SymfonyOnline June 2023 – Teaching Doctrine to be Lazy

The upcoming international conference, SymfonyOnline June 2023, will take place in less than 2 months on June 15 – 16. We have already announced some speakers and talks. Click here to read more details.

It is our great pleasure to announce that our next speaker to join the team is…

Kevin Bond (@zenstruck), Open Source, PHP, Symfony Developer / Symfony Core Team, will present „Teaching Doctrine to be Lazy“:

„Doctrine object managers are greedy: when you query for a set of objects, they love to load everything, all at once. That’s normally great – but what if you’re working with large data sets, where you might load 10’s of thousands of objects?

In this talk, we’ll teach Doctrine how to be lazy by demonstrating how to efficiently query and work with large data sets. We’ll cover: Lazy queries, Lazy relationships, Profiling and reducing object „hydrations“, Efficient batch processing, An alternate “lazy-by-default” repository pattern“.
