性能

要对RedisJSON的功能有一个初步的了解，可以使用它进行测试redis-benchmark就像任何其他Redis命令。然而，为了更好地控制测试，我们将使用一个用Go编写的工具ReJSONBenchmark我们希望在不久的将来发布。

以下数据来自AWS EC2 c4.8xlarge实例，该实例同时运行Redis服务器和基准测试工具。到服务器的连接是通过网络堆栈进行的。所有测试都是非流水线的。

注意:下面的结果是使用RedisJSON的预览版本测量的，它仍然是非常未优化的。

RedisJSON基线

一个小对象

我们测试一个有趣的JSON值，尽管它是纯合成的。测试对象是/测试/文件/通过- 100. - json，重380个字节，并且是嵌套的。我们首先测试设置它，然后使用几个不同的路径获取它:

ReJSONBenchmark传递- 100. - json

ReJSONBenchmark传递- 100. - jsonpercentiles

一个更大的数组

转到更大的值，我们使用1.4 kB数组/ /文件/通过测试- jsonsl 1. - json：

ReJSONBenchmark传递- jsonsl - 1. - json

ReJSONBenchmark传递- jsonsl - 1. - jsonpercentiles

一个稍大的对象

总结一下，现在我们将采用一个不少于3.5 kB的庞然大物/ /文件/通过测试- json解析器- 0000. - json：

ReJSONBenchmark传递- json解析器- 0000. - json

ReJSONBenchmark传递- json解析器- 0000. - jsonpercentiles

操作数

最后但同样重要的是，一些加法和乘法:

ReJSONBenchmark操作数

ReJSONBenchmark数字操作百分比

基线

为了建立基线，我们将使用Redis平命令。首先，让我们看看是什么redis-benchmark报告:

~$ redis/src/redis-benchmark -n 1000000 ping ====== ping ====== 1000000 requests completed in 7.11 seconds 50 parallel clients 3 bytes payload keep alive: 1 99.99% <= 1毫秒100.00% <= 1毫秒140587.66 requests per second

ReJSONBenchmark的并发性是可配置的，因此我们将测试几个设置以找到一个好的设置。以下是结果，表明16个工人产生的最佳吞吐量:

ReJSONBenchmark平

ReJSONBenchmark萍百分位数

请注意，我们的基准测试工具在ping方面的表现略差——仅产生116K的ops，与之相比redis-cli140 k。

空字符串

另一个RedisJSON基准是设置和获取一个空字符串-一个只有两个字节长的值(即。＂＂)．当然，这不是很有用，但它教会了我们一些关于模块的基本性能:

ReJSONBenchmark空字符串

ReJSONBenchmark空字符串百分比

比较服务器端Lua脚本

我们比较了RedisJSON与Redis的嵌入式Lua引擎的性能。为此目的，我们使用Lua脚本/标准/ lua．这些脚本为以JSON或MessagePack格式存储的值提供了RedisJSON的GET和SET功能。每个不同的操作(设置根、获取根、设置路径和获取路径)都是通过每个“引擎”在大小不同的对象上执行的。

设置和获取根结点

在这个测试中，存储原始JSON的性能最好，但这并不奇怪，因为它所做的只是提供未处理的字符串。虽然你可以并且应该使用Redis缓存不透明的数据，JSON“blobs”只是一个例子，这不允许任何更新，除了这些整个值。

因此，更有意义的比较是在RedisJSON和MessagePack变体之间，因为两者都在实际存储传入的JSON值之前处理它。虽然这两种方法的速率和延迟表现非常相似，但绝对测量结果表明RedisJSON的性能可能会进一步提高。

设置和获取对象的部分

这个测试显示了RedisJSON存在的原因。它不仅优于Lua变体，而且不管对象的总体大小，它都能保持恒定的速率和延迟。这里没有什么神奇之处——RedisJSON保持了值的反序列化，因此访问它的部分是一个相对便宜的操作。与之形成鲜明对比的是原始JSON和MessagePack，它们需要在对整个对象进行任何操作之前解码整个对象(对象越大，这个过程的开销就越大)。
