[英]MongoDB TTL index does not remove an expired record
I created a TTL index on my collection's created_at
field to autoremove document after 30s but after sometime passed (5min later) the document didn't get removed.我在我的集合的
created_at
字段上创建了一个 TTL 索引,以便在 30 秒后自动删除文档,但经过一段时间后(5 分钟后),文档没有被删除。 I read some related questions and I'm sure there was no typo in my collection.我阅读了一些相关问题,我确信我的收藏中没有错字。 Here is the JSON after running
db[collectionName].getIndexes()
这是运行
db[collectionName].getIndexes()
后的 JSON
[
{
"v" : 2,
"key" : {
"_id" : 1
},
"name" : "_id_",
"ns" : "record_db.collectionName"
},
{
"v" : 2,
"key" : {
"created_at" : 1.0
},
"name" : "created_at_1",
"ns" : "record_db.collectionName",
"expireAfterSeconds" : 30.0
}
] And here is an example document: ] 这是一个示例文档:
{
"_id" : ObjectId("5fc3823af29f9d9eb1518857"),
"record_path" : path/to/file,
"timestamp" : 1606648392,
"humantime" : "29/11/2020 18:12:58",
"created_at" : ISODate("2020-11-29T18:12:58.859Z")
}
ISODate("2020-11-29T18:12:58.859Z") not happened yet. ISODate("2020-11-29T18:12:58.859Z") 还没有发生。
const iso = "2020-11-29T18:12:58.859Z" const date = new Date(iso); console.log(date.toString());
