Develop C++ Apps

• YEDIS

• installed YugabyteDB, created a universe and are able to interact with it using the Redis shell. Ifnot please follow these steps in the .
• have C++11.

We use the driver. To install the library do the following:

• Clone the cpp_redis repository

• Get the networking module ()

$ cd cpp_redis
$ git submodule init && git submodule update

• Create a build directory and move into it

$ mkdir build && cd build

• Generate the Makefile using CMake

• Build and install the library

$ make
$ make install

#include <cpp_redis/cpp_redis>
#include<iostream>
#include<vector>
#include<string>
using namespace std;
int main() {
  cpp_redis::client client;
    if (status == cpp_redis::client::connect_state::dropped) {
      std::cout << "client disconnected from " << host << ":" << port << std::endl;
    }
  });
  string userid = "1";
  vector<pair<string, string>> userProfile;
  userProfile.push_back(make_pair("name", "John"));
  userProfile.push_back(make_pair("age", "35"));
  userProfile.push_back(make_pair("language", "Redis"));
  // Insert the data
  client.hmset(userid, userProfile, [](cpp_redis::reply& reply) {
      cout<< "HMSET returned " << reply << ": id=1, name=John, age=35, language=Redis" << endl;
  });
  client.hgetall(userid, [](cpp_redis::reply& reply) {
    if (reply.is_array()) {
      retVal = reply.as_array();
    }
    cout << "Query result:" <<endl;
    for (int i = 0; i < retVal.size(); i=i+2) {
      cout << retVal[i] << "=" <<retVal[i+1] << endl;
    }
  });
  // synchronous commit, no timeout
  client.sync_commit();
  return 0;
}

To compile the file, run the following command.

$ ./ybredis_hello_world

You should see the following output.

HMSET returned OK: id=1, name=John, age=35, language=Redis
Query result:
age=35
name=John
