压测方法

每 4 个 loadgen 使用批量写入接口 bulk 轮询压测同一集群的 7 个节点，每个请求写入 10000 个文档。

具体请求如下：

requests:
  - request: #prepare some docs
      method: POST
      runtime_variables:
#        batch_no: uuid
      runtime_body_line_variables:
#        routing_no: uuid
#      url: $[[env.ES_ENDPOINT]]/_bulk
      url: $[[ip]]/_bulk
      body_repeat_times: 10000
      basic_auth:
       username: "$[[env.ES_USERNAME]]"
       password: "$[[env.ES_PASSWORD]]"
      body: |
        {"index": {"_index": "nginx", "_type": "_doc", "_id": "$[[uuid]]"}}
        $[[message]]

总结

通过对不同场景的压测结果进行对比分析，得出以下结论：

• Easysearch 相比 Elasticsearch 的索引性能显著提升
  Easysearch 集群的吞吐性能提升了 40% - 70%，且随着分片数量的增加，性能提升效果更为显著。
• Easysearch 相比 Elasticsearch 的磁盘压缩效率大幅提高
  Easysearch 集群的磁盘压缩效率提升了 2.5 - 3 倍，并且随着数据量的增加，压缩效果愈发明显。

此测试结果表明，Easysearch 在日志处理场景中具有更高的性能与存储效率优势，尤其适用于大规模分片与海量数据的使用场景。
