This might be a dumb question since I have not yet fully understood how Cognos BI works.
Also, I tried posting this on Stack Exchange, in vain (error with putting tags).

My question is - Can Apache Hadoop be used to make Cognos BI work faster ?
Or is Cognos doing the same thing which Hadoop does (MapReduce functionality) ?

The place where I have started working, uses the Cognos BI suite on top of Sybase IQ (the content store). Apache Tomcat is the web server. What happens sometimes is that Cognos takes a lot of time(almost dies) to generate reports if the data set is large.

So can Apache Hadoop help Cognos perform better by fitting somewhere between Cognos and Sybase ? Or is report optimization the only way out in this case ?

Thanks Guys.
