why receive this error?

I write only this code.
Transactions transactions = Transactions.create(cluster);

setting

couchbase 7.0 beta ,
java sdk 3.0.10
spring boot 2.4
couchbase-transactions 1.1.3

Hi @leech
NoSuchMethodError almost always indicates a binary incompatibility between jars. Here I would guess that you’re using a later version of the Reactive library than the transactions library was built and tested with. I recommend including the transactions library in your Maven/gradle/SBT project and allowing the dependency manager to follow the transitive dependencies to pull in the correct version of the underlying Couchbase Java SDK and Reactive library, rather than explicitly specifying those.

hi graham. thank you for your answer.
It’s because couchbase 7.0 does not match Java SDK 3.0.10 . right?

i will have to wait for the new SDK version…? OKOK thank you graham!

graham.pople · November 30, 2020, 10:45am

Hi @leech
No the Couchbase Server version isn’t relevant here. The problem is that the transactions library is compiled against a particular version of a Reactive library, which includes this Flux.retryWhen method. But your project appears to be pulling in a different, incompatible, version of the Reactive library, that does not include that method.

The transactions library uses version 3.3.9 of the Reactive library. You can use your project management tool to get the transitive dependencies and see which project is pulling in a different, incompatible Reactive library.

I will also file a ticket to remove the transactions library dependency on this Flux.retryWhen method, since it appears to have been removed.

Thank you. @graham.pople
It’s My mistake… Sorry

reactor-core was using version 3.4.0. Is this the problem!!! Thank you
The problem have worked out. Thank you graham.

In additional, Can i use MutateIn method in transaction?
I want to access sub-document with transaction.

//  loop an error above

my action about this error

Change durability this bucket to majority and persistTomajority. but this is not solution.

I think this error key point is" With the current cluster configuration, the requested durability guarantees are impossible".

i was using one node,and my Bucket replica is 2.
What should I change?

I finded reason of this error here.

/**

reason is

" The given durability requirements are currently impossible to achieve, as not enough configured replicas are currently available."

Here’s my question:
A cluster of one node is not available JAVA SDK transaction?? I’m so sad.

Hi @leech

The Couchbase JAVA transaction SDK does support one node cluster.

The issue you are facing is due to the durability setting.By default, transaction uses durability as Majority. To achieve this, you need the cluster config mentioned in the below documentation

So for you config of 1 node and 2 replica’s, please change the replica to “Zero”

oh, My problem has been solved. thank you @praneeth.bokka !!!

In additional, Can i use MutateIn method with in transaction?
I want to access sub-document.

ingenthr · December 3, 2020, 6:23am

Not yet. This is something we’d like to do in the future, but it is full document only at the moment. Unless your documents are quite large, the difference in network usage shouldn’t be that much between Sub-Document and full document.

Hi @ingenthr Thank you for your answer.

also Thank you for your kind graham.pople , praneeth.bokka.
