Concurrent Map
Noun · Development
Definitions
A map or dictionary implementation designed for safe access and updates by multiple threads or tasks at the same time. Concurrent maps typically use locks, segmentation, or lock-free techniques so reads and writes can proceed without corrupting shared state.
In plain English: A map data structure that can be safely used by multiple concurrent operations.
Example: "The metrics registry used a concurrent map so counters could be created lazily during request handling without global locking around every read."
