Data Replication Platform Comparison
Fivetran
Cloud-based: Fully managed platform for replicating data from various sources to cloud data warehouses.
Features: Automatic schema mapping, data quality checks, and real-time replication.
Strengths: Easy to use, scalable, and supports a wide range of source and destination systems.
From Oracle to SAP, the Fivetran platform supports the world’s largest workloads using a variety of database replication methods.
Utilizing log-based CDC, Fivetran can rapidly detect all of your data changes and replicate them to your destination via a simple setup, efficient processes and minimal resources.
Fivetran supports log-free database replication with teleport sync, using compressed snapshots to replicate data from supported sources to their destination with just a read-only user.
Replicate large volumes of data in real-time with Fivetran's high-volume agent database connectors.
Stitch
Cloud-based: Another popular choice for data replication.
Features: Incremental loading, data transformation, and support for various data sources and destinations.
Strengths: Flexible, customizable, and offers a free tier for small-scale projects.
Stitch a cloud-based, ETL data pipeline. ETL is short for extract, transform, load, which are the steps in a process that moves data from a source to a destination.
That being said, keep in mind that Stitch isn’t:
A data analysis service. We have many analytics partners who can help here, however.
A data visualization or querying tool. Stitch only moves data. To analyze it, you’ll need an additional tool. Refer to our list of analysis tools for some suggestions.
A destination. A destination is typically a data warehouse and is required to use Stitch. While we can’t create one for you, you can use our Choosing a destination guide if you need some help picking the right destination for your needs.
Matillion
ETL tool: Primarily designed for data integration and transformation.
Features: ETL capabilities, data warehousing, and cloud integration.
Strengths: Powerful ETL features and integration with various cloud platforms.
The term "Medallion Data Architecture" was raised to prominence primarily by Databricks. It is a comprehensive blueprint for overall structuring within a Data Lakehouse or Cloud Data Warehouse. This design philosophy classifies data into three distinct layers: bronze, silver, and gold. Pipelines govern the data flowing between the layers from bronze to gold.
Data is first replicated - copied - from its source into the foundational bronze layer. This step doesn't change any aspect of the data but provides a single unified technology interface for the data team to access everything they need. It also safeguards against disruptions such as temporary connectivity issues or the loss of historical data.
Next, the data is transitioned into the silver layer. This is a consolidated, standardized, and system-neutral representation of data from all the diverse sources. Performing this integration requires data transformation to address the inevitable inconsistencies caused by having many different source applications. Data models in the silver layer are concise and succinct data structures devoid of redundancy. Every single data definition resides in just one place. This makes data easy to find and unambiguous for downstream users in the next layer.
The silver layer is an efficient and compact central repository, but its compactness means that data retrieval can be complex - requiring many relational joins. This makes it less suitable for direct end-user consumption. This is where the gold layer becomes valuable as a presentation layer, aiming to enhance the accessibility of silver layer data. Structural rearrangements make the data much more user-friendly during this second data transformation stage. A star schema is the most common choice of data model in the gold layer.
Airbyte
Open-source platform: Provides a flexible and customizable data replication solution.
Features: Connectors for various sources and destinations, data transformation, and scheduling capabilities.
Strengths: Community-driven, customizable, and suitable for organizations with specific requirements.
Key Factors to Consider:
Features: Evaluate the specific features offered by each platform, such as data quality checks, transformation capabilities, and support for your source and destination systems.
Ease of Use: Consider the platform's user interface, documentation, and learning curve.
Scalability: Ensure the platform can handle your current and future data volume and complexity.
Cost: Compare pricing models and costs associated with each platform.
Integration: Evaluate how well the platform integrates with your existing tools and infrastructure.
By carefully considering these factors, you can select the data replication platform that best aligns with your organization's needs and goals.
