Subject [jira] [Created] (IGNITE-7545) SQL COPY command: implement duplicate handling strategy
Date Fri, 26 Jan 2018 09:54:00 GMT

---------------------------------------

             Summary: SQL COPY command: implement duplicate handling strategy
                 Key: IGNITE-7545
                 URL: https://issues.apache.org/jira/browse/IGNITE-7545
             Project: Ignite
          Issue Type: Improvement
          Components: sql
    Affects Versions: 2.4
            Reporter: Kirill Shirokov


The SQL COPY command should have user-configurable policy of handling duplicate records:

{noformat}
COPY
    ...
     [(REPLACE | IGNORE| ABORT ON [<max-error-number>])) DUPLICATE KEYS]
{noformat}

This handling might be not available for some backends (e.g., streamer).
