Greetings Gentlemen, Chuck, and Davids, I am exploring how to limit the number of columns queried and used in for a listing in D2W. My experiment uses ERModernLook, and has a the SDSS DR1 data set. Several of the tables have an annoyingly large number of columns (641 to be precise) and a large number of rows (770k of them). If the JVM is tweaked to 3GB of memory, ERModernLook can return a list from a blank query (taking nearly 2.5GB memory footprint). I have a few more tables with just about as a bad of a scheme and size arrangement. It would be nice to use this data set to measure just how much abuse D2W can handle.
A couple things would be handy for this experiment. 1. How do I use ERDQueryDataSourceDelegateInterface? It appears that the interface requires implementation of the queryDataSource and qualifierFromSender methods. 2. Is there a way to specify different query data sources for different tasks for the same entity (list versus inspect)? 3. How do I get more run time logging from the WO application itself? I thought Shark could do something with the JVM. Can it measure the memory foot print over time? If so, how? Thank you, Dan Beatty, M.S. CS (B.S.
