GLOBAL_STATEMENT_COMPLEX_RUNTIME

GLOBAL_STATEMENT_COMPLEX_RUNTIME displays load management records of jobs that are being executed by the current user on each node. The current feature is a lab feature. Contact Huawei technical support before using it.

Table 1 GLOBAL_STATEMENT_COMPLEX_RUNTIME columns

Name

Type

Description

datid

oid

OID of the database that the backend is connected to

dbname

name

Name of the database that the backend is connected to

schemaname

text

Schema name

nodename

text

Node name

username

name

Username used for connecting to the backend

application_name

text

Name of the application connected to the backend

client_addr

inet

IP address of the client connected to the backend. If this column is null, it indicates either the client is connected via a Unix socket on the server or this is an internal process, such as autovacuum.

client_hostname

text

Host name of the connected client, as reported by a reverse DNS lookup of client_addr. This column will be non-null only for IP connections and only when log_hostname is enabled.

client_port

integer

TCP port number that the client uses for communication with this backend (-1 if a Unix socket is used)

query_band

text

Job type, which is specified by the GUC parameter query_band. The default value is a null string.

pid

bigint

Thread ID of the backend

block_time

bigint

Block time before the statement is executed (unit: ms)

start_time

timestamp with time zone

Time when the statement starts to be executed

duration

bigint

Duration that a statement has been executed (unit: ms)

estimate_total_time

bigint

Estimated execution time of the statement (unit: ms)

estimate_left_time

bigint

Estimated remaining execution time of the statement (unit: ms)

enqueue

text

Resource status in workload management. The current feature is a lab feature. Contact Huawei technical support before using it.

resource_pool

name

Resource pool used by the user

control_group

text

Cgroup used by the statement

estimate_memory

integer

Estimated memory used by the statement (unit: MB).

min_peak_memory

integer

Minimum memory peak of the statement across the database nodes (unit: MB)

integer

Average spilled data among database nodes when a spill occurs (unit: MB) (default value: 0)

spill_skew_percent

integer

Database node spill skew when a spill occurs

min_dn_time

bigint

Minimum execution time of the statement across the database nodes (unit: ms)
