I chose bug as issue type. Actually I never know and never make decision about this is a normal behavior or not.
I've gone through official documentations and searched jira platform about this issue but I could not any thing. Forgive me please if I had overlooked somethings.
When using bulk operation with option journaling false it doesn't return `code: 11000` duplicate key error.
When using following options, it *doesn't return* errors:
- `
{ j:false }
`
- `
{ w:0, j:false }
`
When using following options, it *returns* `duplicate key` errors:
- `
{ w:"majority", j:false }
`
- `
{ w:0, j:true }
`
- `
{ w:"majority", j:true }
`
Code for example:
var ObjectId = mongoose.Types.ObjectId,
User = require('./models/user')
let bulk = User.collection.initializeUnorderedBulkOp()
let doc1 = {
"branch" : "DUPLICATE",
"department" : ObjectId("582bf1d8322809041e667777"),
}
let doc2 = {
"branch" : "TEST_SUCCESS",
"department" : ObjectId("582bf1d8322809041e668888"),
}
let doc3 = {
"branch" : "DUPLICATE",
"department" : ObjectId("582bf1d8322809041e669999"),
}
bulk.insert(doc1)
bulk.insert(doc2)
bulk.insert(doc3)
let bulkOptions = {
w:0,
j:false // next run change argument j as true
}
bulk.execute(bulkOptions, (err, result) => {
let writeErrors = result.toJSON().writeErrors
for (let i = 0; i > writeErrors.length - 1; i++) {
let error = writeErrors[i]
debug(error.toString())
}
})
Additionally the schema of User model has an unique compound index as `userSchema.index(
{ branch:1, department:1 },
{ unique: true })`
