some thoughts on the export tab
yes, it's wonderful and it helps starving babies in africa
but do we really have the resources to serve arbitrary data to people?
I've noticed the tile server taking a nose dive (and api calls
actuall) in speed recently and I thought it was the bandwidth from
various locations. But, it may be that the export magic is partially
happening on that box?
Anecdotally I've heard of a few people hammering the export tab for
data. This is exactly why we don't ship WMS and WFS. It's why tiles
are good and limited bounding box requests from the map call are good.
We will never satisfy the arbitrary data requests for the export tab
or WMS etc as there will always be more wanted. Adding an arbitrary
output format just adds another arbitrary format on to it, making it
more computationally intensive.
Really, the existing boxes should be throwing out as many tiles and
API calls as possible. We should buy a new box for export and it
shouldn't be a priority in terms of memory, disk, uptime etc.
