using external to generate shortid ?
Hi,
For some project I need to generate short ids/name used in database. I
created a quick external to send shortid on each call. External use an
empty doc['shortcode'] which is saved each time the external is called
thend send bac the rev stem b62encoded. I then use the shortid across
documents.

But I wonder if it's enough to be sure 2 doc don't have same short id
for a node. In fact how are handled externals ? Does couchdb open a
process each time external is called or does it reuse it ? Does
couchdb open one external / guest connected to the db ? I would prefer
to store the sort increment in couchdb so I could do backup easyly.
What could be the other way to create a short id ?

So I guess this script should work. Thanks for explanation.

External servers use one process per node. All requests for all
databases pass through the same OS process unless it dies in which
case it's restarted.
