MISC ITEMS THAT CAME UP
todo: large number of units = timeout on list view
this query:
this query painfully slow and times out with huge data:
SELECT COUNT(*) from aunit left outer join acustomer on (aunit.customerid=acustomer.id) left outer join aunit as aparentunit on (aunit.parentunitid=aunit.id) left outer join aunitmodel on (aunit.unitmodelid=aunitmodel.id) left outer join avendor on (aunit.purchasedfromvendorid=avendor.id) left outer join aunit as areplacedbyunit on (aunit.replacedbyunitid=aunit.id)
Figure it out
This query:
SELECT COUNT(*) from aunit
left outer join acustomer on (aunit.customerid=acustomer.id)
left outer join aunit as aparentunit on (aunit.parentunitid=aunit.id and aunit.parentunitid<>null)
left outer join aunitmodel on (aunit.unitmodelid=aunitmodel.id)
left outer join avendor on (aunit.purchasedfromvendorid=avendor.id)
left outer join aunit as areplacedbyunit on (aunit.replacedbyunitid=aunit.id and aunit.replacedbyunitid<>null)
Super fast no timeout
todo: Join filters make a huge difference in speed of datalist queries (and anything else when working with huge data)
check into all datalist and picklist queries with joins at the server and if the joined table is optional (foreign key null possibility) then add a join condition
todo: Notification at server has NotifyDeliveryLog object unused and no UI at from for it either
it's supposed to keep a set queue of the past 90 days of deliveries for troubleshooting like in v7,
