simple_flow一个简单的流式计算框架

simple_flow

simple realtime flow computation

简介

simple_flow 是一个简单的实时流计算框架,由两部分组成,一个是agent,一个是flow_server, agent负责将数据实时传输给flow_server,flow_server负责对实时流的处理

特点

• linux only
• 继承simple系列的传统,简洁实用
• 安全,可靠 -- 采用拉模式,对数据源系统依赖,影响小

依赖

• simple_log 日志组件

构建 && 测试

  make && make test # 此步骤会生成一个agent和一个测试用的flow_server
  ./bin/flow_server_test # start flow_server to receive flow
  ./bin/fileagent localhost 3491 /tmp/test.log # usage: ./bin/fileagent flow_server_ip flow_server_port file_path

代码示例

#include <fstream>
#include "simple_log.h"
#include "flow_handler.h"
#include "flow_server.h"

class LogFlowHandler : public FlowHandler {

public:
    int do_handle(char *flow_bytes, int size) {
        std::string receive_flow = std::string(flow_bytes, size);
        LOG_DEBUG("start handle the size:%d, flows %s", size, receive_flow.c_str());
        return 0;
    }
};

int main() {
    FlowServer flow_server;
    flow_server.start(3491, new LogFlowHandler());
    return 1;
}
