Subject [jira] [Created] (IGNITE-11125) Use alternative column instead of special _key for indexes.
Date Tue, 29 Jan 2019 12:51:00 GMT
Yury Gerzhedovich created IGNITE-11125:
------------------------------------------

             Summary: Use alternative column instead of special _key for indexes.
                 Key: IGNITE-11125
                 URL: https://issues.apache.org/jira/browse/IGNITE-11125
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Yury Gerzhedovich
            Assignee: Yury Gerzhedovich
             Fix For: 2.8


Currently we can have the same columns for inline indexes twice because in part cases use
alternative columns for another case special column _key.  To avoid duplicate the same columns
need to use alternative columns (real columns) always.

 

For example for CREATE TABLE CACHE_SQL (ID INT PRIMARY KEY, MY_VAL VARCHAR) will be used
index with two columns ID and _KEY.
