* @class vtkPExtractDataArraysOverTime
* @brief parallel version of vtkExtractDataArraysOverTime.
*
* vtkPExtractDataArraysOverTime adds distributed data support to
* vtkExtractDataArraysOverTime.
*
* It combines results from all ranks and produce non-empty result only on rank 0.
*
* @section vtkPExtractDataArraysOverTime-caveats Caveats
*
* This filter's behavior when `ReportStatisticsOnly` is true is buggy and will
* change in the future. When `ReportStatisticsOnly` currently, each rank
* computes separate stats for local data. Consequently, this filter preserves
* each processes results separately (by adding suffix <tt>rank=\<rank num\></tt> to each
* of the block names, as appropriate. In future, we plan to fix this to
* correctly compute stats in parallel for each block.
