Hi Erik, sorry I had to miss your recent
visit to Toronto... I have to miss CASCON as well.

This is a good requirement. Please  work
with Marius to get a bugzilla feature request into the system so we can
track and prioritize this. Marius is the owner/commiter of our EMF models
and loaders.

Thanks for your time.

Subject	[hyades-dev] Request for feature: streaming support for trace data

I'm working on analysing profiling data for COTS based
systems. I did a
presentation of my work at CAS two weeks ago and I'll be presenting a paper
at CASCON on that topic. I'm currently looking at implementing my analysis
methods on top of Hyades.

Problem: manipulating profiling trace data in Hyades requires the trace
to
be loaded in memory. Consequently large traces cause the host to run quickly
out of memory and paging causes very slow response time.

Feature request: some kind of streaming support on the TRC model to
transparently load and save to disk TRC objects. Ideally a database backend
would be nice but it could be probably implemented at the collection level
too. I've been in contact with R. Duggan who told me that there has been
work in this direction.

I'd be willing to contribute and help for that feature.
