For a large database table that has millions of records(rows), how is the memory managed from backend to <h:dataTable>? all the millions of records are in memory? That would crash the system. Is the collection( returned from database layer) actually not filled with data until they are requested ? Thanks. Dave

implementing a custom datamodel might be your friend in this case...
unless you use plain jdbc, afair there was a jdbc datamodel in the
core classes.
