A memory-efficient hash_map tool that comes with just 2 bits of entry overhead.
This free and open source project is a template library that does not require installation of binary files. The hash-table implementations provided by Google SparseHash have similar API to SGI's hash_map class and the tr1 unordered_map class, but provide a different set of performance characteristics.
With the easy-to-use replace feature, replacing hash_map or unordered_map with sparse_hash_map or dense_hash_map in C++ code is a simple process. This feature helps developers to take advantage of the performance optimization provided by Google SparseHash seamlessly.
