-----------------------------------
> SQL: make sure CREATE INDEX doesn't corrupt the cluster
> -------------------------------------------------------
>
> Key: IGNITE-7971
> URL: https://issues.apache.org/jira/browse/IGNITE-7971
> Project: Ignite
> Issue Type: Task
> Components: sql
> Affects Versions: 2.4
> Reporter: Vladimir Ozerov
> Priority: Major
> Fix For: 2.6
>
>
> Consider the following scenario:
> 1) Define query entity with field {{X}} of type {{int}}
> 2) Start two nodes
> 3) Put an object with field {{X}} of type {{int}} to node 1
> 4) Put an object with field {{X}} of type {{*String*}} to node 2
> 5) Invoke {{CREATE INDEX}} on that field
> We need to investigate what would happen. In the worst case index creation
> will fail on node 2. But it seems that we do not perform any rollback on
> server nodes in that case, only client node is informed about the problem. If
> it is so, we need to answer the following questions:
> 1) What would happen to subsequent SQL queries initiated from different
> nodes. Will they work?
> 2) What would happen to data in case of restarts with persistence?
