https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31073 Kyle M Hall <kyle@bywatersolutions.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kyle@bywatersolutions.com --- Comment #3 from Kyle M Hall <kyle@bywatersolutions.com> --- The problem code is in C4::XISBN: # loop through each ISBN and scope to the local collection for my $response_data( @{ $response->{ isbn } } ) { next if $unique_xisbns->{ $response_data->{content} }; $unique_xisbns->{ $response_data->{content} }++; my $xbiblio= _get_biblio_from_xisbn($response_data->{content}); next unless $xbiblio; push @xisbns, $xbiblio if $xbiblio && $xbiblio->{biblionumber} ne $biblionumber; } Basically, we run a search for each returned isbn to see if it's in our catalog. Some of these titles have hundreds of ISBNs, especially for the classics. For example, the brothers karamazov has nearly 500 isbns in ThingISBN. The solution could be A) convert these hundereds of small queries into one or more big queries and/or B) move the this to the front end where we get the ThingISBN data via javascript then search our own catalog via the rest api -- You are receiving this mail because: You are watching all bug changes.
