GLOBAL_STATEMENT_COMPLEX_HISTORY

Displays workload management information about completed jobs executed on each node, as described in Table 1.

**Table 1** GLOBAL_STATEMENT_COMPLEX_HISTORY columns
Name	Type	Description

min_dn_time	bigint	Minimum execution time of the statement across all DNs (unit: ms).
max_dn_time	bigint	Maximum execution time of the statement across all DNs (unit: ms).
average_dn_time	bigint	Average execution time of the statement across all DNs (unit: ms).
dntime_skew_percent	integer	Execution time skew of the statement among each DN.
min_cpu_time	bigint	Minimum CPU time of the statement across all DNs (unit: ms).
max_cpu_time	bigint	Maximum CPU time of the statement across all DNs (unit: ms).
total_cpu_time	bigint	Total CPU time of the statement across all DNs (unit: ms).
cpu_skew_percent	integer	CPU time skew of the statement among DNs.
min_peak_iops	integer	Minimum peak IOPS of the statement across all DNs (unit: 10 thousands per second).
max_peak_iops	integer	Maximum peak IOPS of the statement across all DNs (unit: 10 thousands per second).
average_peak_iops	integer	Average peak IOPS of the statement across all DNs (unit: 10 thousands per second).
iops_skew_percent	integer	I/O skew across DNs.
warning	text	Warning. The following warnings and warnings related to Optimizing SQL Self-Diagnosis are displayed: Spill file size large than 256MB Broadcast size large than 100MB Early spill Spill times is greater than 3 Spill on memory adaptive Hash table conflict
queryid	bigint	Internal query ID used for statement execution.
