------------------------------
Summary: 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: Improvement
Components: blob-cloud, blob-cloud-azure
Affects Versions: 1.10.4, 1.16.0
Reporter: Matt Ryan
Assignee: Matt Ryan
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.
