Hi all,
I'm trying to convert a Perl script from RDBMS to CouchDB and thus I
turned to Net::CouchDb (btw, why CouchDb and not CouchDB?). It doesn't
currently seem to have an easy interface for reading views, so you
have to use the call() function which does a plain REST call.
The most difficult part to find out was how to handle the results from
a call, since they're a pointer to a hash and the rows member is a
pointer to an array of hashes. It would be nice if that could be
abstracted away, for example behind an iterator interface.
Anyway, this is what I have right now:
my $answer = $dbh->call('GET','_view/images/all?
include_docs=true');
if ($answer) {
%images = ();
for my $i (@{$answer->{rows}}) {
$images{$i->{id}} = $i->{doc};
}
}
Is this currently the best way to do it?
The images/all view is a simple
function(doc) { doc.imgvmxpath && doc.imgname && emit(null, null); }
which selects all documents that have those 2 keys in them.
I thought that emitting (null,null) and instead using the include_docs
option would keep the size of the view results to a minimum.
Is that thinking correct? Does this incur overhead in different ways?
Thanks,
Wout.
