Considerations
When enable_record_trace_log is set to False, the trace_log_sampling_interval parameter determines the time interval for printing slow query and allowlist information.

Set the time interval for periodically printing trace log information to 10ms.
obclient> ALTER SYSTEM SET trace_log_sampling_interval='10ms';
