Release Notes

MongoDB Connector for Spark 10.1.1

Corrected a bug in which aggregations including the $collStats pipeline stage did not return a count field for Time Series collections.

Support for Scala 2.13.
Support for micro-batch mode with Spark Structured Streaming.
Support for BSON data types.
Improved partitioner support for empty collections.
Option to disable automatic upsert on write operations.
Improved schema inference for empty arrays.
Support for null values in arrays and lists. The Connector now writes these values to MongoDB instead of throwing an exception.
