Event Types

The type field in mutation items specifies the operation to perform:

Type	Description
INSERT	Create a new edge or update an existing edge with a new version
UPDATE	Update properties of an existing edge
DELETE	Delete an edge (marks it as deleted)

Lock Parameter

The lock parameter controls whether to acquire a lock during mutation:

• true (default): Acquires a lock to prevent concurrent modifications. Ensures data consistency but may have higher latency.
• false: Skips locking. Faster but may lead to race conditions if multiple mutations target the same edge simultaneously.

Note: It is recommended to use lock=true in production environments to ensure data consistency.
