[WARNING] The InitialSync thread
thread_ID
for table
table_name
:
Average processing time of the SQL statement during the last performance statistics print interval is
percent_number
percent slower than the average processing time since the InitialSync had started.
This warning indicates a performance problem that causes a slower respond of the source or target database during the last performance statistics print interval. If this performance degradation is caused by legitimate circumstances, such as temporary high load of the source or target database, ignore this warning. Otherwise, this warning indicates that the database workload is too high for the resources that are allocated for the database.
Perform one of the following actions:
  • Ignore the warning.
  • Decrease the number of the InitialSync threads in the replication configuration.
  • Increase the resources that are allocated to the source or target database.
You can configure settings for performance degradation warnings by using the following runtime parameters:
  • apply.performance_degradation_warning_percentage
  • apply.performance_degradation_warning_step
  • apply.performance_degradation_warning_threshold
  • apply.print_statistics_interval
