Both data ingestion and ETL are two essential components of a data management strategy. This guide highlights the importance of data ingestion in handling big data. It also provides insights into how data ingestion differs from ETL.
Most modern data stacks require managing large volumes of data. Therefore, data ingestion and ETL are two essential components of such a data stack.
Data ingestion involves the collection and import of raw data from various sources.
ETL is the process of extracting, transforming, and loading data into a data storage system.
In this section, we will explore the differences between data ingestion and ETL and their roles in a data management strategy.
Data ingestion is a subset of data integration.
It focuses on getting raw data into the target system as quickly and efficiently as possible. Other characteristics of data ingestion include the following points.
Data ingestion focuses on efficiently getting raw data into the target system. data integration involves more complex data transformations. It merges data from multiple sources.
Data ingestion is often done in real-time or near real-time. data integration is typically done on a scheduled basis (e.g., daily or weekly).
Data ingestion is a simpler process compared to data integration.
Data ingestion can handle both structured and unstructured data,
Data migration is moving data from one system to another. You can use ETL for data migration. In data migration, you only need to move data from one source to another. However, ETL is specifically suitable when you need to transform data.
ETL is a process with 3 steps. Those are extract, transform, and load.
Extract: Data is extracted or pulled from one or more sources, such as databases or files.
Transform: The data is transformed to fit the target system's schema and requirements. This includes tasks like data cleaning, data enrichment, and data standardization.
Load: The transformed data is loaded or pushed into the target system. This target system can be a data warehouse.
ETL can also involve automation and aggregation of data. these processes enable organizations to efficiently process and analyze large volumes of data. The goal of ETL is to ensure that data is accurate, complete, and consistent in the target system. It allows organizations to make informed decisions based on high-quality data.
|Definition||The initial step in data integration is to move raw data from its source to a central destination for storage.||ETL is s process to organize ingested data in a specified format and store it in a repository like a warehouse.|
|What is it||Data ingestion is a process. You can use various methods to ingest data into a staging area.||ETL works on the data after it comes to the staging area. ETL standardizes data.|
|Purpose||Its goal is to establish a centralized repository for all data. Then the repository is made available for the relevant parties.||Increase the accessibility of your data by standardizing them. This helps to derive insights from data.|
|Tools||Apache Kafka, Matillion, Apache NiFi, Wavefront, Stitch data, Funnel.||Portable, Xplenty, Informatica, AWS Glue|
The data management strategy of an organization involves several steps.
Data Ingestion sits middle of the data management strategy. Data ingestion is typically the first step in a data processing pipeline. ETL, data processing and analytics tools will follow it.
Data ingestion plays a critical role in enabling streaming ETL and real-time data processing.
Undeniably, it's a key component of the modern data stack.
There are three main types of data ingestion techniques. Those are
Batch data ingestion
Real-time streaming data ingestion
Source data ingestion
Batch data ingestion collects and loads data in the form of large chunks at regular intervals. This technique is useful for non-time-sensitive tasks and can handle high data volumes.
Real-time streaming data ingestion transfers data from the source to the destination in near real-time. This method offers low data latency.
Source data ingestion collects data directly from the source without staging the data. This technique is suitable for data sources that do not require significant transformation.
Data ingestion is the process of extracting raw data from various sources. This data is loaded into a destination for further analysis.
A data ingestion pipeline can help efficiently scale up and down the process to meet an organization's needs.
Disparate sources of data require appropriate data transformation and cleansing.
Data can be ingested from various sources. Some examples are databases, cloud services, and third-party applications.
Following the best practices for data ingestion ensures standardized, cleaned, and high-quality data. This leads to more accurate and effective data analysis and decision-making.
Connectors are tools that integrate different data sources. These sources include SaaS apps, business intelligence platforms, Microsoft SQL Server, and Snowflake.
Connectors for SaaS apps integrate data from cloud-based applications with other sources.
Connectors for business intelligence platforms facilitate data analysis and reporting.
SQL Server and Snowflake connectors make it easy to transfer data between different data storage platforms.
We understand the need for a seamless flow of data between different systems. That's why we offer over 300 hard-to-find ETL connectors. You can easily integrate them into your data workflows. And, if you're in need of a custom connector, we offer lightning-fast custom development.
Apache Kafka is a tool that captures data in real-time. Kafka is being used by 80% of Fortune 100 companies. However, managing Apache Kafka can be a complicated task, as stated by Nasdaq. To address this, the co-founders of Apache Kafka established Confluent, which is a data platform for managing Kafka.

NiFi is an open-source platform to automate data flow across systems. Initially, it was built by Onyara and was first used by the US NSA to understand sensor data.
In 2014, the software was released under an open-source license. In 2015, Onyara was acquired by Hortonworks.
Today, Hortonworks has merged with Cloudera and provides commercial support for NiFi.

ETL tools simplify this whole process of extracting data from one source, transforming data, and loading data to another source. This enables organizations to process and analyze large volumes of data quickly and efficiently.
ETL connectors are used to connect different data sources and targets in an ETL workflow. The process involves the following steps.
One of the first steps to getting started with ETL is to identify the data sources and define the data extraction process.
Extract: The connector pulls data from one or more sources. These sources can be databases, files, or APIs.
Transform: The connector then transforms the data to fit the target system's requirements. This may include tasks like data cleansing, data enrichment, and data standardization.
Load: The transformed data is then loaded into the target system. This target system can be a data warehouse.
The data can be loaded into tables, views, or other structures within the target system.
ETL tools are more suitable for high-volume data processing compared to ELT tools.
ETL tools provide more reliable data quality due to data transformations and cleaning.
ETL tools can easily handle unstructured data compared to traditional data warehousing solutions.
ETL tools can automate the process of loading data into data warehouses. This automation makes the process quicker and more efficient.
Data within the ETL process should have a well-defined schema.
Using a data lake to store large volumes of data before it is processed in an ETL pipeline. This is especially good practice for unstructured data.
Having a well-designed data pipeline. It allows organizations to process large volumes of data in real time.
Reducing data latency in an ETL pipeline to ensure that data is up-to-date.
Following data integrity best practices is important to ensure that the data is
You need to maintain the same data format. It ensures that data is consistent and can be analyzed effectively. To do that, you need to follow the below steps.
Adopting consistent data ingestion patterns
Ensuring that all data sources adhere to the same format
Transforming disparate sources of data ensure that data is consistent and in the desired format.
Data cleanse removes any errors or duplicates and
Standardizes data to make it adheres to the same format across all sources
Altering data in a way they can be effectively analyzed.
