What is the Lock Striping Pattern?

A concurrency optimization pattern that reduces lock contention by dividing a single lock into an array of multiple locks.

If you have a highly concurrent Hash Map, locking the entire map for every write creates a massive bottleneck. Lock Striping partitions the data (e.g., by hash buckets) and assigns a different lock to each partition. Multiple threads can write concurrently as long as they hit different partitions.
