Expand description

Scanner for discovering SSTables in a data directory

Implementations§

Source§

impl Scanner

Source

pub fn new(data_dir: &Path, version_hint: Option<String>) -> Self

Create a new scanner for the given data directory

Source

pub fn scan(&self) -> Result<ScanResult>

Scan the data directory for SSTables

This method scans the data directory structure and discovers:

  • Keyspaces (excluding system keyspaces)
  • Tables (excluding system tables)
  • SSTable files (Data.db files)

Cassandra data directory structure is: data_dir/keyspace_name/table_name-table_id/sstable_files

Source

pub fn resolve_version( &self, _scan_result: &ScanResult, ) -> Result<Option<String>>

Resolve Cassandra version using precedence:

  1. version_hint (if provided)
  2. SSTable metadata (from Data.db headers)
  3. metadata.yml (cluster metadata)
  4. “unknown” (fallback)
