[GitHub] [iceberg] liuml07 opened a new pull request #4478: Spark: Support identifier fields when creating table with SQL

[GitBox <gi...@apache.org>]

liuml07 opened a new pull request #4478:
URL: https://github.com/apache/iceberg/pull/4478


   Currently Spark SQL does not allow user to specify 'identifier-fields' when creating table. This is a PoC effort.
   
   ```sql
   CREATE TABLE t1(
           id BIGINT NOT NULL,
           name STRING NOT NULL,
           data STRING)
   USING iceberg
   TBLPROPERTIES ('identifier-fields'='id,name')
   ```
   
   After this, we can add support for other engines like Hive easily.

   Options is recommended. TBLPROPERTIES does not match the use keyword
