I have a project involving multi-gigabyte datasets of line plot data. With your 0.4 release, will it be possible to show down-sampled subsets of these plots, with the ability to pan/zoom around and get more data on demand without having it all held in memory?

Well, we'll be able to do that without sending the data to the client, not sure if our implementation right now will work without loading the data into memory, though long term that is definitely the plan (we will leverage http://blaze.pydata.org/)
If you want to discuss further, please email [email protected]

The Python version of Abstract Rendering currently would load it all into memory. The Java version is based on the same algorithms would not. It routinely handles multi-gigabyte files and lets us know that the core algorithm can scale. We're working on getting the Python implementation to scale as well.
