The citibike.trips collection contains about 2 million documents with average size 440 bytes.
The following queries against the start and end station location fields caused the Compass schema analysis to hang the user interface.
{'start station location': {$geoWithin: { $centerSphere: [ [ -73.98475067347545, 40.73712494487114 ], 0.0013784387806381328 ]}}}
{'end station location': {$geoWithin: { $centerSphere: [ [ -73.98475067347545, 40.73712494487114 ], 0.0013784387806381328 ]}}}
The following query causes the schema analysis to take longer than 10 seconds and then freeze about in about two thirds of my tests.
{tripduration: {$gte: 60, $lt: 50010}}
Neither the DevTools nor "DEBUG=*" command line outputs showed any subsequent output when the agg pipeline times out.
I captured the following from the Atlas real time tab.
