Hi Esteban,

yes, Mongo is not very communicative ;-)

I replaced OID>>nextOID ��with my own RKAOIDGenerator��

nextOID
^self value: (RKAOIDGenerator getNextOID)

instead of

nextOID
^self value: (UUIDGenerator default makeSeed)


RKAOIDGenerator uses Time>>primMillisecondClock at startup and adds +1 each time I getNextOID as you suggested.

This works fine. It seems to be much much much faster than the existing solution.

[4000 timesRepeat: [UUIDGenerator default makeSeed]] timeToRun �� ��==>> 5817
[4000 timesRepeat: [RKAOIDGenerator getNextOID]] timeToRun �� �� ==> 1 (!!)

Perhaps a solution like this would be a better solution for all because it is faster and��guarantees��unique IDs?

Hi,

One idea (not sure if it will work)

You can take

Time primUTCMicrosecondsClock

when system start, then increase it sequentially.
most probably that will ensure uniqueness while providing fast ids.

but of course, that depends, you need to check in your system.

I'm thinking on provide different ID generators for Voyage, and let people plug what is more convenient for them.

(all of this happens because, unlike other db drivers, mongo does not answer the inserted id :( )
