["Harm Sluiman" <nobody@xxxxxxxxxx>]

Hi Boris. Good questions.

Binary log files
Yes we want to add binary support at several levels as soon as we get 1.0.0 out the door.
We need to resolve a few issues like mixed mode agents, and if we want to have predefined binary
structures for common cases, as we did with XML fragments. Once we have ways to source the data
consistently we can make the correct extensions for the loaders, and perhaps some optimized model
structures.

Performance
So far we have not had a significant real life problem with using XML fragments. However you have
hit an important limitation of the current viewers. They assume all of the model to be logically in
memory, which today means it is. We are working with EMF team to address logical vs. physical memory
use cases. You also hit on the pre-load filtering, and that is definitely something we want to work
on soon. At the moment the sample viewer has no filters, and this is clearly a bad limitation. We
are looking at a complete replacement of this viewer.
The only way to work around this is to import partial traces/logs, which is admittedly a pretty lame
answer.

Filtering
We have done a reasonable job for filtering profiling and trace data (other than the scenario you
hit above), but we have done nothing in this area  for logs and need to.

We are open to contribution in any of these areas.;-) Our team has a limited size, and we do think
of some of these user interfaces as "examples" of how to work with the model. The EMF models are a
key integration point.
