Re: [I] Read string as Utf8View in sqllogictest [datafusion]

alamb commented on issue #13408:

   I am not sure if you have seen the great `string` patter in sqllogictest from @goldmedal  yet: https://github.com/apache/datafusion/tree/main/datafusion/sqllogictest/test_files/string
   
   Basically it lets you write one set of tests and then verify those tests work with all the different types of string array (Utf8, Utf8View, LargeUtf8View, Dictionary(...), etc)
   
   If this ticket is just about making it easier to write slt tests, I think the `string` tests might be enough
   
   However, at least part of this ticket seems to be suggesting changing what Arrow DataType is used for `varchar` -- if that is what you are proposing then I think the `string` slt is not enough 🤔
