POST /cloud/v2/universes/{universe_id}/data-stores/{data_store_id}/entries/{entry_id}:increment — openapi

Increment Data Store Entry

Increments the value of the specified entry. Both the existing value and the increment amount must be integers.

If the entry doesn't exist, creates an entry with the specified value.

Incrementing specific revisions of the entry is unsupported. If you specify a revision ID in the path, the increment request will create a new entry with the @<revisionId> suffix as part of the key.

Known issue: the value may be incremented past the valid range of values. When this happens, the returned value will be clamped to the valid range, but the backend may persist the original value. This behavior is maintained for backwards compatibility reasons, but may change in a future version of this API.
