Is there a ballpark for how long async SOQL queries on big objects take? I know i depends on the size of the data, but are we talking minutes vs hours vs days?
whats the amount of data you are referring to? (i personally am clueless)– gllsSep 23, 2019 at 19:35
Potentially upto 40 million rows– hamayounSep 23, 2019 at 20:51
40 million rows is a relatively small data set for big objects, so should execute relatively quickly.
A presentation by Salesforce had a dataset with 1 Billion order line items, it was suggested that an aggregate query on that dataset would take around 10 minutes.
So I expect your query would run more quickly than that.
