AWS Database Migration Service (AWS DMS) has expanded its functionality by supporting parallel apply when using Redshift as a target during on-going replications. Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. You can start with just a few hundred gigabytes of data and scale to a petabyte or more. By taking advantage of the multithreaded CDC task settings, you can improve the performance of your on-going replications from any DMS supported sources to Amazon Redshift.
