## Summary of Changes
Hello @NoahStapp, I'm Gemini Code Assist[^1]! I'm currently reviewing this
pull request and will post my feedback shortly. In the meantime, here's a
summary to help you and other reviewers quickly get up to speed!
This pull request finalizes the integration of MongoDB's wrapping client
library specification within Apache Beam's MongoDB I/O connector. The core
purpose is to ensure that Beam's version information is consistently
transmitted during the MongoDB connection handshake, which significantly
enhances server-side logging capabilities for better operational insights.
Additionally, the changes include refactoring the `_MongoSource` class to
manage client connections more efficiently by reusing a single `MongoClient`
instance across operations.
### Highlights
* **MongoDB Handshake Metadata**: This pull request completes the
implementation of MongoDB's wrapping client library specification, ensuring
that Apache Beam's version details are consistently included in the MongoDB
connection handshake. This enhancement allows server-side logs to capture
valuable metadata about the connecting Beam application, facilitating better
log analysis and differentiation of connections from various applications.
* **Refactoring MongoDB Client Usage in _MongoSource**: The `_MongoSource`
class has been refactored to optimize its interaction with MongoDB. Instead of
creating a new `MongoClient` instance for each operation (such as
`estimate_size`, `read`, or `_get_split_keys`), it now consistently utilizes a
single `self.client` instance, improving efficiency and resource management.
* **Consistent DriverInfo for _MongoSink**: The `_MongoSink` class now
explicitly passes `DriverInfo("Apache Beam", beam.__version__)` during the
initialization of its `MongoClient` instance within both its `write` method and
`__enter__` context manager. This ensures that the Beam version information is
correctly propagated to MongoDB for write operations as well.
