    Description

      There are several filter operations (e.g., filterKeyValue, filterRow, transform, etc.) at the region server side that either exclude KVs from the returned results, or transform the returned KV. We need to provide observers (e.g., preFilterKeyValue and postFilterKeyValue) for these operations in the same way as the observers for other data access operations (e.g., preGet and postGet). This extension is needed to support DOT (e.g., extracting individual fields from the document in the observers before passing them to the related filter operations)
