Microdict v0.1 is released : https://github.com/touqir14/Microdict What is Microdict? A high performance python hash table library that is generally faster and consumes significantly less memory than Python Dictionaries. Benchmarks show that it can be upto 7 times more memory efficient in comparison to Python Dictionaries. Microdict is a typed python dictionary that heavily relies on C extensions. Moreover, benchmarks show that its underlying C implementation can outperform both Google's Swiss Table and Facebook's F14 hash tables. Currently it supports the following 5 hash table types: "i32:i32" -> 32 bit signed keys and 32 bit signed values "i32:i64" -> 32 bit signed keys and 64 bit signed values "i64:i32" -> 64 bit signed keys and 32 bit signed values "i64:i64" -> 64 bit signed keys and 64 bit signed values "str:str" -> string keys and string values.
