I'm curious about the behavior I'm seeing. I have a directory with about 300
XML files total 3GB.
Each xml file is a few k to a 100M like
<logfile host="hostname" ...>
<log ... />
lots o logs
</logfile>
I have a fragment rule setup on <log>
This query returns fairly quickly (expected)
fn:distinct-values( xdmp:directory("/logs/","infinity")/logfile/@host )
This query gives me an expanded tree cache full error
declare variable $all_logs := xdmp:directory("/logs/","infinity");
fn:distinct-values( $all_logs/logfile/@host )
This is not what I'd expect. I was under the impression that the documents
wouldn't be pre-loaded just by declaring a variable holding a sequence of
documents ... that it would lazy-eval as needed.
So I was expecting the 2 statements to perform similarly.
Obviously I'm wrong. Is this as expected ?
