# Distributed Data Structures

GridGain provides distributed implementations of common data structures, including atomic types, sequences, latches, locks, semaphores, queues, and sets.

GridGain provides distributed implementations of common data structures that work across all cluster nodes, including atomic types, a distributed ID generator, count-down latches, locks, semaphores, queues, and sets.
