Create a timeseries collection:
> db.runCommand({create: "myts", timeseries: {timeField: "t", metaField: "sensor"}})
|
{
|
"ok" : 1,
|
...
|
}
|
Try to insert an invalid doc to it. Notice that {"n" : 1}, though nothing was inserted.
> db.runCommand({insert: "myts", documents: [{"metadata": { "sensor": 2}, "u": ISODate("2021-05-18T00:00:00.000Z"), "temp": 12}]})
|
{
|
"n" : 1,
|
"writeErrors" : [
|
{
|
"index" : 0,
|
"code" : 2,
|
"errmsg" : "'t' must be present and contain a valid BSON UTC datetime value"
|
}
|
],
|
"ok" : 1,
|
...
|
}
|
|
> db.myts.find().itcount()
|
0
|
For a non-timeseries collection, on a write error (say DuplicateKeyError) the correct n is returned:
> db.runCommand({insert: "basic4", documents: [{_id: 1}]})
|
{
|
"n" : 0,
|
...
|
"writeErrors" : [
|
{
|
"index" : 0,
|
"code" : 11000,
|
"errmsg" : "E11000 duplicate key error collection: test.basic4 index: _id_ dup key: { _id: 1.0 } found value: RecordId(3)",
|
"keyPattern" : {
|
"_id" : 1
|
},
|
"keyValue" : {
|
"_id" : 1
|
},
|
"foundValue" : NumberLong(3),
|
"duplicateRid" : NumberLong(3)
|
}
|
],
|
"ok" : 1,
|
...
|
}
