Tokyo Cabinet is a library of routines for managing a database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value. There is neither concept of data tables nor data types. Records are organized in hash table, B+ tree, or fixed-length array.

User Defined Functions (UDF's) via Lua

As of mid '08, Hirabayashi-san embedded Lua into Tokyo Cabinet's runtime to allow for easy extensibility of the database. There is a common set of Lua API's built in, which allow you to interact with the underlying data, execute your extensions remotely, or even on a timer. This allows us to build additional functionality on top of the Tokyo Cabinet database with Lua!

A few examples you will find in this repository:

  • Simple echo application

  • Implemention of sets operations (like Redis) on top of TC

  • Example of executing Map-Reduce jobs on data within TC

  • TTL / Expire functionality (like memcached)

  • and many others…

Please do fork the repo and add your recipes to the list!
