Thanks @RiyazAliM . I want to use cluster by auto, because the data will get queried and aggregated several different ways by different business users.  I did try your code above anyway, specifying the columns to cluster by.  The pipeline ran without error, but SHOW TBLPROPERTIES does not show that any clustering has been applied.  These are the only properties set on the table:

delta.autoOptimize.autoCompact
delta.autoOptimize.optimizeWrite
delta.enableChangeDataFeed
delta.minReaderVersion
delta.minWriterVersion
pipelines.pipelineId

@Louis_Frolio- if automatic liquid clustering is applied to DLT table during DLT maintenance jobs -- which I believe are managed automatically by Databricks -- when should I expect to see clustering information in the table properties?

Cheers!
