Bad performance of /camp endpoint

[usu]

Code branches

See linked pull requests for timing measurements.

• Baseline
  Implemented:
  • Add some missing indexes + add performance measurement via frontend
• Option 1
  Implemented:
  • rootContentNode is always a ColumnLayout
  • Workaround for ContentNode->owner
  • no eager loading for /camps endpoint

Notes on identified performance problems

Doctrine lazy loading issues

• AbstractContentNodeOwner->rootContentNode (Problem: *ToOne to abstract entity)

  • Implemented in option1: Fixed to ColumnLayout
  • Alternative: Introduce special RootContentNode
  • Alternative: Many rootContentNodes (OneToMany)

• ContentNode ->owner (Problem: OneToOne inversed not lazy loadable)

  • Implemented in option1: Workaround ManyToOne misused for OneToOne
  • Alternative: Remove owner completely and store relation to camp (relation to camp is needed for security check on /content_nodes endpoint)
  • Alternative: Remove owner completely. Use another interface (e.g. BelongsToContentNode interface) for security voting.

Eager loading issues

• Queries generated by eager loading can get really huge for entities with many OneToMany relations (i.e. query with 2800+ rows for a single camp)
• Eager loading cannot be disabled globally (method documented in https://api-platform.com/docs/core/performance/#force-eager didn't work)
• EagerLoadingExtension stops recursion if $propertyMetadata->isReadableLink() is not true. However, in many cases we set readableLink not on the property itself but on a getter (e.g. Camp->getEmbeddedPeriods()). In this case, data is not eager loaded although the data will be embedded later in the response.

Normalization

• RelatedCollectionLinkNormalizer fully normalizes the object before replacing the links. In many cases we load many child entities which are not needed, because we replace them later with a single link (especially for collections, where the child entities are normally not embedded).

ContentNode endpoint

The ContentNode endpoint is sill the slowest, as individual content is loaded via separate queries after the ContentNode collection is loaded. Mainly:

• MaterialNode->getMaterialItems()
• Storyboard->getSections()
• MultiSelect->getOptions()

Potential solutions:

• Manually eager load all possible data (not sure how; maybe in repository?)
• Teach EagerLoadingExtension to understand subclasses
• Refactor ContentNode (see separate proposal in Proposal for ContentNode refactor #2633)

Initial issue description

Loading a single camp from the API takes much longer than it should (one of the slowest endpoints). There are a lot of SQL request triggered in the backend. Not entirely sure why. Assuming it's connected to eager loading and somehow doctrine tries to manually load the rootContentNode of each category and each activity of the camp (even when no such data is embedded).

Couldn't really figure out how to avoid.

@carlobeltrame is working on this i think

[usu]

If I understood correctly, @carlobeltrame was working on the idea on how to specify serialization groups via request, which controls what data will be embedded in the response. However, the above behavior I observed even when no data was embedded.

First indication seems to be that this something Doctrine related and not API-platform related, but I might be wrong on this.

[carlobeltrame]

That is exactly right. Since I noticed that fixes like #2571 are not possible everywhere (e.g. the picasso can only load a list of schedule entries but not all their content nodes via a simple filter, so we either have to embed the content nodes or we have an n+1 problem), I started working on user-specified serialization groups.

[usu]

Trying to further pinpoint on this, I believe the issue comes form the OnetoOne-Relation between AbstractContentNodeOwner->rootContentNode and ContentNode->owner.

The additional queries are triggered by the same code line here:
doctrine/orm#2239 (comment)

It's documented by Doctrine as a performance issue (see chapter "Performance impact" on below link):
https://www.doctrine-project.org/projects/doctrine-orm/en/2.11/reference/inheritance-mapping.html#class-table-inheritance

[carlobeltrame]

Wow. This means that for performance it would actually be better if we eliminated the static, non-editable column layout at the root of the content node tree, and changed the relation activity <-> contentNode to a oneToMany relation. But that might make the logic more complicated in different places instead, not sure.

