@TamD,

DLT doesn't currently support automatic liquid clustering. I've tried adding clusterByAuto='true' to the table properties for my DLT pipelines, and the pipeline builds successfully.

However, I don't think it actually works. I feel it's just treated as a customized tag in the table properties, as I have a 300GB streaming DLT table with this setting, and there are no clustering keys chosen when I run DESCRIBE TABLE EXTENDED.
