[xquery-talk] Count of Distinct elements performance problem

[Kusunam, Srinivas]

Sorry I forgot to mention the environment.

 

XQuery Engine:   Data Direct

OS:                  Linux 32 bit

JVM:                  1.5.0

 

Are there any other products in the market which can handle this load? 

 

I tried with Saxon and it goes out of memory for even 1GB file on 32 bit
machine (1.8GB memory limitation) which does make sense as you said
previously Saxon needs a memory at least 3 times the size of input XML.

 

Thanks,

Srinivas

Did you tell us what product you are using?

 

As I mentioned, the recursive code depends heavily on optimization in
the processor - as indeed does everything, with the kind of data volumes
you are dealing with.
