PG_TOTAL_USER_RESOURCE_INFO

PG_TOTAL_USER_RESOURCE_INFO displays the resource usage of all users. Only administrators can query this view. This view is valid only if use_workload_manager is set to on.

Table 1 PG_TOTAL_USER_RESOURCE_INFO columns

Name

Type

Description

username

name

Username

used_memory

integer

Memory size used by a user, in (MB).

  • DN: The memory used by users on the current DN is displayed.
  • CN: The total memory usage of users on all DNs is displayed.

total_memory

integer

Memory used by the resource pool (MB). 0 indicates that the available memory is not limited and depends on the maximum memory available in the database (max_dynamic_memory). A calculation formula is as follows:

total_memory = max_dynamic_memory * parent_percent * user_percent

CN: The sum of maximum available memory on all DNs is displayed.

used_cpu

double precision

Number of CPU cores in use. Only the CPU usage of complex jobs in the non-default resource pool is collected, and the value is the CPU usage of the related cgroup.

total_cpu

integer

Total number of CPU cores of the Cgroup associated with a user on the node

used_space

bigint

Used permanent table storage space (unit: KB)

total_space

bigint

Available permanent table storage space (unit: KB) The value -1 indicates no limit.

used_temp_space

bigint

Used temporary table storage space (unit: KB)

total_temp_space

bigint

Available temporary table storage space (unit: KB) The value -1 indicates no limit.

used_spill_space

bigint

Space used for operator spill, in KB.

total_spill_space

bigint

Available space for operator spill, in KB. The value -1 indicates no limit.

read_kbytes

bigint

On a CN, it indicates total number of bytes read by a user's complex jobs on all DNs in the last 5 seconds. The unit is KB.

On a DN, it indicates the total number of bytes read by a user's complex jobs from the instance startup time to the current time. The unit is KB.

write_kbytes

bigint

On a CN, it indicates total number of bytes written by a user's complex jobs on all DNs in the last 5 seconds.

On a DN, it indicates the total number of bytes written by a user's complex jobs from the instance startup time to the current time. The unit is KB.

read_counts

bigint

CN: total number of read times of a user's complex jobs on all DNs in the last 5 seconds.

DN: total number of read times of a user's complex jobs from the instance startup time to the current time.

write_counts

bigint

CN: total number of write times of a user's complex jobs on all DNs in the last 5 seconds.

DN: total number of write times of a user's complex jobs from the instance startup time to the current time.

read_speed

double precision

On a CN, it indicates the average read rate of a user's complex jobs on a single DN in the last 5 seconds, in KB/s.

On a DN, it indicates the average read rate of a user's complex jobs on the DN in the last 5 seconds, in KB/s.

write_speed

double precision

On a CN, it indicates the average write rate of a user's complex jobs on a single DN in the last 5 seconds, in KB/s.

On a DN, it indicates the average write rate of a user's complex jobs on the DN in the last 5 seconds, in KB/s.
