             Summary: CREATE TABLE: add multithreaded tests
                 Key: IGNITE-5465
                 URL: https://issues.apache.org/jira/browse/IGNITE-5465
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
            Assignee: Alexander Paschenko
             Fix For: 2.1


We need to add multithreaded tests for {{CREATE TABLE}} and {{DROP TABLE}} commands in a similar way as we did that for indexes ({{DynamicIndexAbstractConcurrentSelfTest}}. 

Let's test the following case:
- Create and drop of the same several tables from different threads and different nodes (including a client). 
- Success criteria: nothing hangs and in the end table/cache is either doesn't exist, or exists and operational (verify through DML and SELECT queries).

AFAIK there is a bug in how we start caches dynamically, so honestly there is a high chance that this test will not work as expected due to non-SQL bugs. So at the very least we must ensure that it either works, or doesn't work due to a problem outside of DDL engine.
