Overview
Estuary Flow
Estuary Flow is a managed data operations platform designed to help you build real-time data pipelines without the complexity of managing infrastructure. You can connect to over 100 different connectors, including databases, SaaS applications, and cloud storage, to move data instantly to your preferred destinations. The platform handles the heavy lifting of data capture, transformation, and materialization, ensuring your data stays synchronized across your entire stack.
It is built for data engineers and developers who need to move large volumes of data with millisecond latency. You can manage your pipelines through a user-friendly web interface or via a CLI for more technical workflows. Whether you are migrating databases, powering real-time analytics, or synchronizing search indexes, the platform scales automatically to meet your data volume needs while maintaining strict data integrity.
Qlik Replicate
Qlik Replicate helps you move data at scale across your entire organization without manual coding. You can automate the end-to-end replication process, from source discovery to target ingestion, ensuring your analytics teams always work with the most current information. By using change data capture technology, you minimize the impact on your source systems while maintaining high-performance data streams.
You can connect a vast array of sources, including legacy mainframes, SAP applications, and relational databases, to modern cloud targets like Snowflake, Azure, or AWS. The platform is designed for data engineers and architects who need to eliminate the complexity of ETL development. It allows you to focus on deriving value from your data rather than managing the underlying movement mechanics.
