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.
> Minimize network calls required when completing direct upload
> -------------------------------------------------------------

> Key: OAK-8574
> URL: https://issues.apache.org/jira/browse/OAK-8574
> Project: Jackrabbit Oak
> Issue Type: Technical task
> Components: blob-cloud, blob-cloud-azure
> Affects Versions: 1.16.0, 1.10.4
> Reporter: Matt Ryan
> Assignee: Matt Ryan
> Priority: Major
>
> 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.
