How to use Redis within a C++ program?

c++ database redis

Solution 1

Using a C bindings library? There doesn't seem to be a C++ wrapper available anywhere.

Solution 2

I have forked the fictorial redis-cplusplus-client, made it compatible to redis-server v2.0, added missing api calls and implemented consistent hashing. There is also an early state of high level classes that will be useable like stl types in the near future (shared_string, shared_int, shared_set, ...). Nothing is production ready yet but the provided tests are succesfully running :-)

Official list of C++ clients

Explore a full list of Redis C++ clients on redis.io. You will find there different clients based on boost, Qt, etc. Note that at this time none of the C++ client implementations are marked as "Recommended." But there is a recommended C client, hiredis, which should work just fine in C++.

Solution 4

I wrote a C++ Redis client: redis-plus-plus. It's based on hiredis, and written in C++11. It supports the following features:

Most commands for Redis.
Connection pool.
Redis scripting.
Thread safe unless otherwise stated.
Redis publish/subscribe.
Redis pipeline.
Redis transaction.
Redis Cluster.
Redis Sentinel.
Redis Stream.
STL-like interface.
Generic command interface.

It's very fast, and easy to use. If you have any problem with this client, feel free to let me know. If you like it, also feel free to star it :)

#include <sw/redis++/redis++.h>
using namespace sw::redis;

try {
    Redis redis("tcp://127.0.0.1:6379");

    redis.set("key", "val");
    auto val = redis.get("key");
    if (val) {
        // dereference val to get the value of string type.
        std::cout << *val << std::endl;
    }   // else key doesn't exist.

    redis.rpush("list", {"a", "b", "c"});
    std::vector<std::string> list;
    redis.lrange("list", 0, -1, std::back_inserter(list));

    // put a vector<string> to Redis list.
    redis.rpush("another-list", list.begin(), list.end());

    auto tx = redis.transaction();

    auto tx_replies = tx.incr("num0")
                        .incr("num1")
                        .mget({"num0", "num1"})
                        .exec();

    auto redis_cluster = RedisCluster("tcp://127.0.0.1:7000");

    // RedisCluster has similar interface as Redis.
    redis_cluster.set("key", "value");
    val = redis_cluster.get("key");
} catch (const Error &err) {
    // error handling.
}

I've just released my c++ redis client on github. It's main feature right now is pipelining, I'll be adding more features soon, possibly sharding/consistent hashing next.
