Improvement: ClickHouse Keeper now supports uploading snapshots to S3

Official CH changelog text
An improvement for ClickHouse Keeper: add support for uploading snapshots to S3. S3 information can be defined inside keeper_server.s3_snapshot. #41342 (Antonio Andelic).
ClickHouse Keeper now supports uploading snapshots to S3 storage, allowing snapshot data to be stored in Amazon S3-compatible services.

Why it matters

This feature enables durable and remote storage of Keeper snapshots, improving data safety and disaster recovery by leveraging scalable S3-compatible storage. Users can centrally manage snapshots outside the local filesystem, reducing storage constraints and simplifying backup workflows.

How to use it

Configure the S3 connection details inside the keeper_server.s3_snapshot section of the ClickHouse Keeper configuration. Once set up, Keeper will upload snapshots to the defined S3 storage automatically.
