Description Scott Rosenbaum

2008-03-22 13:53:48 EDT

At EclipseCon I spoke with a number of users who were interested in using BIRT as an embedded reporting solution.  Several of them were concerned with the size of the BIRT Runtime, particularly those who were creating an RCP application which would require a full download.  

Most felt that 35 Meg was too large.  I tried to quiz as to how small was small enough, and I got the inevitable as small as possible.  That said most agreed that a full reporting solution of less than 10 Meg was acceptable.  

I realize that to go from 35 to 10 is going to be difficult, especially since a large portion of that total is attributable to other jars (e.g. com.ibm.icu is nearly 4 meg on its own).  

I guess this is a long term tracking effort to see if we can:

a) reduce the size of the core birt runtimes
b) reduce the size of the birt dependencies
c) eliminate any redundancies
d) provide better documentation in terms of what is needed and what is optional

As a simple for instance, the com.ibm.icu is in both the lib directory as well as the plugins directory.  It seems like there should be a way to eliminate the dual entry.

We can not remove the jars in the lib directory because they are for the app server's class loader, while the libs in the plugin folder is for the OSGi class loader.

please reopen if there is suggestion on how to reduce the size.

Also, It woul dbe interesting to know what kind of hardware the user is targeting.   Is disk space an issue or is it memory footpint as issue.
