Question

我想为集合添加索引（data_04），但是在mongo shell中执行它之后

mongos> db.data_04.createIndex({"column1":1, "column":1,cacheDataTime:1 })

但经过相当长的一段时间，它仍然没有完成。所以我想明确地杀死它并在后台创建它。但我首先应该知道它的opid，我尝试了以下方式所有没有输出

# The following example returns information on index creation operations:
mongos> db.currentOp(
...     {
...       $or: [
...         { op: "query", "query.createIndexes": { $exists: true } },
...         { op: "insert", ns: /\.system\.indexes\b/ }
...       ]
...     }
... )

"inprog" : [ ],
"ok" : 1

mongos> db.currentOp(
...    {
...      "active" : true,
...      "ns" : /data_04/
...    }
... )

"inprog" : [ ],
"ok" : 1

那么错误以及如何找到索引创建操作的opid？

Answer 1

就我而言，它应该是

db.currentOp(
    {
      $or: [
        { op: "command", "query.createIndexes": { $exists: true } },
        { op: "insert", ns: /\.system\.indexes\b/ }
      ]
    }
)

                    "column1" : 1,
                    "column" : 1,
                    "cacheDataTime" : 1
                },
                "name" : "column1_1_column_1_cacheDataTime_1",
                "background" : true
