Christopher Tubbs updated ACCUMULO-501:
---------------------------------------
Fix Version/s: (was: 1.5.0)
> RFile should store the key count in metadata
> --------------------------------------------
>
> Key: ACCUMULO-501
> URL: https://issues.apache.org/jira/browse/ACCUMULO-501
> Project: Accumulo
> Issue Type: Improvement
> Reporter: Eric Newton

>
> BulkImport estimates the number of keys in a file to be zero. We store the
> largest and smallest key in metadata, I think we can afford to store the key
> count use it to provide an estimate when we load it into the tablet. Perhaps
> if we know the start key is "a" and the end key is "z" and the tablets range
> is "a->m" we can just estimate 50% of the key count.
> When a bulk file fits completely in a range, the key count estimate will be
> accurate.
