Compare the features & pricing of 2023's top ETL tools.

Businesses rely on data to make critical decisions for their sales, marketing or any important task they may undertake. However, this data is present in various formats and sizes and stored on various databases or files. To analyze this data you need certain tools to extract this data, transform it into a suitable format and finally load it to a destination storage such as a data warehouse. These tools are referred to as ETL(Extract, Transform, Load) tools. 

Today, the majority of businesses use an ETL tool as part of their data integration process. ETL tools are renowned for their efficiency, cost-effectiveness, and scalability to broader data management approaches. In this article, you will understand what ETL is and also explore the different types of ETL tools. In addition, you will learn about some critical factors necessary to choose the best ETL tool. So, read along to discover the best ETL tools that are widely used in the market.

What is ETL?

In the digital era, data plays a very big part. You can store this data in excel sheets or in databases or even as images and videos. However, when you want to analyze or use this data, you need to consolidate it into one format. This is where ETL plays a role. 

In simple terms, ETL is an acronym for Extract, Transform and Load. You extract data from a source, transform it into a relevant format and then load this data into a data warehouse or a database. So, companies either create their own standard ETL pipelines or prefer to use automated ETL tools like Fivetran.

The end-to-end ETL process involves the following stages:

  • Extraction: This stage involves the extraction of data be it structured or unstructured from various sources such as websites, Customer Relationship Management(CRM) platforms, applications, databases, SaaS software, files, marketing platforms, or any other data source. The data loads into a staging area after extraction is finished and is ready for the next stage - transformation.
  • Transformation: The transformation stage prepares the extracted data by cleaning and formatting it. The objective is to get the data ready for querying in the target storage such as a data warehouse like Google BigQuery, Redshift, and Snowflake or databases such as MongoDB, and PostgreSQL.

The extracted data must be transformed into a standard format to fulfill the target database's schema requirements. This is done by running a number of functions and applying a set of rules to the data. The degree of manipulation necessary for ETL transformation totally depends on the extracted data and the demands of the business. Some of the basic transformations involved in this stage are as follows:

  • Cleaning: Filling up the missing values with some default values or checking for any date format consistency, etc.
  • Deduplication: Identifying & removing duplicate records.
  • Format Standardization: Formatting something in accordance with a set of guidelines so that its values and structure are compatible with the intended use case, for example, measurement unit conversion, date/time conversion, etc.
  • Key Restructuring: Finding important relationships between tables
  • Loading: The transformed data must now be loaded into the desired data destination, such as a database, data warehouse, or data lake. Data can be loaded in 2 different ways: incremental loading or all at once i.e. full loading. A full loading transfers all records from the transformation assembly line to the target warehouse or database. This may result in redundant data, if not checked. Therefore, one of the important factors to take into account throughout the load process is knowing the task that the target environment is expected to perform. When loading data, you could have a detrimental effect on the host system depending on the volume, structure, target, and load type.

What are ETL tools?

Data is only meaningful if it can be converted and used for operational and business insights. Hence, ETL tools are essential for delivering business intelligence to organizations of all sizes. Organizations gather data from numerous sources. ETL Tools help streamline the process of extracting data from multiple sources, transforming it into a defined format, and effectively loading it into the data destination. Now you can use this data to load it into Business Intelligence tools like Tableau, Power BI or others to analyze this data. 

ETL tools organize and automate the flows of data from the data sources in order to generate reliable information. The majority of the aforementioned process can be entirely streamlined depending on the ETL tool. Pre-built data connectors offered by ETL tool vendors require little to no coding to extract, transform, and load data to a target system. This eliminates the requirement for challenging data intake, API management, and other duties.

To understand the different types of ETL tools used in the industry, read the next section to find out more.

What are the types of ETL tools?

Depending on various factors, like cloud-based, on-premise, real-time and others, you can basically divide the ETL tools into the following categories:

1. Custom ETL tools

Businesses with internal data engineering and support resources can design and build their own tools and pipelines using languages such as  SQL, Python, and Java.  Although this strategy provides the most flexibility, it also demands the most work and effort. Additionally, users must carry out their own testing, documentation creation, maintenance, and continued development under this type.

