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/
) - B<sup>link</sup> 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.
