versionNumber property
Represents the existing version (freshness) of the product, which can be used to preserve the right order when multiple updates are done at the same time.
If set, the insertion is prevented when version number is lower than the
current version number of the existing product. Re-insertion (for example,
product refresh after 30 days) can be performed with the current
version_number. Only supported for insertions into primary data sources.
Do not set this field for updates. Do not set this field for insertions
into supplemental data sources. If the operation is prevented, the aborted
exception will be thrown.
Optional. Immutable.
