Concurrent Set

Definitions

1. A set data structure designed to support safe inserts, removals, and membership checks from multiple concurrent contexts. Concurrent sets are useful for tracking active IDs, deduplicating work, and maintaining shared membership state without serializing every operation through one thread.

   In plain English: A set data structure that can be safely used concurrently.

   Example: "The crawler used a concurrent set of visited URLs so workers could deduplicate tasks without racing each other."
