> Components: io-py-mongodb

> Reporter: Corvin Deboeser

> Priority: P2
> Labels: stale-assigned
>
> When using MongoDBIO on a large collection with large documents on average,
> then the split vector command results in a lot of splits if the desired
> bundle size is small. In extreme cases, the response from the split vector
> command can be larger than 16mb which is not supported by pymongo / MongoDB:
> {{pymongo.errors.ProtocolError: Message length (33699186) is larger than
> server max message size (33554432)}}
>
> Environment: Was running this on Google Dataflow / Beam Python SDK 2.20.
