Re: Insert and delete row
The iterator that processes delete markers is setup by the system and
you can not get below it.  Delete markers are only dropped on a full
major compaction.  So you could force a major compaction of the table,
or a range of the table.   Or you can insert with a timestamp greater
than the delete marker.

It makes sense because the delete really just adds a delete row that tells Accumulo to ignore any row that is equal to it. Is there a way to bypass this? Where I could set up my own iterator to decide if a row should be deleted or not? (not sure how I would decide yet, but just seeing if it is possible to bypass the delete logic as is)