[usu]

If the target-entity of a many-to-one or one-to-one association is a CTI entity, it is preferable for performance reasons that it be a leaf entity in the inheritance hierarchy, (ie. have no subclasses).

I struggle a bit to understand why a many-to-one & one-to-one relation has this impact, but a one-to-many relation should be ok. Maybe a one-to-one could also work by changing the owning side. Although in our case both AbstractContentNodeOwner and ContentNode contain subclasses, so we might face the issue anyway one way or the other.

Probably worth experimenting a bit to see what works and also if it really makes a change (or whether the performance impact comes from somewhere else). Options I see:

1. One-to-one but changing the owning side (but owner property needs to be nullable)
2. Option 1 + getting rid of AbstractContentNodeOwner by mapping ownership via two different properties activity & category instead of owner only.
3. One-to-many from AbstractContentNodeOwner->rootContentNodes to ContentNode->owner
4. Mapping AbstractContentNodeOwner->rootContentNode directly to ColumnLayout (leaf node) or even to a new specific RootContentNode subclass

[usu]

Other options:

• Try disable eager loading (https://api-platform.com/docs/core/performance/#force-eager)

[usu]

Trying to dig a bit further down the rabbit hole.

As to my current understanding, the following examples could lead to additional SQL-queries and therefore to a potential performance problem.

Bidirectional OneToOne (from inverse side; no inheritance)

Even without inheritance, bidirectional OneToOne-relations cannot be lazy loaded from the inverse side (the side without foreign-key).
Why: Without querying the relation, doctrine doesn't know if the other side exists (Proxy needed) or not (null value). So it needs to load the owning side as well. The additional query could be avoided by joining (eager loading), which should have minimal performance impact.
api-platform/core#2866
doctrine/orm#4389 (comment)
doctrine/orm#4389 (comment)

OneToOne (owning side) and ManyToOne, if target entity is an abstract class (inheritance)

This case is similar to the one above. In this case, doctrine has a foreign-key, but it doesn't know the class type of the target entity without loading it. So doctrine knows whether it should create a Proxy or not, however it doesn't know which type of Proxy to create.
doctrine/orm#4389 (comment)

OneToMany

OneToMany is never a problem (both with or without inheritance), because doctrine always creates an empty collection, independent of whether there are any items in the collection (and also which type of entities). The collection serves as the proxy in this case.

Workarounds & solutions

Community discussed workarounds/solutions (other than the ones already discussed above).

For the OneToOne-relation:

• My naive solution to fix this within doctrine would have been to store entity_type (and FK for OneToOne) on both sides of the relation. Haven't seen any concrete issue/PR on this though. But it also seems doctrine is rather reluctant change anything in this direction.
• Try to eager load (join) as much as possible to avoid additional queries
• Misuse OneToMany as OneToOne (DDC-357: Lazy-loading in OneToOne-bidirectional associations not working for inverse side doctrine/orm#4389 (comment))

For the ContentNode-Tree:

• Use JSON for trees of abstract entities (Add new SqlWalker Hint to manually specify inherited sub-classes to outer join doctrine/orm#8178 (comment))
• Use class-table-inheritance to build the node tree (or even non-abstract entities?) and store additional data in a JSON column (also Add new SqlWalker Hint to manually specify inherited sub-classes to outer join doctrine/orm#8178 (comment))

[carlobeltrame]

For the content node tree, maybe we could also use nested set instead of parent relations. This is a much more efficient way of storing tree data structures in relational databases, once the initial boilerplate code is written to transform e.g. ->children calls into the correct SQL. There is already an implementation of this in doctrine extensions nestedset. Not 100% sure, but that might help with the eager loading problems, since the relations are not normal doctrine relations anymore.

N.B. in hitobito, the group hierarchy is also implemented using a nested set implementation from an external package, and there it works great.
