Extremely Fast Compression algorithm. Contribute to lz4/lz4 development by creating an account on GitHub.

- Embed small scalars directly in the hash slot, avoiding value allocations for tiny entries - Switch compression from FastLZ to LZ4 (better ratio and speed) - get() accepts an optional $default argument (returned on miss instead of NULL) - dump() gains an $offset parameter and reports hits, atime, embedded and c_len per entry - Per-entry hit counters and start_time exposed in info()/dump() - Multi-get omits missing keys (filled with $default when given) instead of false placeholders - Field-by-field slot commits and spinlock backoff (pause/yield) reduce contention overhead - Fixed a startup hang when values_memory_size is below the 4M segment minimum - Fixed Windows shared memory cleanup (view unmapped exactly once) - Fixed valgrind-reported leaks and uninitialized reads (MINFO output, compression error paths)
