massive loading problems

[TheFausap]

Hello,

I'm running redis under Mac OS X 10.11.4, but I have some problems with loading some data: Here is the output. It seems the data has been sent too fast to be handled properly with client.

Attached there's my source code.

`include

include

include <cpp_redis/cpp_redis>

cpp_redis::redis_client client;

int main(int argc, char* argv[]) {
client.connect();

std::string arg (" ");
int size = 100;

for(auto i=1;i<=size;i++) {
std::cout << "Deleting hash cta:"+std::to_string(i) << std::endl;
client.send({"HDEL ", "cta:"+std::to_string(i)});
std::cout << "DONE DEL" << std::endl;
}

std::cout << "creating values default" << std::endl;

for(auto i=1;i<=size;i++)
arg += " v" + std::to_string(i)+ " -1";
std::cout << "DONE DEL" << std::endl;
}

std::cout << "creating values default" << std::endl;

for(auto i=1;i<=size;i++)
arg += " v" + std::to_string(i)+ " -1";

std::cout << arg << std::endl;

for(auto i=1;i<=size;i++) {
std::cout << "Creating hash cta:"+std::to_string(i) << std::endl;
client.send({"HMSET", "cta:"+std::to_string(i), arg}, [](cpp_redis::reply& reply) {
std::cout << reply.as_string() << std::endl;
});

std::cout << "DONE CREATE" << std::endl;

}

client.disconnect();

return 0;
}`

Hi,

In fact, you are not passing the arguments as expected.
HMSET is expecting a list of "field value" arguments. To be properly formatted, each pair of "field value" has to be a different entry in the vector of arguments passed to redis_client::send.

The redis server expects a very strict format to treat each request.
cpp_redis formats the requests, but only by merging the different arguments specified in the vector of arguments. Each string entry within that vector is left unmodified.

  std::vector<std::string> arg;

  arg.push_back("HMSET");
  arg.push_back("cta:");

  for(auto i=1;i<=size;i++)
    arg.push_back("v" + std::to_string(i)+ " -1");

  for(auto i=1;i<=size;i++) {
    arg[1] = "cta:"+std::to_string(i);
    client.send(arg, [](cpp_redis::reply& reply){
      std::cout << reply.as_string() << std::endl;
    });
  }

This code works fine on my computer, could you confirm that it solved your issue?
