SQL401E - Temporary distributed result table &1 was created because table &2 was broadcast

SQL401E
Message Text: Temporary distributed result table &1 was created because table &2 was broadcast
Cause Text: Temporary distributed result table was created to contain the intermediate results of the query. Data from a distributed table in the query was broadcast to all nodes.
Recovery Text: Generally, a table is broadcast when join columns do not match the partitioning keys of either table being joined or the join operator is not an equal operator. When a table is broadcast the query is processed in multiple steps and processed in parallel. A temporary distributed result table is required to contain the intermediate results for each step.

For more information about processing of distributed tables, refer to the Distributed Database Programming information.
