the fastest in-memory index in the East(maybe the fastest on this planet)

A library that provides various concurrent algorithms for in-memory index, aims to achieve extremely FAST speed, but just for EXPERIMENT and FUN.

Algorithms

  • Palm Tree (palm/)
  • Blink Tree (blink/)
  • Mass Tree (mass/)
  • Adaptive Radix Tree (art/)
  • Height Optimized Trie (hot/) (developing)

Have a Try

#              thread_num  thread_key_number
./run.sh  palm   4           100   # test palm tree

./run.sh  blink  4           100   # test blink tree

./run.sh  mass   4           100   # test mass tree

./run.sh  art    4           100   # test art tree

Benchmark

Benchmark Multi ART

Multi ART is capable of reaching 100 million insert per second on a 96-core machine using 64 threads.
