Questions on pr_data_decision_df_met

We are having a performance issues on pr_data_decision_df_met during campaign executions with 15 Batch DF nodes and thread count of 12. We are seeing high numbers of 1) row level locks

2) PEGA0005's 3) gc buffer waits and busy buffer waits on the lob segment for pxmetrics 

Questions:

1) What is this table used for?

2) Can writing to this table be disable?

3) Is there any harm in truncating it?

@AlexM001 This table is used for storing data flow run metrics and should not be disabled. 

Truncating this table will cause issues with the data flow runs. 

 

Please create an INC on Pega support portable, then we can analyze logs from your system and give you an apt solution after understanding the actual issue.