2. Batch ETL tools

For many firms, the only workable ETL method up until very recently was batch processing in on-premises tools. In the past, processing huge amounts of data required a lot of time and energy and could quickly exhaust a company's computing and storage capacity during business hours. Hence, for businesses, it made more sense to use batch data processing with ETL tools during off-peak hours. These tools performed data extraction, transformation, and loading in batches.

3. Real-time ETL tools

Real-time ETL tools are used to extract, transform, and load data onto the target system in real time. For some data updates, batch processing works fine. However, we now need real-time access to data from various sources more frequently. Real-time demand is forcing us to process data in real-time rather than in batches, using a distributed paradigm and streaming capabilities. As a result, these ETL tools are growing in popularity as businesses look for insights that can be put to use right away. Numerous near real-time ETL tools are offered, both commercially and through open source.

4. On-premise ETL tools

Many businesses use older systems with on-premises data and repository configuration. Data security is the main driver for such an arrangement. Due to this, firms prefer to have an ETL tool installed on-site.

5. Cloud ETL tools

Companies are increasingly using cloud-based ETL tools to ingest data from various web applications or on-premises sources. These tools are deployed in the cloud. As almost all data and applications are supported on the cloud, it becomes easier to extract and load data to the ETL tool. This also saves the resources and other costs to set up the ETL tool. Cloud ETL tools offer high availability, elasticity, and low latency, allowing resources to scale and match the current demands for data processing.

 6. Open-source ETL tools

Numerous open-source ETL tools have been developed during the previous decade. As these ETL tools are easily accessible, a huge testing community constantly provides feedback on them to enhance or add to their functionality. Many of these open-source ETL tools offer a graphical interface for building and running pipelines.

7. Hybrid ETL tools     

Integrating the features of the above ETL tool types will give you a hybrid ETL tool. So, multiple ETL tasks can be handled at scale by a single ETL platform.

Key factors to evaluate ETL tools

As discussed above, businesses have a lot of flexibility to pick an ETL tool. The optimal ETL tool will vary depending on a number of aspects, including the anticipated use cases, pricing, the location of the source data, the type of data to be moved, the need for scalability, and the amount of knowledge needed to use it. Some businesses prefer to create their own ETL pipelines, and some choose automated tools either on-premise or cloud-based. Choosing the right ETL tool for your use case may get challenging. Hence, we have listed below some of the critical factors you should keep in mind while selecting the best ETL tool for your company.

  • Use case: Use case analysis is a crucial factor when choosing your ETL tools. You might not require a solution as robust as large enterprises with complicated datasets if your business is small or if your data analysis needs are low.
  • Data connectors: Which data sources is your team most interested in utilizing? When the need arises, how much effort are you willing to put into developing a new integration? The data sources used by many startups and small companies are generally uniform. While choosing the ideal ETL tool for your use case, your data team should choose ETL tools supporting a variety of integration options, be it a data source or a data destination including the ones you will be using.
  • Easy-to-use iterface: Who will be using the data, how will it be loaded, and how will it be used? Ensure that the ETL tool has an interactive user interface and is easy to set up. This makes sure that your team be it technical experts or non-technical users, gets an amazing experience while managing data-related tasks and creating data pipelines.
  • Scalability: Keep in mind that your data requirements will increase as your company grows. To meet the demands of your expanding business, the ETL tool should support performance optimization capabilities along with other resources needed to scale your pipeline.
  • Low latency: Real-time ETL tools are gaining popularity among enterprises as the demand for quick data collection and analysis has grown. Real-time data is crucial since some decisions must be taken immediately. While some source data connectors will have latency requirements, data should move through your ETL process with as little latency as feasible.
  • Pricing: Businesses should take into account not just the cost of the tool itself, but also the price of the infrastructure and human resources required to sustain the ETL tool over the long term.
  • Built-in monitoring & security: A monitoring system that delivers real-time updates on job progress should or has been integrated into the ETL tools to ensure efficient process execution. The level of security and compliance is equally important to other factors. To ensure that sensitive data is protected and only shared with the right users, companies need to make sure that the ETL tool vendor meets the security requirements.
