> When running index tool with index table as source, it splits a page into
> tasks when the page size is greater than the configured task size (default
> 2048) and runs each task in parallel. Each task is assigned a set of data row
> keys but the index mutation map is not split according to the data row keys
> assigned to a particular task. As a result, the tool reports wrong results
> because the index mutation map is per page but the set of data row keys is
> per task.
