Explanation
When the connector creates a temporary work table (TWT), the connector tries to replicate
the distribution mechanism of the target table. This message is logged when the target table
uses hash distribution to organize the database table, and one or more distribution key columns
are missing from the link. Because the connector cannot use hash distribution, the connector
uses random distribution for the TWT that it creates.
User response
(Optional) If you want the TWT to match the distribution of the target table, make sure all
distribution key columns are present on the link and that their data types match the data
types of the columns in the target table.
