1.keep more event logs for dc_tuple_mover_events.
select SET_DATA_COLLECTOR_POLICY('TupleMoverEvents', '1000', '100000'); 
default: 1000KB kept in memory, 10000KB kept on disk.

2.keep more event logs for dc_errors.
select SET_DATA_COLLECTOR_POLICY('Errors', '1000', '100000');  
default: 1000KB kept in memory, 10000KB kept on disk.

3.PARAMETER MaxClientSessions: for concurrent queries and data loading jobs

Maximum desired size of an EE block (used to move tuples between operators), actual block size be larger (must have capacity for at least 2 rows)
 
7.
SELECT SET_CONFIG_PARAMETER('ParallelizeLocalSegmentLoad', '1');
default: 1 .If true use a DT per local segment, even when sorting
