@Christopher Teljstedt Thanks for using Microsoft Q&A !!
Unfortunately TTL feature is not available for Azure Synapse Analytics and it is meant for Azure Data Factory Only. Please refer to the documentation to get data integration differences of ADF and Synapse Analytics.
I will internally share this feedback with the products team however, I also suggest you to please provide this as a feedback at Synapse Analytics Uservoice so that community can upvote and products team can work on including this feature in future releases of Synapse Analytics.
Thanks you.
Saurabh
