An sstable can be in one of several states -- normal, quarantined, staging, uploading. Right now this "state" is hard-wired into sstable's path, e.g. quarantined sstable would sit in e.g. /var/lib/data/ks-cf-012345/quarantine/ directory. Respectively, there's a bunch of directory names constexprs in sstables.hh defining each "state". Other than being confusing, this approach doesn't work well with S3 backend. Additionally, there's snapshot subdir that adds to the confusion, because snapshot is not quite a state. This PR converts "state" from constexpr char* directories names into a enum class and patches the sstable creation, opening and state-changing API to use that enum instead of parsing the path. refs: #13017 refs: #12707 Closes #14152 * github.com:scylladb/scylladb: sstable/storage: Make filesystem storage with initial state sstable: Maintain state sstable: Make .change_state() accept state, not directory string sstable: Construct it with state sstables_manager: Remove state-less make_sstable() table: Make sstables with required state test: Make sstables with upload state in some cases tools: Make sstables with normal state table: Open-code sstables making streaming helpers tests: Make sstables with normal state by default sstable_directory: Make sstable with required state sstable_directory: Construct with state distributed_loader: Make sstable with desired state when populating distributed_loader: Make sstable with upload state when uploading sstable: Introduce state enum sstable_directory: Merge verify and g.c. calls distributed_loader: Merge verify and gc invocations sstable/filesystem: Put underscores to dir members sstable/s3: Mark make_s3_object_name() const sstable: Remove filename(dir, ...) method
