Description
Hello,
I was playing with transactions provided by couchbase and spring data following the documentation from here
I noticed that there's a difference if I persist a document with a repository or with a transaction.
Here are details :
spring-boot 2.7.2
couchbase-transactions 1.2.4
Simple entity
@Document
@Scope("dev")
@Collection("schedule")
data class Schedule(
@field:Id
val id: String,
val nested: Nested,
@field:Field
val list: List<String>
)
data class Nested(
@field:Field("isFree")
val free: Boolean
)
Repository
interface ScheduleRepository : ReactiveCouchbaseRepository<Schedule, String>Service
private val collection = clientFactory.withScope("dev").getCollection("schedule").reactive()
fun saveScheduleWithRepo(schedule: Schedule) = repository.save(schedule)
fun saveScheduleAsDocWithTransaction(schedule: Schedule): Mono<TransactionResult> {
val target = CouchbaseDocument()
converter.write(schedule, target)
return transactions.reactive().run {
it.insert(collection, target.id, target.content)
.then()
}
}val schedule = Schedule("1", Nested(true), listOf("TEST"))
return service.saveScheduleWithRepo(schedule)
.flatMap {
service.saveScheduleAsDocWithTransaction(schedule.copy(id = "2"))
}Here are differences :
| with repository | as doc with transaction |
{
"_class": "com.rbleuse.spring.reactive.couchbase.model.Schedule",
"list": [
"TEST"
],
"nested": {
"isFree": true
}
} |
{
"_class": "com.rbleuse.spring.reactive.couchbase.model.Schedule",
"list": {
"empty": false
},
"nested": {
"content": {
"isFree": true
},
"id": null,
"expiration": 0
}
} |
As you can see, inserting the document with a transaction adds extra fields to the document : content, id and expiration (all in nested). Shouldn't it be in root object instead ?
Furthermore, my simple list of string is not converted into an array with the actual String value.
If I convert my List into an Array in my data class, result is same when using a transaction.
Did I miss something ?
