We have build another interesting proect pika. Pika is a nosql compatible with redis protocol with huge storage space. You can have a try.
QConf is a Distributed Configuration Management System! A better replacement of the traditional configuration file. As designed, configuration items which is constantly accessed and modified should be completely separated with application code, and QConf is where it should be.
- Changes to any configuration will be synchronised to all client machines in real-time.
- High query efficiency.
- Convenient deployment and simple interface.
- High robustness and fault-tolerance.
- support c/c++, shell, php, python, lua, java, go, node and etc.
The QConf is built using CMake (version 2.6 or newer).
On most systems you can build the library using the following commands:
mkdir build && cd build cmake .. make make install
Alternatively you can also point the CMake GUI tool to the CMakeLists.txt file.
To install the QConf you can specify the install prefix by setting:
cmake .. -DCMAKE_INSTALL_PREFIX=/install/prefix
Set up Zookeeper servers, create or modify znode with Zookeeper Client
More information about Zookeper: ZooKeeper Getting Started Guide
Register the Zookeeper server address with QConf
# all the zookeeper host configuration. #[zookeeper] zookeeper.test=127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183 #zookeeper of idc 'test'
- Assign local idc
echo test > QCONF_INSTALL_PREFIX/conf/localidc #assign local idc to 'test'
- Run QConf
cd QCONF_INSTALL_PREFIX/bin && sh agent-cmd.sh start

- running times : ten million times altogether
- data size : the size of value of each key is 1k
- test method : multi-processes are running at the same time, and get the elapsed time that ten million times are running
- machine : Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz, 24 cores; 64G memory
- language : c++
- the lantency is 16μs
- during multi-process, the QPS can reach one million
qconf get_conf /demo/node1 # get the value of '/demo/node1'
// Init the qconf env ret = qconf_init(); assert(QCONF_OK == ret); // Get Conf value char value[QCONF_CONF_BUF_MAX_LEN]; ret = qconf_get_conf("/demo/node1", value, sizeof(value), NULL); assert(QCONF_OK == ret); // Destroy qconf env qconf_destroy();
