To optimize a fast key-value store, select an appropriate hash table variant like Robin Hood hashing and tune the load factor to minimize lookup times and optimize access patterns.

Use probabilistic data structures like Bloom filters and HyperLogLog for memory optimization in performance-critical applications where approximate membership or cardinality estimates are acceptable.

Implementing a custom collection requires applying principles for custom implementations based on specific performance constraints, balancing memory optimization and access patterns to prevent over-engineering.

Optimize range query performance by selecting specialized data structures like segment trees or Fenwick trees, which efficiently handle range queries in performance-critical applications.

Balanced binary search trees and skip lists offer different performance characteristics for ordered data access, and choosing between them depends on specific access patterns and performance requirements.

Avoid using a hash table over a balanced tree when your application requires ordered traversal or range queries, as hash tables provide constant-time lookups without maintaining element order.
