 - Resource attributes and span attributes are automatically flattened into separate columns, with column names being their JSON keys (using `.` to connect multiple levels of nesting)
 - `span_events` and `span_links` are stored as JSON data types by default
 
-By default, the table is partitioned into 16 uniform regions based on the `trace_id` to efficiently store and query all trace data.
+Note: 
+1. The `greptime_trace_v1` process uses the `trace_id` field to divide data into partitions for better performance. **Please make sure the first letter of the `trace_id` is evenly distributed**.
+2. For non-test scenarios, you might want to set a `ttl` to the trace table to avoid data overload. Set the HTTP header `x-greptime-hints: ttl=7d` would set a `ttl` of 7 days during the table creation, see [here](/reference/sql/create.md#table-options) for more details about `ttl` in table option.

-### Add Time Range for Getting Operations Endpoints
-
-By default, we don't add time range parameters for the `GET /api/operations` and `GET /api/services/{service}/operations` endpoints. When the volume of traces data is large, this may lead to long query times. You can add a time range parameter by setting the HTTP Header based on your specific scenario, for example:
-
-```
-x-greptime-jaeger-time-range-for-operations: 3 days
-```
-
-This indicates that only the Operations data from the past 3 days will be returned.
-
-This header can be set in the **HTTP Headers** of the Jaeger Data Source, for example:

-默认地，表会根据 `trace_id` 均匀划分为 16 个 Region 以高效地存储和查询所有的 traces 数据。
+注意: 
+1. `greptime_trace_v1` 处理方式默认通过 `trace_id` 字段将数据切分成不同的分区以提升性能。**请确保 `trace_id` 的第一个字符是分布均匀的**。
+2. 在非测试的场合下，可以通过设置 `ttl` 以避免持久化数据量过大。通过设置 `x-greptime-hints: ttl=7d` HTTP 请求头，在创建 trace 表时会添加一个 7 天的 `ttl` 表选项。见[此文档](/reference/sql/create.md#表选项)了解更多关于表选项 `ttl` 的信息。

-### 为获取 Operations 接口添加时间范围
-
-默认地，我们没有为 `GET /api/operations` 和 `GET /api/services/{service}/operations` 添加时间范围参数，当 traces 数据量较大时，这可能会导致查询时间过长。此时你可以基于自己的场景以 HTTP Header 的形式添加时间范围参数，比如：
-
-```

-这表示只返回最近 3 天的 Operations 数据。
