Hi,According to this link,&nbsp;??Too high cardinality is not suitable for 
dictionary??. Have you tried&nbsp;other encoding methods&nbsp; such as 
??fixed_length??&nbsp;for the UHC column? I am not sure maybe this is not the 
best solution but it works for me.
You can also check "Deal with Ultra-High-Cardinality Columns" section 
in&nbsp;this page.
