PV_INSTANCE_TIME¶
PV_INSTANCE_TIME collects statistics on the running time of processes and the time consumed in each execution phase, in microseconds.
PV_INSTANCE_TIME records time consumption information of the current node. The time consumption information is classified into the following types:
DB_TIME: effective time spent by jobs in multi-core scenarios
CPU_TIME: CPU time spent
EXECUTION_TIME: time spent within executors
PARSE_TIME: time spent on parsing SQL statements
PLAN_TIME: time spent on generating plans
REWRITE_TIME: time spent on rewriting SQL statements
PL_EXECUTION_TIME: execution time of the PL/pgSQL stored procedure
PL_COMPILATION_TIME: compilation time of the PL/pgSQL stored procedure
NET_SEND_TIME: time spent on the network
DATA_IO_TIME: I/O time spent
