Matillion ETL Shared Job
CDC Microsoft SQL Server
Load change data from a Microsoft SQL Server table with Change Data Capture (CDC) enabled.
In Microsoft SQL Server, Change Data Capture (CDC) can be enabled on a table so that all data changes are captured into a separate change table. Loading this change data into your data warehouse using a Matillion ETL orchestration job is an efficient method to keep your tables up to date with your source SQL Server database.
This download contains two shared jobs that demonstrate how Matillion ETL can use the SQL Server CDC change data.
