Equivalent of NHibernate batch_fetch_style property #483
-
|
For my .HasMany() relationships I'm using something like .BatchSize(16) to alleviate N + 1 performance issues. This works well, but a well-known problem is that it can significantly increase memory usage of BatchEntityLoader. There is a parameter in NHibernate called hibernate.batch_fetch_style that lets you trade off a bit of performance for lower memory usage. I would like to try the Dynamic setting. How do I access this parameter in Fluent NHibernate? |

This parameter is not ported to NHibernate, you are referring to Hibernate documentation. So you cannot configure it with Fluent, since it does not exist in NHibernate. |

Ah, that makes more sense. Thank you. |

The memory usage issue is known, see nhibernate/nhibernate-core#1316. Porting the Hibernate setting is one way to solve it, as already commented in the issue. It awaits someone interested in contributing a fix.
