> The Spark2 connector handled lowercase and mixed case column names correctly in DataFrame definitions.
> Spark3 only does case-insensitive column resolving, and even _spark.sql.caseSensitive_  doesn't seem to do anything, neither backquouting.
> Again, this is not something that can likely be fixes from the Phoenix side without changes in Spark, and this ticket is mainy for documenting this regression.
