Auto Increment IDs vs Custom Hash IDs

Developers should use Auto Increment IDs when they need a simple, reliable way to create unique identifiers for database records, especially in scenarios like user accounts, product catalogs, or transaction logs where manual ID assignment is error-prone meets developers should use custom hash ids when they need to generate public-facing identifiers that are secure, non-predictable, and do not reveal sensitive information like database row counts or sequential patterns, such as in restful apis, url shorteners, or e-commerce systems. Here's our take.

Auto Increment IDs

Nice Pick

Developers should use Auto Increment IDs when they need a simple, reliable way to create unique identifiers for database records, especially in scenarios like user accounts, product catalogs, or transaction logs where manual ID assignment is error-prone

Pros

  • +It is ideal for applications requiring fast inserts and sequential ordering, but alternatives like UUIDs should be considered for distributed systems or when IDs must be globally unique across databases
  • +Related to: database-design, sql

Cons

  • -Specific tradeoffs depend on your use case

Custom Hash IDs

Developers should use Custom Hash IDs when they need to generate public-facing identifiers that are secure, non-predictable, and do not reveal sensitive information like database row counts or sequential patterns, such as in RESTful APIs, URL shorteners, or e-commerce systems

Pros

  • +They are particularly useful for preventing enumeration attacks, improving user experience with readable IDs, and enabling features like referral codes or tracking tokens without relying on database primary keys
  • +Related to: hash-functions, cryptography

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Auto Increment IDs if: You want it is ideal for applications requiring fast inserts and sequential ordering, but alternatives like uuids should be considered for distributed systems or when ids must be globally unique across databases and can live with specific tradeoffs depend on your use case.

Use Custom Hash IDs if: You prioritize they are particularly useful for preventing enumeration attacks, improving user experience with readable ids, and enabling features like referral codes or tracking tokens without relying on database primary keys over what Auto Increment IDs offers.

The Bottom Line
Auto Increment IDs wins

Developers should use Auto Increment IDs when they need a simple, reliable way to create unique identifiers for database records, especially in scenarios like user accounts, product catalogs, or transaction logs where manual ID assignment is error-prone
