Hvad er adfærden ved at indstille timeout i aggregeringspipeline-udførelse i MongoDB Java Driver?

Ok, jeg har det. Hvis eksekveringen af ​​aggregeringspipelinen overskrider tiden udtrykt med metoden maxTime en com.mongodb.MongoExecutionTimeoutException er smidt.

Undtagelsens stacktrace er nøjagtigt følgende:

com.mongodb.MongoExecutionTimeoutException: operation exceeded time limit
