https://dl.acm.org/citation.cfm?id=31...This paper <br /><br />https://dl.acm.org/citation.cfm?id=3137659<br /><br />does propose similar techniques to what you propose Mark. It does review different storage options (column-store vs row-store vs log). And the authors do find a much higher benefit for performing analytics using ta column-store. Cool blog!

Is...> A rowid that works across SSTs might be .<br /><br />Is the rowid fixed for a record for the entire lifetime of that record (especially if you want it non-sparse)? If so, then is it still feasible to use sstnumber to generate it because the sstnumber can change as part of compaction?<br /><br /><br />Anonymoushttps://www.blogger.com/profile/06446817552944459333noreply@blogger.com
