Re: Why is row lookup much faster than column lookup

[Dave Brosius]

Given the hashtable nature of cassandra, finding a row is probably 'relatively' 
constant no matter how many columns you have.The smaller the number of columns, 
i suppose the more likely that all the columns will be in one sstable. If 
you've got a ton of columns per row, it is much more likely that these columns 
will be spread out in multple ss tables. Plus, columns are read in chunks, 
depending on yaml settings.   ----- Original Message -----From: "A J"
