RE: Delete All Data In Table

[Bob.Thorman]

When/if you do the speed comparison would you mind sharing the results?

Josh,

Thanks for the tip!  I was able to delete the data and keep the splits using 
the following code:

    String dataTableName = "dataTable";
    String iteratorName = "devNull";
    
    if(conn.tableOperations().exists(dataTableName)) 
    {
      IteratorSetting setting = new IteratorSetting(25, iteratorName, 
DevNull.class);

      EnumSet<IteratorScope> scopes = EnumSet.noneOf(IteratorScope.class);
      scopes.add(IteratorScope.minc);
      scopes.add(IteratorScope.majc);
      scopes.add(IteratorScope.scan);

      conn.tableOperations().attachIterator(dataTableName, setting, scopes);
      
      conn.tableOperations().compact(dataTableName, null, null, true, true);

      conn.tableOperations().removeIterator(dataTableName, iteratorName, 
scopes); 
    }

I haven't tested out the speed yet to see how it compares to BatchDeleter but 
it definitely works.  Thanks for your help!
