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：
λ date
Wed, Nov 28, 2018 2:26:45 PM
使用以下查询：
{
"ObjectID": 251038028040,
"__At": "current"
}
结果：
{
"_rallyAPIMajor": "2",
"_rallyAPIMinor": "0",
"Errors": [],
"Warnings": [
"Max page size limited to 100 when fields=true"
],
"GeneratedQuery": {

请记住，该工件目前有 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 的修订选项卡。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": [

},
"_ValidTo": {

}
}
],
"_ValidFrom": {
"$lte": "2018-11-21T14:45:50.565Z"
}
},
"limit": 10,
....... rest of the code ommited.
Lookback API 是否有任何理由不应该处理当前数据而不是记录之间的一周差异？
