-- **Note:** Analyzer only compute stats of Filter ops. So extra Mapper or Deduplicator ops will be ignored in the analysis process.
+- **Note:** Analyzer only compute stats for Filters that produce stats or other OPs that produce tags/categories in meta. So other OPs will be ignored in the analysis process. We use the following registries to decorate OPs:
+  - `NON_STATS_FILTERS`: decorate Filters that **DO NOT** produce any stats.
+  - `TAGGING_OPS`: decorate OPs that **DO** produce tags/categories in meta field.

-* **注意**：Analyzer 只计算 Filter 算子的状态，其他的算子（例如 Mapper 和 Deduplicator）会在分析过程中被忽略。
+* **注意**：Analyzer 只用于能在 stats 字段里产出统计信息的 Filter 算子和能在 meta 字段里产出 tags 或类别标签的其他算子。除此之外的其他的算子会在分析过程中被忽略。我们使用以下两种注册器来装饰相关的算子：
+  * `NON_STATS_FILTERS`：装饰那些**不能**产出任何统计信息的 Filter 算子。
+  * `TAGGING_OPS`：装饰那些能在 meta 字段中产出 tags 或类别标签的算子。
