New to Raven DB - ID's increment by 32, is this normal?

[ghandicap]

I just got RavenDB up and running and I'm successfully saving and retrieving records. I noticed that my record Id's all increment by 32, is this normal behaviour for the database?

Example:

• Cars/1
• Cars/33
  
• Cars/65
  
• Cars/97
  
• Cars/129
  
• And so on...

If you see this jump every time, it seems you're not managing the session properly.

You should not be calling SaveChanges on every single Store() just at the end.

Given your example if 6 cars with an empty database a single SaveChanges should result in

cars/1

cars/2

cars/3

cars/4

cars/5

cars/6

If you do the operation again, you should see it jump.

Thank you Oren!

So based on this post: http://ayende.com/blog/154337/ravendb-self-optimizing-ids

If I understand correctly, If I happen to create more than 32 documents for a transaction, RavenDB will simply request a second batch of IDs? And then learn to get bigger batches over time if I happen to do this operation often?

If so, Thats very cool!
