Bulk Rejections Test

This Rally track is used to test the relationship between bulk indexing rejections and the following parameters:

• Number of concurrent clients indexing into Elasticsearch
• Number of shards actively being indexed into
• Number of data nodes in the cluster
• Size of bulk requests

The track contains a number of challenges, each indexing into an index with a set number of shards using a increasing number of concurrent client connections and two different bulk sizes.

对于冲泡咖啡来说，最重要的两个原材料就是「好水」、「好咖啡」，当我们万事俱备的时候，就进入到萃取的步骤了。

所有不同的萃取方式的准备部分，大部分都是一致的——选择使用烘焙好的咖啡豆，研磨至合适的颗粒粗细，然后加水。在咖啡粉一旦加入水之后，萃取就开始了。

在经验缺乏的时候，我们可能无法在萃取的过程中，精确地分辨出咖啡是被完美萃取了还是被错误的萃取。但是我们可以通过品鉴分辨出咖啡萃取的对错。

水会萃取出咖啡中含有香气的物质：最首先的是油脂和酸酯，然后是糖份，最后是木质成分。从风味和醇厚度上面来说明一下，就是处于这样的状态：

酸酯/油脂 — 甜/糖浆感 — 苦/空洞感
