Summarize with AI:

The most prominent ETL and ELT tools to transfer data from S3 include:

Airbyte

Fivetran

Stitch

Matillion

These ETL and ELT tools help in extracting data from S3 and other sources (APIs, databases, and more), transforming it efficiently, and loading it into a database, data warehouse or data lake, enhancing data management capabilities. Airbyte distinguishes itself by offering both a self-hosted open-source platform and a Cloud one..

What is ETL?

ETL (Extract, Transform, Load) is a process used to extract data from one or more data sources, transform the data to fit a desired format or structure, and then load the transformed data into a target database or data warehouse. ETL is typically used for batch processing and is most commonly associated with traditional data warehouses.

‍What is ELT?

More recently, ETL has been replaced by ELT (Extract, Load, Transform). ELT Tool is a variation of ETL one that automatically pulls data from even more heterogeneous data sources, loads that data into the target data repository - databases, data warehouses or data lakes - and then performs data transformations at the destination level. ELT provides significant benefits over ETL, such as:

Faster processing times and loading speed
Better scalability at a lower cost
Support of more data sources (including Cloud apps), and of unstructured data
Ability to have no-code data pipelines
More flexibility and autonomy for data analysts with lower maintenance
Better data integrity and reliability, easier identification of data inconsistencies
Support of many more automations, including automatic schema change migration

For simplicity, we will refer to AWS ETL tools, particularly S3 ETL, as the benchmark for all data integration solutions, encompassing both ETL and ELT methodologies. This approach streamlines the integration process, allowing seamless data integration from various sources.

How data integration from S3 to a data warehouse can help

Companies might do S3 ETL for several reasons:

Business intelligence: S3 data may need to be loaded into a data warehouse for analysis, reporting, and business intelligence purposes.
Data Consolidation: Companies may need to consolidate data with other systems or applications to gain a more comprehensive view of their business operations
Compliance: Certain industries may have specific data retention or compliance requirements, which may necessitate extracting data for archiving purposes.

Overall, ETL from S3 allows companies to leverage the data for a wide range of business purposes, from integration and analytics to compliance and performance optimization.

Top S3 ETL tools

Here are the top S3 ETL tools based on their popularity and the criteria listed above:

1. Airbyte

Airbyte is the leading open-source ELT platform, created in July 2020. Airbyte offers the largest catalog of data connectors—350 and growing—and has 40,000 data engineers using it to transfer data, syncing several PBs per month, as of June 2023. Major users include brands such as Siemens, Calendly, Angellist, and more. Airbyte integrates with dbt for its data transformation, and Airflow/Prefect/Dagster for orchestration. It is also known for its easy-to-use user interface, and has an API and Terraform Provider available.

What's unique about Airbyte?

Their ambition is to commoditize data integration by addressing the long tail of connectors through their growing contributor community. All Airbyte connectors are open-source which makes them very easy to edit. Airbyte also provides a Connector Development Kit to build new connectors from scratch in less than 30 minutes, and a no-code connector builder UI that lets you build one in less than 10 minutes without help from any technical person or any local development environment required..

Airbyte also provides stream-level control and visibility. If a sync fails because of a stream, you can relaunch that stream only. This gives you great visibility and control over your data.

Data professionals can either deploy and self-host Airbyte Open Source, or leverage the cloud-hosted solution Airbyte Cloud where the new pricing model distinguishes databases from APIs and files. Airbyte offers a 99% SLA on Generally Available data pipelines tools, and a 99.9% SLA on the platform.

2. Fivetran

Fivetran is a closed-source, managed ELT service that was created in 2012. Fivetran has about 300 data connectors and over 5,000 customers.

Fivetran offers some ability to edit current connectors and create new ones with Fivetran Functions, but doesn't offer as much flexibility as an open-source tool would.

What's unique about Fivetran?

Being the first ELT solution in the market, they are considered a proven and reliable choice. However, Fivetran charges on monthly active rows (in other words, the number of rows that have been edited or added in a given month), and are often considered very expensive.

Here are more critical insights on the key differentiations between Airbyte and Fivetran

3. Stitch Data

Stitch is a cloud-based platform for ETL that was initially built on top of the open-source ETL tool Singer.io. More than 3,000 companies use it.

Stitch was acquired by Talend, which was acquired by the private equity firm Thoma Bravo, and then by Qlik. These successive acquisitions decreased market interest in the Singer.io open-source community, making most of their open-source data connectors obsolete. Only their top 30 connectors continue to be maintained by the open-source community.

What's unique about Stitch?

Given the lack of quality and reliability in their connectors, and poor support, Stitch has adopted a low-cost approach.

Here are more insights on the differentiations between Airbyte and Stitch, and between Fivetran and Stitch.

Other potential services

4. Matillion

Matillion is a self-hosted ELT solution, created in 2011. It supports about 100 connectors and provides all extract, load and transform features. Matillion is used by 500+ companies across 40 countries.

What's unique about Matillion?

Being self-hosted means that Matillion ensures your data doesn’t leave your infrastructure and stays on premise. However, you might have to pay for several Matillion instances if you’re multi-cloud. Also, Matillion has verticalized its offer from offering all ELT and more. So Matillion doesn't integrate with other tools such as dbt, Airflow, and more.

Here are more insights on the differentiations between Airbyte and Matillion.

