我正在使用 Rally Lookback API 运行一些查询，似乎没有检索到超过 1 周的修订：

使用下面的查询：

{
    "ObjectID": 251038028040,
    "__At": "current"
}

结果：

{
    "_rallyAPIMajor": "2",
    "_rallyAPIMinor": "0",
    "Errors": [],
    "Warnings": [
        "Max page size limited to 100 when fields=true"

请记住，截至目前，该工件有 79 个修订版，最新修订版指向 2018 年 11 月 21 日下午 2:41 CST，根据 Rally Central 的修订标签。另一件事是，如果我在几分钟后运行查询，ETL 日期似乎正在更新，因为某种索引正在运行：

{
    "_rallyAPIMajor": "2",
    "_rallyAPIMinor": "0",
    "Errors": [],
    "Warnings": [
        "Max page size limited to 100 when fields=true"
    ],
    "GeneratedQuery": {
        "find": {
            "ObjectID": 251038028040,
            "$and": [
                {
                    "_ValidFrom": {
                        "$lte": "2018-11-21T14:45:50.565Z"
                    },
                    "_ValidTo": {
                        "$gt": "2018-11-21T14:45:50.565Z"
                    }
                }
            ],
            "_ValidFrom": {
                "$lte": "2018-11-21T14:45:50.565Z"
            }
        },
        "limit": 10,
....... rest of the code ommited.

Lookback API 有什么理由不应该处理当前数据而不是记录之间的一周差异？

【解决方案1】：

您的工作区数据目前似乎正在“重建”。 _ETLDate 是 LBAPI 数据库中最新修订的日期，最终应该会赶上当前修订的日期。
