipelines

ELT pipelines extract data and load it directly into the destination before performing transformations. This approach allows for more flexible processing, as it enables the use of powerful processing engines at the destination to handle complex transformations.

Savant provides flexible data pipeline solutions designed to handle batch processing, real-time streaming data, and both ETL and ELT processes tailored to meet your specific needs.

Data Pipeline vs. ETL

Understanding the differences between data pipelines and ETL processes is important for selecting the right data management strategy. 

• Definitions and Scope

A data pipeline is a broad concept encompassing various methods of moving data from one place to another, which can include streaming, batch processing, and more. It refers to the entire end-to-end flow of data, from ingestion to storage, and may involve multiple steps and processes such as data cleansing, aggregation, and orchestration.

On the other hand, ETL (Extract, Transform, Load) is a specific type of data pipeline that focuses narrowly on extracting data from sources, transforming it into a usable format, and loading it into a destination database or data warehouse. While all ETL processes are data pipelines, not all data pipelines are ETL processes. ETL is often used in scenarios where structured data needs to be prepared for analysis in a systematic way.

• Differences in Latency and Flexibility

Data pipelines can handle real-time data processing with low latency, making them ideal for applications that need immediate or near-immediate data transfer and analysis, such as real-time analytics or financial trading platforms. Additionally, data pipelines can adapt to various data formats and sources, accommodating structured, semi-structured, or unstructured data, making them versatile for different business needs.

ETL processes often involve higher latency due to batch processing, where data is collected, processed in bulk, and loaded into a destination. This method suits scenarios where immediate data availability is less critical, like end-of-day reports or data warehouse updates. ETL is generally less flexible, focusing on structured data and following a fixed sequence — extract, transform, load — which prioritizes data consistency but can struggle with diverse data types or real-time needs.