5. Airflow

Apache Airflow is an open-source workflow management tool. Airflow is not an ETL solution but you can use Airflow operators for data integration jobs. Airflow started in 2014 at Airbnb as a solution to manage the company's workflows. Airflow allows you to author, schedule and monitor workflows as DAG (directed acyclic graphs) written in Python.

What's unique about Airflow?

Airflow requires you to build data pipelines on top of its orchestration tool. You can leverage Airbyte for the data pipelines and orchestrate them with Airflow, significantly lowering the burden on your data engineering team.

Here are more insights on the differentiations between Airbyte and Airflow.

6. Pentaho

Pentaho is an ETL and business analytics software that offers a comprehensive platform for data integration, data mining, and business intelligence. It offers ETL, and not ELT and its benefits.

What is unique about Pentaho?

What sets Pentaho data integration apart is its original open-source architecture, which allows for easy customization and integration with other systems and platforms. Additionally, Pentaho provides advanced data analytics and reporting tools, including machine learning and predictive analytics capabilities, to help businesses gain insights and make data-driven decisions.

However, Pentaho is also an Enterprise product, so hard to implement without any self-serve option.

7. Informatica PowerCenter

Informatica PowerCenter is an ETL tool that supported data profiling, in addition to data cleansing and data transformation processes. It was also implemented in their customers' infrastructure, and is also an Enterprise product, so hard to implement without any self-serve option.

8. Singer

Singer is also worth mentioning as the first open-source JSON-based ETL framework. It was introduced in 2017 by Stitch (which was acquired by Talend in 2018) as a way to offer extendibility to the connectors they had pre-built. Talend has unfortunately stopped investing in Singer’s community and providing maintenance for the Singer’s taps and targets, which are increasingly outdated, as mentioned above.

9. Rivery

Rivery is another cloud-based ELT solution. Founded in 2018, it presents a verticalized solution by providing built-in data transformation, orchestration and activation capabilities. Rivery offers 150+ connectors, so a lot less than Airbyte. Its pricing approach is usage-based with Rivery pricing unit that are a proxy for platform usage. The pricing unit depends on the connectors you sync from, which makes it hard to estimate.

10. HevoData

HevoData is another cloud-based ELT solution. Even if it was founded in 2017, it only supports 150 integrations, so a lot less than Airbyte. HevoData provides built-in data transformation capabilities, allowing users to apply transformations, mappings, and enrichments to the data before it reaches the destination. Hevo also provides data activation capabilities by syncing data back to the APIs.

All those ETL tools are not specific to S3, you might also find some other specific data loader for S3 data. But you will most likely not want to be loading data from only S3 in your data stores.

Which data can you extract from S3?

Amazon S3's API provides access to a wide range of data types, including:

1. Object data: This includes the actual files stored in S3 buckets, such as images, videos, documents, and other types of files.
2. Metadata: S3 stores metadata about each object, including information such as the object's size, creation date, and last modified date.
3. Access control data: S3 provides access control mechanisms to restrict access to objects in a bucket. The API provides access to information about access control policies and permissions.
4. Bucket data: S3 buckets are containers for objects. The API provides access to information about buckets, such as their names, creation dates, and region.
5. Logging data: S3 can log access requests to objects in a bucket. The API provides access to these logs, which can be used for auditing and compliance purposes.
6. Inventory data: S3 can generate inventory reports that provide information about the objects stored in a bucket. The API provides access to these reports.
7. Metrics data: S3 can generate metrics about the usage of a bucket, such as the number of requests and the amount of data transferred. The API provides access to these metrics.

How to start pulling data in minutes from S3

If you decide to test Airbyte, you can start analyzing your S3 data within minutes in three easy steps:

Step 1: Set up S3 as a source connector

1. Open the Airbyte dashboard and click on "Sources" from the left-hand menu.
2. Click on the "Create Source" button and select "S3" from the list of available connectors.
3. Enter a name for your S3 source and click on "Next".
4. Enter your AWS access key ID and secret access key in the respective fields. You can find these credentials in your AWS account under "Security Credentials".
5. Select the AWS region where your S3 bucket is located from the dropdown menu.
6. Enter the name of your S3 bucket in the "Bucket Name" field.
7. If your S3 bucket is not in the root directory, enter the path to the directory in the "Path Prefix" field.
8. If you want to include only certain files in your data sync, you can enter a file pattern in the "File Pattern" field. For example, "*.csv" will only include CSV files.
9. Click on "Test" to verify your credentials and connection to the S3 bucket.
10. If the test is successful, click on "Create Source" to save your S3 source connector.Once your S3 source connector is set up, you can use it to create a new Airbyte pipeline and sync data from your S3 bucket to your destination of choice.

Step 2: Set up a destination for your extracted S3 data

Choose from one of 50+ destinations where you want to import data from your S3 source. This can be a cloud data warehouse, data lake, database, cloud storage, or any other supported Airbyte destination.

Step 3: Configure the S3 data pipeline in Airbyte

Once you've set up both the source and destination, you need to configure the connection. This includes selecting the data you want to extract - streams and columns, all are selected by default -, the sync frequency, where in the destination you want that data to be loaded, among other options.

And that's it! It is the same process between Airbyte Open Source that you can deploy within 5 minutes, or Airbyte Cloud which you can try here, free for 14-days.
