We now include the documentations partial about custom conversions that explains default converter registrations, overrides and system setting timezone-sensitivity.
Spring Data MongoDB uses the @Sharded annotation to identify entities stored in sharded collections.
The shard key consists of a single or multiple properties present in every document within the target collection, and is used to distribute them across shards.
Spring Data MongoDB will do best effort optimisations for sharded scenarios when using repositories by adding required shard key information, if not already present, to replaceOne filter queries when upserting entities. This may require an additional server round trip to determine the actual value of the current shard key.
By setting @Sharded(immutableKey = true) no attempt will be made to check if an entities shard key changed.
Please see the MongoDB Documentation for further details and the list below for which operations are eligible to auto include the shard key.
* Reactive/CrudRepository.save(...)
* Reactive/CrudRepository.saveAll(...)

Adapt to changes in commons. Add functional create method to MongoCustomConversions. Update Javadoc and reference documentation. Truncate precision for Java 11 build compatibility in tests.
Original pull request: #810.
We now use the MongoDB Java driver InstantCodec instead of a dedicated converter. Other java.time types like LocalDate use a different zone offset when writing values which can lead to unexpected behavior. Therefore we added configuration options to MongoCustomConversions that allow to tell the conversion sub system which approach to use when writing those kind of types.

Move from AsyncInputStream handling to Publisher for GridFS.
UUID types require additional configuration setup to prevent errors while processing legacy (type 3) binary types. We still use type 3 as default but allow codec configuration for type 4 via Java and XML configuration.
Updated migration guide.
