The latest server release has changed what output is generated in createIndexes command:
In previous releases (for example in 5.0.2) fields in output used a format with "boolean flag" like: `"_id" : true`. See wildcardProjection node:
MongoDB Enterprise replset:PRIMARY> db.runCommand({ "createIndexes" : "test_wildcard_index", "indexes" : [{ "key" : { "$**" : 1 }, "name" : "custom", "wildcardProjection" : { "b" : 1, "_id" : 0 } }] })
{
"numIndexesBefore" : 1,
"numIndexesAfter" : 2,
"createdCollectionAutomatically" : true,
"commitQuorum" : "votingMembers",
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1674661581, 2),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1674661581, 2)
}
MongoDB Enterprise replset:PRIMARY> db.test_wildcard_index.getIndexes()
[
{
"v" : 2,
"key" : {
"_id" : 1
},
"name" : "_id_"
},
{
"v" : 2,
"key" : {
"$**" : 1
},
"name" : "custom",
"wildcardProjection" : {
"b" : true,
"_id" : false
}
}
]
but in the recently released version the output uses a format with "a number flag" like `"_id" : 0`. See wildcardProjection node in output for 6.3.0-alpha-1336-gd798eac server:
MongoDB Enterprise replset:PRIMARY> db.runCommand({ "createIndexes" : "test_wildcard_index", "indexes" : [{ "key" : { "$**" : 1 }, "name" : "custom", "wildcardProjection" : { "b" : 1, "_id" : 0 } }] })
{
"numIndexesBefore" : 1,
"numIndexesAfter" : 2,
"createdCollectionAutomatically" : true,
"commitQuorum" : "votingMembers",
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1674660265, 2),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1674660265, 2)
}
MongoDB Enterprise replset:PRIMARY> db.test_wildcard_index.getIndexes()
[
{
"v" : 2,
"key" : {
"_id" : 1
},
"name" : "_id_"
},
{
"v" : 2,
"key" : {
"$**" : 1
},
"name" : "custom",
"wildcardProjection" : {
"b" : 1,
"_id" : 0
}
}
]
As I recall, the newly added format (with a number flag) was used in servers before 4.5 and then was replaced on a format with boolean flag. So now the previous format got back? Can someone clarify it?
