username |
name |
Username used for connecting to the backend |
application_name |
text |

resource_pool |
name |
Resource pool used by the user |
control_group |
text |
Cgroup used by the statement |
estimate_memory |

integer |
Average memory usage during statement execution (unit: MB) |
memory_skew_percent |
integer |
Memory usage skew of the statement among DNs |
spill_info |
text |
Statement spill information on all DNs.
|
min_spill_size |
integer |
Minimum spilled data among all DNs when a spill occurs (unit: MB; default value: 0) |
max_spill_size |
integer |
Maximum spilled data among all DNs when a spill occurs (unit: MB; default value: 0) |
average_spill_size |
integer |
Average spilled data among all DNs when a spill occurs (unit: MB; default value: 0) |
spill_skew_percent |
integer |
DN spill skew when a spill occurs |
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 DNs |
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. It is counted by ones in a column-store table and by ten thousands in a row-store table. |
max_peak_iops |
integer |
Maximum peak IOPS of the statement across all DNs. It is counted by ones in a column-store table and by ten thousands in a row-store table. |
average_peak_iops |
integer |
Average peak IOPS of the statement across all DNs. It is counted by ones in a column-store table and by ten thousands in a row-store table. |
iops_skew_percent |
integer |
I/O skew of the statement among DNs |
