Data Scalability

Stelo automatically merges your high-volume enterprise data streams into a delta lake without coding. Start with the data you need now and add more later without further licensing. 

Functionality Icon_Green

Functionality and Ease-of-Use

Use an intuitive GUI to easily ingest data and transfer it to where you need it. Once set up, Stelo reliably operates in the background without dedicated support to maintain and manage.

Resilient Data Connectivity Icon_Noun 4636104_Green

Resilient Data Connectivity

Save time and avoid risk if a connection breaks. Stelo uses data logging to preserve data integrity before immediately resuming data automation when the connection is reestablished. No re-baselining required.

Integrated Data Insights Icon_Noun 2198129_Green

Integrated Data Insights

Stelo seamlessly moves structured and unstructured data into a managed data lake or data lakehouse for use in visualization and data processing technologies such as artificial intelligence (AI) applications.

“Stelo was willing to engage with us on our unique needs, and the team was very responsive when we asked for extended functionality.”
Stephen Tiepel
Senior Director of Data at Penn Foster
“It’s set it and forget it. I no longer need to babysit the data. I go in there and everything is green and working, giving us the confidence that the replication is happening under the surface and giving us up-to-the-second data.”
Gregory R. Werner
IT Director at NWTF
“The Stelo proof of concept answered most of the questions we had, and Stelo just worked. The GUI let us easily pick the schema we wanted, and we learned that the UI is deep, the deeper you go the more configuration capabilities there are. Latency was excellent, and scaling was great.”

Penn Foster Delta Lakes Case Study

Stelo and Penn Foster Create an Adaptable Data Lakehouse

Penn Foster mainly uses structured data but will soon leverage unstructured data types to foster machine learning practices and improve learner analytics. Learn how Stelo flows their data into Databricks on Azure without demanding coding.


Real-Time Data Availability with Long-Term System Flexibility

Telesure Investment Holdings rapidly deployed Stelo to move IBM for i data into an SQL Server warehouse for timely stakeholder insights. Kafka support was added to feed a data lake and avoid vendor lock-in as needs evolve.


Scaling Business Operations with Cost-Efficient Data Integration

Stelo’s load-based pricing enabled a retail bank to expand its table replication count while adding target systems, including a remote Amazon Web Service (AWS) data lake solution. Future plans include full cloud migration.


Data lake, delta lake, data lakehouse: what's the difference? And where do data warehouses fit in?

These terms can get confusing, but understanding the underlying pieces is critical for ensuring you set up a cost-effective data integration architecture.

A data warehouse is a relatively limited-volume data repository and processor of aggregated structured data from relational sources. The replicated data mirrors the source database to provide traditional query processing. Common applications include data analytics and business intelligence (BI). A data lake is a large-volume repository of aggregated structured and unstructured data from relational and non-relational sources. Key applications include machine learning (ML), and artificial intelligence (AI).

A data lakehouse is a big-data architecture that combines benefits of both data warehousing and data lakes, supporting data analytics, BI, ML and AI applications.
A delta lake is an open-source storage layer placed above a data lake to create a data lakehouse, providing critical data governance and scalability for future-proofing your organization.

Stelo's delta lakes connector is compatible across your technology stack to efficiently populate your data lake. Our process can work in tandem with your traditional data warehouse to scale your data pipeline into a cost-effective data management solution. Read our "5 Questions to Answer Before You Start Moving Your Data to Delta Lakes" blog post to learn more about how to get started.

Do you support my replication pairing?

The short answer is yes.

Stelo takes full advantage of open standards such as DRDA, SQL, ODBC, and JDBC. to maximize compatibility and interoperability within an enterprise network. We are an active member of The Open Group software industry consortium, which was responsible for the adoption of DRDA as an industry standard for database interoperability.

Currently, Stelo supports more than thirty ODBC databases and our Kafka interface can also be used to communicate with cloud-based streaming services such as Azure Event Hubs for Kafka, the Oracle Cloud Infrastructure Streaming service, Amazon Managed Streaming for Apache Kafka, and IBM Event Streams. Stelo can also populate Azure Data Lake Storage Gen2 (ADLSg2) and similar NoSQL data repositories.

Stelo continues to use our open standards approach to ensure that we meet emerging replication requirements. We are continually adding support for new technologies while supporting legacy systems. Stelo is designed to grow with your organization rather than lock you in to any specific database platforms.

Why is real-time change data capture important?

Analyzing a company’s ongoing transactional or operational data can provide key insights that drive business decisions and processes. Many companies offload these operations to other databases, data warehouses, or data lakehouses to reduce source system load and save costs. However, replicating dynamic data from multiple source databases to one or more destination application requires real-time CDC to ensure all updates are automatically and reliably reflected. In other words, business insights are only effective if data changes are accurately captured and delivered across the connected databases over time.

CDC is typically the first stage in the data ingestion process and represents the “extraction phase” in the ETL and ELT approaches. CDC strategies often demand a tradeoff between latency tolerance and change volume requirements, but Stelo’s approach provides the ideal balance between fast, high-volume performance and lossless data capture. Our process can simultaneously propagate a source system’s information changes and structure updates to destination platforms so that the data appears in the correct sequence at the same time. In addition, the cost-efficient method merges incoming data flows into one stream, as opposed to using many streams, which becomes expensive.
