- 文件名中包含哪些信息?
- 每个文件名都有一个数字字符串,例如:
dcm_account1234_impression_2016022601_20160225_234912_218211994.csv.gz
2016022601
采用 YYYYMMDDHH
格式。这是文件中事件的世界协调时间 (UTC)(小时为 0 到 23)。
20160225_234912
采用 YYYYMMDD_HHMMSS
格式。这是以当地帐号时间(DCM 和统一)或 EST(仅限 DBM)生成报告的时间。
218211994
是文件 ID。
- 如何知道所有文件何时递送?
- 每天都有:
- 24 个点击文件(小时 0-23)。
- 24 个展示文件(第 0-23 小时)。
- 1 个活动文件。
- 21 个匹配表。
采用自定义配置的客户端可能有不同的编号。
- 如果我遇到同一日期和时间的重复文件,该怎么办?
- 这些都可能会发生。如果多个文件的日期/小时时间戳相同,请根据文件名时间戳使用最近分钟 / 秒的文件。
- 我认为我的某些数据不正确,该怎么办?
- 请向您的支持代表说明此问题的相关信息。如果数据似乎缺失,请详细说明缺少哪些小时以及哪些文件未考虑在内。
- 如何找出 v2 中已弃用的内容,或为了匹配表而移动的内容?
- 如需了解从 v1 到 v2 的映射,请参阅迁移指南。

This is the UTC hour for events in that file (hours are numbered 0 to 23).\n - `20160225_234912` is in `YYYYMMDD_HHMMSS` format. This is the time the report was generated in local account time (DCM and unified) or EST (DBM only).\n - `218211994` is the file ID.\n\nHow do I know when all files are delivered?\n: For each day there are: \n\n - 24 click files (hours 0-23).\n - 24 impression files (hours 0-23).\n - 1 activity file.\n - 21 match tables.\n\n Clients with custom configurations may have different numbers.\n\nWhat if I encounter duplicate files for the same date and hour?\n: This can happen. When more than one file has the same date/hour stamp, use the one with the\n latest minutes / seconds, based on the filename timestamp.\n\nI think some of my data is incorrect, what can I do?\n: Contact your support representative with information about the problem. If data\n seems to be missing, provide details about which hours are missing, and files that aren't\n accounted for.\n\nHow do I find out what's been deprecated in v2, or moved to match tables?\n: See the [migration guide](../migrating) for information on mapping from v1 to v2."]]
