Description

The current RocksDB scanner command allows only a simple length parameter to limit the number of records to scan in a specific col family. In the case of a huge table like keyTable or containers, while we are looking for a specific entry, the search is needlessly large and explorative (since we do not know the 'index' of the key)

A startKey param would be useful.

 ozone debug ldb --db=<> scan --column_family=<> --length=<> --startKey=<>
