Matt Ryan commented on OAK-8574:
--------------------------------

Note:  A fix for OAK-8575 would further reduce the number of API calls by one for both cases.

> The {{completeHttpUpload()}} in the cloud data store backends can be improved in terms of quantity of cloud storage service API calls.
> Suggestions include:
>  * Try a single {{getRecord()}} call at the beginning instead of calling {{exists()}}.  If an exception is thrown, catch it - this means the record doesn't exist and can be written.  If a record is returned, we don't write - and instead return this record.
>  * Don't check for existence after writing the record; instead assume that the record is written correctly if no error or exception from SDK.  Verify this behavior in unit tests.
>  * After writing the record, construct the record directly instead of calling {{getRecord()}} to do it.
> This removes two network API calls if the record is written and one if the record already exists.
