[keycloak-dev] Concurrency & EventsListener SPI

[Poiffaut Romain]

Hi,

I am writing a provider for eventsListener SPI.
Could anyone tell me if the provider and its provider factory need to be thread safe ?
With more details, I need to store some events. To do so, I am using a collection created by the factory and a reference to this collection is passed to the constructor to update it.
Does my collection needs to be concurrency-safe or is it not needed?

Best regards,
Romain
