Subject [jira] Created: (HBASE-1481) Add fast row key only scanning
Date Thu, 04 Jun 2009 19:29:07 GMT
Add fast row key only scanning

                 Key: HBASE-1481
                 URL: https://issues.apache.org/jira/browse/HBASE-1481
             Project: Hadoop HBase
          Issue Type: Improvement
    Affects Versions: 0.19.3
            Reporter: Lars George
            Priority: Minor
             Fix For: 0.20.0, 0.21.0

Instead of requiring a user to set up a scanner with any column and scan the table to gather
all row keys while ignoring the column value we should have a fast and lightweight scanner
that for example takes a "null" for the column list and then simply returns only the matching
keys of all non-empty or deleted rows. Filters should still be applicable.
