Subject Re: REPOST: Adding an option to output results to a db? (not csv or xml.)

Agreed. In principle it is possible to tune inserts to high levels (we got
it up to 40k a second) but that was with fairly lightweight data and
involved some tweaking of the db params which is non-standard. 

I guess a better approach might be either to write to a db non synchronously
using a flat file as a buffer or maybe using some sort of mem cache. The
latter would offer the best throughput but with obvious risks.

>What makes you think that Listeners depend on the output format? 

I was thinking in terms of loading results offline. Ideally if results are
written to a db then it should be possible to point a listener at this
source. We'll review the common code on that.

Thanks for your replies; we'll try and spend some more time on this.
