#1623: implicit save() of associations vs. performance
---------------------------------------+------------------------------------
Reporter: floriank | Owner: jwage
Type: enhancement | Status: new
Priority: minor | Milestone: Unknown
Component: Attributes | Version: 1.1-DEV
Keywords: implicit save performance | Has_test: 1
Mystatus: Pending Core Response | Has_patch: 1
---------------------------------------+------------------------------------
Since my application uses some deep nested sets the performance of saving
an object (with validation) takes extremely long. This is because Doctrine
saves (and validates) the record to be saved, its relations, the relations
of the relations, and so on. As i only change the properties of the main-
object, one-to-one, one-to-many and first-level many-to-many relations i
decided to change UnitOfWork->saveAssociations() to only call save() if
one of its records is modified.
This gives me a huge performance-boost, but at cost of the ability to save
dirty relations that are deeper than one level in hierarchy. I attached
testcase plus patch: Maybe someone likes to check and discuss this?
Greets,
