How do I choose a concurrency control algorithm?

What factors should I consider when choosing a concurrency control algorithm?

You should consider factors like the type of database, transaction volume, performance requirements, and consistency needs.

Can you explain the difference between optimistic and pessimistic concurrency control?

Sure! Optimistic concurrency control assumes conflicts are rare and checks for conflicts before committing, while pessimistic control locks resources to prevent conflicts.

Which algorithm is better for high transaction environments?

In high transaction environments, optimistic concurrency control is often preferred due to its lower locking overhead, but it depends on the specific use case.

Are there any trade-offs I should be aware of?

Yes, optimistic control can lead to higher abort rates under contention, while pessimistic control can cause delays due to locking.
