Performance problem with notifications

[Nelrann]

We use Timelinebundle and we have performance problem with notifications.

When notifications was deleted with UreadManager, mongo increases much value locked db (mongostat).

You know where this problem come from ?

Hi,

I don't know, it uses this method https://github.com/stephpy/TimelineBundle/blob/master/Driver/ODM/TimelineManager.php#L81-L95 but it'm not confortable with mongo. Try to do the same thing (or with other ways) with doctrine and see if it could fix the problem. If you find a solution, we could implement it on ODM/TimelineManager.

@stephpy I solved the problem by adding indexes

Action 
@ODM\Indexes({
 @ODM\Index(keys={"subject"="asc", "statusCurrent" = "asc"}),
 @ODM\Index(keys={"subject"="asc", "statusWanted" = "asc"}),
 @ODM\Index(keys={"subject"="asc", "verb" = "asc", "createdAt" = "asc"})
})

Timeline
@ODM\Index(keys={"context"="asc", "subject"="asc", "type"="asc", "createdAt"="asc"})

Component
 @ODM\Index(keys={"model"="asc", "identifier"="asc"})
 @ODM\UniqueIndex(keys={"hash"="asc"})

I think we can add it directly in the bundle

@Toinouu greats !!!

Can you make a PR with theses changes please ?

[Nelrann]

@stephpy yes

[stephpy]

Mapping in this bundle is defined in XML format. I made the PR here:

#130

Can you confirm @Toinouu it's OK please ?

I followed https://raw.githubusercontent.com/doctrine/mongodb-odm/master/doctrine-mongo-mapping.xsd and this doc but i didn't test it on my environment.

@stephpy I think you changed wrong file Component.orm.xml => Component.mongodb.xml
but your mapping is OK +1

[stephpy]

OMG, you're right :s

[stephpy]

That's fixed & merged.
