* Many improvements on ring/replication and its configuration:Alex Auvolat2021-05-281-8/+13
| | | | | | | | | | | | | | | | | | | | - Explicit "replication_mode" configuration parameters that takes either "none", "2" or "3" as values, instead of letting user configure replication factor themselves. These are presets whose corresponding replication/quorum values can be found in replication/mode.rs - Explicit support for single-node and two-node deployments (number of nodes must be at least "replication_mode", with "none" we can have only one node) - Ring is now stored much more compactly with 256*8 + n*32 bytes, instead of 256*32 bytes - Support for gateway-only nodes that do not store data (these nodes still need a metadata_directory to store the list of bucket and keys since those are stored on all nodes; it also technically needs a data_directory to start but it will stay empty unless we have bugs)
