| Description |
|
DocumentSourceCursor batch size was changed from 4MB to 16MB for MongoDB 3.4 as part of a broader effort to unify user request batch size at 16MB under Testing across our aggregation micro-benchmarks shows a 4MB DocumentSourceCursor batch size restores previous performance across affected tests and does not penalize tests that may benefit from the batching behavior. |
