我们将使用 `url` 函数将数据流式传输到 ClickHouse。我们需要首先预处理一些传入的数据，其中包括：
- 将`postcode` 拆分为两个不同的列 - `postcode1` 和 `postcode2`，因为这更适合存储和查询
- 将`time` 字段转换为日期为它只包含 00:00 时间
- 将`time` 字段转换为日期因为它只包含 00:00 时间
- 忽略 [UUid](/docs/zh/sql-reference/data-types/uuid.md) 字段，因为我们不需要它进行分析
- 使用 [transform](/docs/zh/sql-reference/functions/other-functions.md#transform) 函数将 `Enum` 字段 `type` 和 `duration` 转换为更易读的 `Enum` 字段
- 将 `is_new` 字段从单字符串（` Y`/`N`) 到 [UInt8](/docs/zh/sql-reference/data-types/int-uint.md#uint8-uint16-uint32-uint64-uint256-int8-int16-int32-int64 -int128-int256) 字段为 0 或 1
