> Key: IGNITE-13518
> URL: https://issues.apache.org/jira/browse/IGNITE-13518
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.8.1
> Reporter: Alexand Polyakov
> Priority: Major
> Attachments: Ignite13518CaseAdd.java
>
>
> If a new node with a modified configuration cache is connected, the
> configuration is merged and a new column is added. if the cluster is
> restarted with a new cache configuration, the changes are ignored and the
> column is not added
> 1. you need to determine whether to allow changing the static cache
> configuration or not to allow it
> 2. the behavior should be the same (restart cluster, join node)
> 3. the behavior is not described in the documentation
> 4. How static cache configuration interacts with dynamic changes from SQL?
> 5. Export/import database schema
> 6. There are no messages in the application logs about changing the cache
> configuration (or about a ban based on the result of point 1)
> 7. If the configuration can be changed, what should I do with the fields that
> are missing in the new version of the configuration - delete column? if they
> were added using SQL
