    Hi! First question ever? Well, here I go. We have recently updated our mongodb version from 4.2 to 5, we're also updating dependencies and I'm trying to go from mongock 4.3 to 5. I added the new dependencies with the new groupId. But since we have ChangeLog and ChangeSet, should I also keep the old dependency with the old groupId? Or is it included in the new one? I tried changing import com.github.cloudyrock.mongock.ChangeLog for import io.mongock.ChangeLog but that didn't work.

    I have a situation in my Spring Boot app where I need to create default users within the MongoDB database, but I have to then invoke an external call to register the user in a cloud-based Authentication server. The call to the external Authentication server fails with an error when it makes the outbound call. I'm guessing that perhaps the ApplicationContext is not fully started and available for fully application functionality?

    When I attempt to debug the code, my injected class "AuthenticationServer" doesn't even get executed when I call "authenticationServer.register(user)" and place a breakpoint within this method. This is leading me to believe that the Spring context isn't ready or something is up with the Change Unit logic?

    Thanks Tim, could you give us more details about the error you get? Or just your method is not executing, without any error?

    Hi Tim! Mongock creates a proxy for every injected dependency in the ChangeUnit’s methods as parameters. The proxy is a mechanism to ensure Mongock has the lock acquired. If you annotate the param with @NonLockGuarded you are preventing Mongock to create a proxy for it. In your case, you can omit proxy for that service, because this SSO authentication doesn't required synchronisation. This synchronisation is critical specially for DB writes.

    Said that, that proxy only ensures the lock is acquired in every i/o method call. There is a daemon in charge of acquiring and maintaining the lock. So realistically speaking , even that SSO call is also synchronised.

    Hello, we are trying mongock examples provided in https://github.com/mongock/mongock-examples. When we build "jar" for "springboot-quickstart" example and then, run with mongock CLI, we get the following exception:

    Could you help me with this topic? Is there a licensed version or are all the features open source?.
    Thanks you!

    Hi Team, I'm trying to move legacy mongobee to mongock referred https://docs.mongock.io/v5/features/legacy-migration/index.html. during first time of deploying or performing the migration step with mongock, will it try to execute the migration on db or it just moving the data from dbchangelog to mongockChangeLog ? example if i had changeset to drop and contraint to a collection, will it try to perform this step again now, as it was already performed with mongobee migration.

    Hi, I was looking at changes for mongock/mongock#508, I noticed that we had a lot of methods which have param of Class<?> changeUnitClass in AnnotationProcessor.class which need not be there and are useful in other part of code as well. For example, I have to make changes to ChangeLogRuntimeImpl.getConstructor which again will need to repeat logic which is somewhat already there in AnnotationProcessor

    I propose to create a new domain object, something like ChangeUnitClassDO which has a field of Class<?> changeUnitClass
    So, any method that needs to do something to or on a changeUnitClass, can do for example
    changeUnitClassDO.getBeforeMethod(), changeUnitClassDO.findMethodByAnnotation(RollbackBeforeExecution.class)etc

    What do you guys think?
