Qlik Replicate

Log-based change data capture and replication engine for moving data from enterprise databases and mainframes with minimal source impact.

Visit Qlik Replicate Alternatives

Qlik Replicate (formerly Attunity Replicate) is a dedicated CDC and bulk-replication engine that reads transaction logs from databases such as Oracle, SQL Server, DB2 and mainframe systems, replicating changes to targets including cloud warehouses, Kafka and other databases with near-zero impact on source systems. It is agentless for many sources, uses a GUI-driven setup rather than hand-written scripts, and is commonly deployed for migrating on-premises databases to the cloud or feeding real-time analytics pipelines. As part of Qlik's data integration portfolio (alongside the broader Qlik Talend Cloud), its CDC capability is sold within the same edition structure as Talend, metered by data volume, job executions and duration rather than published per-seat pricing.
