             Summary: SQL COPY command: implement NULL escape sequence handling
                 Key: IGNITE-7539
                 URL: https://issues.apache.org/jira/browse/IGNITE-7539
             Project: Ignite
          Issue Type: Improvement
            Reporter: Kirill Shirokov


There should be a way to specify NULL field value in a file, which we import via COPY command.

A popular solution among vendors for CSV format is to have a special escape sequence for a
NULL value in a field: \N for example.

We need to have a possibility to enable/disable null escape sequence handling for all fields
or on per-field basis.
