Hello @Scott_Weiner,
What are you sorting on? Your aggregation doesn’t show any sort operation. Also, see Aggregation $sort Stage and Memory, and it says:
The
$sortstage has a limit of 100 megabytes of RAM. By default, if the stage exceeds this limit,$sortwill produce an error. To allow for the handling of large datasets, set theallowDiskUseoption totrueto enable$sortoperations to write to temporary files.
