从Redis取回多个钥匙时死锁

Question

我试图并行地将此查询的结果发送到redis (使用stackexchange C#客户端)，但不知何故我在死锁中运行，并且不确定在哪里

检索数据的方法：

public LiveData Get(string sessionId)
{
    return GetAsync(sessionId).Result;
}

private async Task<LiveData> GetAsync(string sessionId)
{
    var basketTask = GetBasketAsync(sessionId);
    var historyTask = GetHistoryAsync(sessionId);
    var capturedDataTask = GetCapturedDataAsync(sessionId);

    var basket = await basketTask;
    var history = await historyTask;
    var capturedData = await capturedDataTask;

    return new LiveData
    {
        Basket = basket.IsNullOrEmpty
            ? new List<Product>()
            : JsonConvert.DeserializeObject<List<Product>>(basket),
        History = history.Select(cachedProduct
            => JsonConvert.DeserializeObject<Product>(cachedProduct.Value.ToString())).ToList(),
        CapturedData = capturedData.ToDictionary<HashEntry, string, object>(
            hash => hash.Name, hash => JsonConvert.DeserializeObject(hash.Value))
    };
}

从redis中获取缓存数据的方法如下：

private async Task<RedisValue> GetBasketAsync(string key)
{
    key = $"{key}{BasketSuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.StringGetAsync(key);
}

private async Task<HashEntry[]> GetHistoryAsync(string key)
{
    key = $"{key}{HistorySuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.HashGetAllAsync(key);
}

private async Task<HashEntry[]> GetCapturedDataAsync(string key)
{
    key = $"{key}{CapturedDataSuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.HashGetAllAsync(key);
}

我认为这样调用KeyExpireAsync很好，只是因为可以触发和忘记，但不确定这是否可能相关(我甚至尝试删除它，但它仍然被阻止)
