Summary

In this chapter, we explored how GQL transactions ensure that all procedures are either completed successfully or fail without affecting the GQL catalog and graph data partially.

A transaction can be serializable, concurrent, single-node, distributed, or read/write. Adhering to ACID rules is essential.

Transactions can be initialized implicitly or explicitly, with modes such as READ ONLY or READ WRITE, along with vendor-specific modes.

Committing a transaction applies all changes, and rolling back reverts them, maintaining data integrity and consistency across the system.

Transactions in GQL are a powerful tool for making operations clear and resettable. However, it’s important to assess whether ACID compliance is necessary for your scenarios. In many graph computing situations, ACID is not essential, and users often forgo it to enhance performance and save time.
