Wed Sep 14 19:07:07 2022, PJCS, INFO : Three Merger Statistics explained
|
There are three Merger statistics that can be used to better understand how the data flow through the Merger system is proceeding.
Two are from the Link task and one is from the Merger.They are all "No data buffers avaliable" with #1, #2, #3 at the end.
#1: This is incremented when the Link task has a data item to put in the queue for the Merge process but there is no room. |
