> Don't use zip and scala collection methods to avoid garbage collection
> {code}
> val partitionPath = partitionColumns.zip(row.toSeq).map { case (col, rawValue) =>
> val string = if (rawValue == null) null else String.valueOf(rawValue)
> val valueString = if (string == null || string.isEmpty) {
> defaultPartitionName
> } else {
> PartitioningUtils.escapePathName(string)
> }
> s"/$col=$valueString"
> }.mkString.stripPrefix(Path.SEPARATOR)
> {code}
> We can probably use catalyst expressions themselves to construct the path, and then we can leverage code generation to do this.
