keyper

keyper is a simple key-value store, result of my NIH syndrome.

Warning

While this warning is here beware of very alpha piece of software.

Building and Installing

First you must install the following dependencies:

• [Kyoto Cabinet] 1
• [Apache Thrift] 2
• [Xapian Search Engine Library] 3
• [CMake cross-platform build system] 4

After that, to build the single server (keypers):

    make

Or these steps:

• generate C++ code from thrift IDL (on thrift directory): thrift -r --gen cpp keyper.thrift
• build keypers ("s" stands for single/server, distributed version to come), on server directory: cmake . make
• build clients stubs, thrift directory: thrift -r --gen py keyper.thrift # python thrift -r --gen rb keyper.thrift # ruby

Small python example (client directory): [cly.py] 5

Features

Supported types:

• key-value (with indexing)
• counters
• queues

Future

Support for:

• Security: Auth, cryptography
• Key expiration (LRU, etc)

Implement as a distributed system with the following features:

• No single point of failure
• Data distribution (sharding)
• Data replication (copies)
• No need to ever stop the system
• No limits (virtually)
• Advanced system control and monitoring
• Map-reduce tasks

I don't like licenses, because I don't like having to worry about all this
legal stuff just for a simple piece of software I don't really mind anyone
using. But I also believe that it's important that people share and give back;
so I'm placing this work under the following license.
