5.  def canWrite(tableName: String, write: DataType, read: DataType, byName: Boolean, resolver: Resolver, context: String, storeAssignmentPolicy: internal.SQLConf.StoreAssignmentPolicy.Value, addError: (String) ⇒ Unit): Boolean

   Returns true if the write data type can be read using the read data type.

   Returns true if the write data type can be read using the read data type.

   The write type is compatible with the read type if: - Both types are arrays, the array element types are compatible, and element nullability is compatible (read allows nulls or write does not contain nulls). - Both types are maps and the map key and value types are compatible, and value nullability is compatible (read allows nulls or write does not contain nulls). - Both types are structs and have the same number of fields. The type and nullability of each field from read/write is compatible. If byName is true, the name of each field from read/write needs to be the same. - Both types are atomic and the write type can be safely cast to the read type.

   Extra fields in write-side structs are not allowed to avoid accidentally writing data that the read schema will not read, and to ensure map key equality is not changed when data is read.

   write

   a write-side data type to validate against the read type

   read

   a read-side data type

   returns

   true if data written with the write type can be read using the read type
