Hi,
Using MongoDB version 3.6.7. Also tested on 4.0.2
Trying to create an index on two arrays using the shell:
db.test.createIndex({ "array1": 1, "array2": 1})
|
it fails with this error:
{
|
"operationTime" : Timestamp(1561615657, 1),
|
"ok" : 0,
|
"errmsg" : "cannot index parallel arrays [accountGrp] [links]",
|
"code" : 171,
|
"codeName" : "CannotIndexParallelArrays",
|
"$clusterTime" : {
|
"clusterTime" : Timestamp(1561615657, 1),
|
"signature" : {
|
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
|
"keyId" : NumberLong(0)
|
}
|
}
|
}
|
However, on the logs we only see:
2019-06-27T16:07:39.901+1000 I INDEX [conn18] build index on: test.test properties: { v: 2, key: {array1: 1.0, array2: 1.0 }, name: "index_arrays_name", ns: "test.test" }
|
2019-06-27T16:07:39.904+1000 I INDEX [conn18] building index using bulk method; build may temporarily use up to 500 megabytes of RAM
|
There's no failure recorded.
This limits out troubleshooting capabilities. We should logged some error on the server log.
