Struct Rocksdb 

pub struct Rocksdb { /* private fields */ }

RocksDB service support.

Capabilities

This service can be used to:

• create_dir
• stat
• read
• write
• delete
• copy
• rename
• list
• presign

Note

OpenDAL will build rocksdb from source by default.

To link with existing rocksdb lib, please set one of the following:

• ROCKSDB_LIB_DIR to the dir that contains librocksdb.so
• ROCKSDB_STATIC to the dir that contains librocksdb.a

If the version of RocksDB is below 6.0, you may encounter compatibility issues. It is advisable to follow the steps provided in the INSTALL file to build rocksdb, rather than relying on system libraries that may be outdated and incompatible.

Configuration

• root: Set the working directory of OpenDAL
• datadir: Set the path to the rocksdb data directory

You can refer to RocksdbBuilder’s docs for more information.

Example

Via Builder

use anyhow::Result;
use opendal::services::Rocksdb;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Rocksdb::default()
        .datadir("/tmp/opendal/rocksdb");

    let op: Operator = Operator::new(builder)?.finish();
    Ok(())
}
