There doesn't seem to be an FR in data.table related to this though.<br>
<br>
int64 indeed looks very useful. It seems to do it internally using 2<br>
regular int vectors, and that causes data.table an issue because it<br>
doesn't currently accept types that are not atomic (such as POSIXlt).<br>
That could be the FR then: allowing multi-column types (for which int64<br>
is worth it, but not POSIXlt)?<br><br>
I don't know how int64 compares to those, or if they use multi-columns<br>
internally or not, or what.<br>

Btw, does anyone know what sponsorship by Google actually means in<br>
practice?</blockquote><div><br></div><div>I feel that the biggest benefit is advertising and marketing. Not all great work get enough notice. Good channel to spread out awesome work is important, too. </div><div><br></div>
