Redis 插入乱序，或排序奇怪? [英] Redis inserting out of order, or sorting oddly?

问题描述

我有一些这样写的代码:

I have some code written like this:

foreach ($models as $model) {
    Redis::hset('model_App\ServiceModel', $model[$primaryKey], json_encode($model->toArray()));
}

模型按名称字段的字母顺序排列在 foreach 之前(alpha、green、zed)

The models are ordered alphabetically by name field prior to the foreach (alpha, green, zed)

数据，一旦添加到redis，看起来像这样:

The data, once added to redis, looks something like this:

row  | key  | value
1     490   {"service_id":490, "name":"zed"}
2     489   {"service_id":489, "name":"alpha"}
3     491   {"service_id":491, "name": "green"}

有谁知道为什么我的订单被忽略/覆盖?我是否缺少有关 redis 工作原理的信息?'row' 是否像 MySQL 数据库中的自动递增 ID，如果是这样 - 它是如何在 'alpha' 之前变成 'zed' 的?

Does anyone know why my ordering is being ignored / overwritten? Am I missing something about how redis works? Is 'row' like an auto incrementing id in a MySQL DB, and if so - how is it getting 'zed' before 'alpha'?

这是我第一次认真"使用它，我很感激我能得到的所有建议.

This is the first time I am 'seriously' using it, and I appreciate all the advice I can get.

推荐答案

Redis 的哈希是无序的 - 这是预期的行为.如果需要排序，请考虑使用排序集，SORT 命令，或(最好)对客户端中的数据进行排序.

Redis' Hashes are unordered - that is the expected behavior. If sorting is needed, either look into using Sorted Sets, the SORT command, or (preferably) sorting the data in the client.
