Why did you choose UUID for taskId instead of Long/BigInt?

UUID (Universally Unique Identifier) is chosen for taskId instead of Long/BigInt for several reasons:

• Global uniqueness: UUID guarantees uniqueness not only within a single database but also across different systems, which is important in distributed systems or integrations.
• No collisions when generated on different nodes: UUIDs can be generated locally without the need for a centralized server to issue unique numbers.
• Security and predictability: Unlike sequential numbers, UUIDs are harder to predict, which can be an advantage in some scenarios.

Example of generating a UUID in Java:

import java.util.UUID;

UUID taskId = UUID.randomUUID();
System.out.println(taskId.toString());

However, it is worth noting that UUIDs take up more space and may be less efficient for indexing compared to Long/BigInt.
