xenuwhat a gem14:22
Dejanlololol, this was during the CA era :)14:37
Dejanshould we post it on the forum?14:39
Dejan:D14:39
Dejanpeople may react differently there ;)14:39
Dejanxenu, may i?14:40
xenuwhy not? :)14:43

Dejanmade a thread on the forum :D14:48
Dejan"Ingres and You"14:48
Dejanlolol14:48
xenuvectorwise totally dominates these benchmarks ;o15:04
Dejanyeah15:07
Dejanproblem is, that benchmark is for sql databases15:08
Dejanit would be interesting to compare nosql databases with vectorwise15:08
Dejanpeople will not use a SQL database for large data nowadays15:09
DarylM1nosql will turn out to be a fad, imho.  It reminds me of the bad old days of network databases.15:09
DejanDarylM1, as much as i hate the hype around the movement, some things are natural - SQL = overhead15:26
Dejanno SQL = no overhead15:26
Dejanbut, then you are on your own :)15:27
DarylM1no sql = no useful feature15:27
DarylM1After working with hibernate and web frameworks, I can see how people get caught up with NoSQL15:27
DarylM1It matches the paradigm in some situations very well.15:27
Dejanit is like in C++ - you use pointers (no SQL) but you are on your own15:27
DarylM1but that is a very myopic viewpoint15:27
Dejanor you use references, and rely on language guarantees15:28
Dejanboth have use15:28
Dejanand technical person must know about them to be able to make good decisions when to use which one :)15:28
xenubut the question is - are we talking about nosql databases as in "relational databases without sql" or non-relational databases15:32
xenuthe latter are whole different class of databases15:34
xenuwhich can't be compared imho15:35

Dejanthe whole no-sql movement has many hybrids, person needs to know details in order to know if it will be good for the job or not15:45
Vroomfondleone of our managers loves to drop it into conversation15:51
Vroomfondlethe trouble is, it's difficult to immediately articulate the many reason *why* nosql is probably a bad fit for our heavily-relational internal business apps15:51
Dejanboth worlds have people who misunderstand fundamental concepts of the other :)15:58
DejannoSQL guys think in SQL you have limited number of tables15:58
Dejanwell, it is a recommended way of doing things in SQL, but it is not the case15:58
Dejanthere is no doubt that some noSQL databases scale muuuuch better and much easier than any other SQL database16:00
Dejancassandra for an example16:00
DarylM1scale well for what problems?16:07
Dejanthat is actually the most important question :) if architect knows upfront what kind of problem are they going to deal with, and why kind of data queries are they going to have, they can opt for noSQL16:12
Dejanhowever, it is a rare case...16:13
