Sync SQL Server Transaction Logs to Redshift
Nothing exists natively from SQL Server so 3rd party is your best bet. Homegrown is not recommended because SQL Server's transaction log format is not published so it'll be a pretty steep curve.

sp_BlitzErik's suggestion to talk to the vendors is the best place to start. If you don't have the right contacts or not enough vendors to evaluate, check out the RS data integration partners on https://aws.amazon.com/redshift/partners/1

You can also contact AWS directly or post a feature request on the AWS RS forum https://forums.aws.amazon.com/forum.jspa?forumID=155&amp;start=0
