@imay: Thanks. The uniq-model documentation had a syntax error in unique
key('user_id', 'username'). However, like Apache Impala supports update table
statement hence I would expect Apache Doris should support update statement
which is the basic feature in any SQL database.
Currently, performing update on any table model (aggregate, unique or
duplicate) throws the exception.

I am going to submit a request to add update table support.
