How to implement batch fetching with Fluent NHibernate when working with Oracle?

Question

I've tried using Future feature with Oracle but NHibernate does not support it.

How could I use it with Fluent NHibernate? how should it be configured?

I tried to explain you, that BatchSize(25) in your mapping (see stackoverflow.com/questions/20986026) would do that job. What exactly is not working? I mean your prev question stackoverflow.com/questions/20970680 — Radim Köhler

It's the first time I've written this question, and the link you sent is not my question so a coincidence if the timing looks near. — The Light

Your question: How to Eager Load Associations without duplication in NHibernate? (the second link in my comment stackoverflow.com/questions/20970680). The first link I've sent -- it is the answer. use BatchSize(25) as I've already told you... — Radim Köhler

To give you the answer how to use batching with fluent:

1) on the colleciton

HasMany<MyEntity>(x => x.Entities)
  .BatchSize(100);

2) on a class level

public MyEntityMap()
{
    Id(x => x....
    ...
    BatchSize(100);
