Hi, We were studying on the parallel execution of MonetDB and memory usage of MonetDB. 1. If two queries access the same table in parallel, is the table loaded twice into memory or its loaded only once? 2. Is the hot dataset from a column of a query cached in memory, so that any further queries accessing that column may use it? 3. Are the interim results of a query cached in memory for further queries? Thanks & Regards, Vijayakrishna.P. Mobile : (+91) 9500402305.
