Expand description
Database config options.
Fields§
§path: PathBuf
Database directory path.
By default, it is a subdirectory inside the data directory.
cache_size: Option<usize>
The capacity of RocksDB cache, which caches uncompressed data blocks, indexes and filters, default is 128MB
options: HashMap<String, String>
Provide RocksDB options.
More details can be found in the official tuning guide.
options_file: Option<PathBuf>
Provide an options file to tune RocksDB for your workload and your system configuration.
More details can be found in the official tuning guide.
Implementations§
source§impl Config
impl Config
sourcepub fn adjust<P: AsRef<Path>>(
&mut self,
root_dir: &Path,
data_dir: P,
name: &str
)
pub fn adjust<P: AsRef<Path>>( &mut self, root_dir: &Path, data_dir: P, name: &str )
Canonicalizes paths in the config options.
If self.path
is not set, set it to data_dir / name
.
If self.path
or self.options_file
is relative, convert them to absolute path using
root_dir
as current working directory.
