-------------------------------------------------------

Yes, it's string type for all elements (For the one use case I have) (i.e. when the element is created it is of the form ("x1", "x2", ...). I have also edited my JIRA with a note to explain the same.

> I have a parquet file with an array column, when I use the function 'REPEATED_COUNT' in select column it works fine, but when used in where clause I get an error: 
> org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema. Errors: Error in expression at index 2. Error: Missing function implementation: [repeated_count(INT-OPTIONAL)]. Full expression: null.. Fragment 1:4 [Error Id: 1a9b034c-949a-4faa-9185-55d40e4851e7 on uswxapcsd043.ussdnve.baml.com:31010] (org.apache.drill.exec.exception.SchemaChangeException) Failure while trying to materialize incoming schema. Errors: Error in expression at index 2. Error: Missing function implementation: [repeated_count(INT-OPTIONAL)]. Full expression: null..
> Note: The query is reading data from a parquet file. This file was generated using a CTAS expression from a CSV file, and the array column was generated using CONVERT_FROM(colName, 'JSON'). The column has the string in the correct format (["x1", "x2"]). Also the count comes out correct when I use the REPEATED_COUNT(arrayCol) in select column, it's just failing in the where clause
