Re: Java client 1.1.4 and headOnly() in domain buckets

2015-05-13 Thread Alex Moore 
Hey Daniel,

It appears that the domain buckets api does not support headOnly().  That
api was written to be a higher-level abstraction around a common usage, so
it abstracted that idea of head vs object data away.  If you need that
support, I would use the regular bucket methods instead.

Thanks,
Alex

Hi Alex

 It appears that the domain buckets api does not support headOnly().  That
 api was written to be a higher-level abstraction around a common usage,
 so
 it abstracted that idea of head vs object data away.  

I think it may be quite useful functionality anyway, to check the existence
of a key.
This is what I'm using it for to avoid loading big objects from leveldb.
Can you confirm if that operation does not read data from the backend or is
there any other better way to check existence of the key?

 If you need that support, I would use the regular bucket methods instead.

That's what I ended up doing although it's not convenient to have two bucket
instances configured differently to access data in one way or another i.e.
writing through DomainBucket, checking keys through regular bucket.

Hi Daniel, do you have reasons not to upgrade to the latest driver. I know
the semantics have changed somewhat. Are you running a fork of the client?
