Brian,
Where I got lost was the fact that I was using custom Converter and I did
not do anything with vclock passed into fromDomain().
That was undetected because at the same time I wasn't using withoutFetch,
which I believe is the only moment where missing @RiakVClock annotation
can be detected. Normally when JSONConverter is used missing @RiakVClock
would also be detected.
Could you confirm?
Few additional, related questions:
- if I use byte[] or VClock field and use withoutFetch() what is default
value it should be set to (since it will be extracted via StoreObject)?
- if I want to avoid overwriting deleted keys, I guess I need to set
returnDeletedVClock as below,
DomainBucketBuilder<Custom> builder = DomainBucket.builder(bucket,
Custom.class)
builder.returnDeletedVClock(true);
and then check isDeleted on sibblings and use ConditionalStoreMutation to
return false id one of he sibblings has that flag set to true?
I believe it needs to use VClock of deleted sibbling as well?
Thanks
Daniel
The .withoutFetch() method isn't available when using the DomanBucket.
