I noticed a new headless branch that aims to replace BATs with COLs.<br>Could you give me more information on COLs?<br>Is what you are trying to achieve faster queries, less memory usage, or other advantages?<br>Assuming that this is the new direction for MonetDB, do you expect that it will be merged with the Hg default tip for the next release after March 2011?<br>
Thanks.<br><br>David Suh<br><br>
