Subject: [pbs-devel] [PATCH proxmox-backup v6 31/37] api: reader: use local datastore cache on s3 backend chunk fetching
Date: Tue, 8 Jul 2025 19:01:08 +0200 [thread overview]
Message-ID: <20250708170114.1556057-41-c.ebner@proxmox.com> (raw)
In-Reply-To: <20250708170114.1556057-1-c.ebner@proxmox.com>
Take advantage of the local datastore filesystem cache for datastores
backed by an s3 object store in order to reduce number of requests
and latency, and increase throughput.
Also, reducing the number of requests is cost beneficial for S3 object
stores charging for fetching of objects.
