Has anyone ever succeeded in optimizing those: SELECT ezcontentobject_attribute.*, ezcontentclass_attribute.identifier
as identifier FROM
ezcontentobject_attribute, ezcontentclass_attribute
WHERE
ezcontentclass_attribute.version = '0' AND
ezcontentclass_attribute.id =
ezcontentobject_attribute.contentclassattribute_id AND
( ( ezcontentobject_attribute.version = '3' AND
ezcontentobject_attribute.contentobject_id = '15539' AND
ezcontentobject_attribute.language_code = 'pol-PL' ) OR (
ezcontentobject_attribute.version = '1' AND
ezcontentobject_attribute.contentobject_id = '13743' AND
ezcontentobject_attribute.language_code = 'pol-PL' ) OR (
ezcontentobject_attribute.version = '3' AND
ezcontentobject_attribute.contentobject_id = '15540' AND

Pre loading of content object attributes when you fetch nodes using content 'list' or 'tree' fetch:

Hi Andre, Thanks for quick reply! As far as I understand it correctly, when is switch the default setting off, a number of lightweight direct fetch queries will be used instead of this gigantic "OR compound", right? This should not affect the functionality in any way?
Thanks,
Piotrek

No affect, only change is by default use more smaller faster sql calls instead of one gigantic one when you fetch for instance above 15 nodes.

OK, seems to be working fine. Just to make sure: before you implement a INI-based setting (or whatever) in eZ Publish 4.1.x, if I disable the load_data_map by default in 4.0.x, all my lists will be generated based on small queries, no matter how many items fetched, right? There is no internal limit of 15, right?
Thanks,
Piotrek

Hi,
I have severe troubles with sloooow queries like the one described in this thread. I see that this has been solved in 4.1, but what about eZ 3.8.6?
I am running a huge site with about 100 000 content objects. Fetches like these can take up to several minutes to perform. Does anyone have a clue on how to fix this in eZ 3.8.6?
Best regards,
/Nicklas

Just an update - works fine up till now. I think we will set it as default for all our implementations... By the way - in 4.1 will there be a fetch list count under which eZ Publish will force the old complex approach?
Cheers,
Piotrek
