This patch series aims to add S3 compatible object stores as storage backend for PBS datastores. A PBS local cache store using the regular datastore layout is used for faster operation, bypassing requests to the S3 api when possible. Further, the local cache store allows to keep frequently used chunks and is used to avoid expensive metadata updates on the object store, e.g. by using local marker file during garbage collection. Backups are created by upload chunks to the corresponding S3 bucket, while keeping the index files in the local cache store, on backup finish, the snapshot metadata are persisted to the S3 storage backend. Snapshot restores read chunks preferably from the local cache store, downloading and insterting them if not present from the S3 object store. Listing and snapsoht metadata operation currently rely soly on the local cache store. Currently chunks use a 1:1 mapping to S3 objects. An advanced packing mechanism for chunks to significantly reduce the number of api requests and therefore be more cost effective will be implemented as followup patches. Most notably changes since version 3 of the patches: - Rebased onto current master, fixed incompatibilities with upgraded dependencies - Added method to uri decode s3 object keys, as they are required in order to download contents to a local store - Added api endpoint to allow resyncing of the datastore contents to the local cache store, introducing a new maintenance mode s3-refresh to guarantee consistency. Most notably changes since RFC version 2 of the patches (thanks @Lukas for feedback): - Extend S3 client implementation to also support path style bucket addressing. - Keep bucket name as config option for the datastore, allowing more flexible reuse of a configured S3 client. - Use the datastore name as additional object key prefix to allow for multiple datastores on the same bucket. - Allow bucket and region templating in S3 endpoint, making this more flexible with respect to possible DNS records. - Rework datastore create window to be less overloaded. - Drop dead code in the S3 client implementation, since tagging and object copying is currently not required. - Fix missing locking when deleting chunks from s3 store during garbage collection, avoiding possible chunk loss for concurrent backups. - Remove chunks from LRU cache when deleting chunks during garbage collection, avoiding possible chunk loss for concurrent backups. - Add dedicated types for object prefix and relative s3 key paths to avoid misuse. - Use more fitting icon for S3 client.
