Bug ID: 16855
Summary: Poor performance due to high overhead of SQL call in
export.pl
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5 - low
Component: Tools
Assignee: [email protected]

Export.pl uses Koha::Biblioitems->search() to retrieve biblionumbers for the
export process.
The SQL code generated by this does a full dump of the the biblioitems table
including the marcxml for each record.
This table can be quite large and on smaller servers can actually cause debian
to fire oom-killer on the process.
As the results of the search are only used to push biblionumbers into an array
it might make better sense to do a direct SQL query and not retrieve the
marcxml column
