Describe history operationMetrics['materializeSourceTimeMs']

[roberta_cereda]

Hi, 

during some checks on MERGE execution , I was running the describe history command and in the operationMetrics column I noticed this information :  operationMetrics['materializeSourceTimeMs'] .

I haven't found that metric in the documentation so I am asking if anyone has already discovered what is that metric.

Regards

Roberta

If it’s specific to “materializeSourceTimeMs” then it’s “time taken to materialize source (or determine it's not needed)”
