17. Paris MAR-2002 DataGrid WP3 Problems with R-GMA: 1. Sensor data MUST be pushed to Producer servlet e.g.for debugging, queries may focus on small section of logfiles, yet complete multi-GB logfiles must be move to Producer servlet 2. Each query MUST instantiate new objects & connections e.g. when debugging, have constant interaction with same producer, yet each query requires fresh instantiation of Consumer servlet + http connections

18.
