Greg, Absolutely, perhaps I'm tainted by write-heavy systems and perhaps I'm just failing to see the overhead we're talking about. Perhaps I overlooked it, but the paper didn't mention performance for small writes and potentially multiple nodespanning transactions. I'm inclined to believe that some sort of immutable records storage would simlify the semantics (analytic queries are IMHO very seldom demanding real-time snapshots) > > > As for my little project, i think it's a perfect match for DSLs that cover > analytic set ups like i see in biology and computational finance. > > Best wishes, > > --greg > > On Wed, Jul 22, 2009 at 12:03 PM, Viktor Klang <[email protected]>wrote: > >> >> >> On Wed, Jul 22, 2009 at 8:05 PM, Alex Cruise <[email protected]> wrote: >> >>> >>> Viktor Klang wrote: >>> > Read it earlier today. >>> > >>> > It's quite interesting, transcoding SQL to MapReduce jobs that uses >>> > RDBMes as datasources >>> > >>> > I see this really useful for analytical querying over huge datasets, >>> > but I wouldn't imagine it as an option as persistence-store for >>> > domain/business objects. >>> Definitely not yet, but their approach *should* be amenable to >>> read-mostly/some-writes use cases in that it tries to discover which >>> node(s) hold the data that will be affected by analyzing the SQL AST; >>> distributed transactions are awful but at least they can be contained to >>> a subset of DBMS nodes. >> >> >> I'm also interested in the possibility to use other/develop new query >> languages that can use the same mechanics. >> >> Gregory: Do you see Project Stockholm benefitting from this? >> >> >>> >>> >>> -0xe1a >>> >>> >>> >> >> >> -- >> Viktor Klang >> >> Rogue Scala-head >> >> Twttr: viktorklang >> >> >> > > > -- > L.G.
