You can combine `dataclasses` with other type annotations in many different combinations to form complex data structures.

Check the in-code annotation tips above to see more specific details.

You can also combine `dataclasses` with other Pydantic models, inherit from them, include them in your own models, etc.

**Purpose**: Test FilenameExtractor edge cases and new documentation.

**Key Test Areas**:

*   Focusing on what is best for the community.
*   Showing empathy towards other community members.

Examples of unacceptable behavior by participants include:

# Bucket Metrics

MinIO collects the following metrics at the bucket level.
Each metric includes the ``bucket`` label to identify the corresponding bucket.
Metrics may include one or more additional labels, such as the server that calculated that metric.

These metrics can be obtained from any MinIO server once per collection by using the following URL:

OkHttp attempts to balance two competing concerns:

 * **Connectivity** to as many hosts as possible. That includes advanced hosts that run the latest versions of [boringssl](https://boringssl.googlesource.com/boringssl/) and less out of date hosts running older versions of [OpenSSL](https://www.openssl.org/).
 * **Security** of the connection. This includes verification of the remote webserver with certificates and the privacy of data exchanged with strong ciphers.
