This client provides foundational capabilities for table management and log streaming operations, enabling developers to explore Fluss within Rust ecosystems. + +## Quick-Start + +### Step1 Start Fluss cluster +#### Requirements +Fluss runs on all UNIX-like environments, e.g. Linux, Mac OS X. Before you start to setup the system, make sure you have the following software installed on your test machine: + +Java 17 or higher (Java 8 and Java 11 are not recommended) +If your cluster does not fulfill these software requirements you will need to install/upgrade it. + +Fluss requires the JAVA_HOME environment variable to be set on all nodes and point to the directory of your Java installation. + +#### Fluss Setup +Go to the [downloads](https://fluss.apache.org/downloads/) page and download the Fluss-0.6.0. Make sure to pick the Fluss package matching your Java version. After downloading the latest release, extract it: +```shell +tar -xzf fluss-0.7-SNAPSHOT-bin.tgz +cd fluss-0.7-SNAPSHOT/ +``` +You can start Fluss local cluster by running the following command: +```shell +./bin/local-cluster.sh start +``` +After that, the Fluss local cluster is started. + +### Run Provided Example +Only supports Linux or macOs. You will need to [install Rust](https://www.rust-lang.org/tools/install) firstly. + +After that, go the project directory, build it and run the example: +```shell +cargo build --example example-table --release +cd target/release/examples +./example-table +``` +The example code is as follows: +```rust +#[tokio::main] +pub async fn main() -> Result<()> { + // 1: create the table; + let mut args = Args::default(); + args.bootstrap_server = "127.0.0.1:9123".to_string(); + let conn_config = ConnectionConfig::from_args(args); + let conn = FlussConnection::new(conn_config).await; + + let admin = conn.get_admin(); + + let table_descriptor = TableDescriptor::builder() + .schema( + Schema::builder() + .column("c1", DataTypes::int()) + .column("c2", DataTypes::string()) + .build(), + ) + .build(); + + let table_path = TablePath::new("fluss".to_owned(), "rust_test".to_owned()); + + admin + .create_table(&table_path, &table_descriptor, true) + .await + .unwrap(); + + // 2: get the table + let table_info = admin.get_table(&table_path).await.unwrap(); + print!("Get created table:\n {}\n", table_info); + + // let's sleep 2 seconds to wait leader ready + thread::sleep(Duration::from_secs(2)); + + // 3: append log to the table + let table = conn.get_table(&table_path).await; + let append_writer = table.new_append().create_writer(); + let batch = record_batch!(("c1", Int32, [1, 2, 3, 4, 5, 6]), ("c2", Utf8, ["a1", "a2", "a3", "a4", "a5", "a6"])).unwrap(); + append_writer.append(batch).await?; + println!("Start to scan log records......"); + // 4: scan the records + let log_scanner = table.new_scan().create_log_scanner(); + log_scanner.subscribe(0, 0).await; + + loop { + let scan_records = log_scanner.poll(Duration::from_secs(10)).await?; + println!("Start to poll records......"); + for record in scan_records { + let row = record.row(); + println!( + "{{{}, {}}}@{}", + row.get_int(0), + row.get_string(1), + record.offset() + ); + } + } + Ok(()) +} +``` + +You can change it according to your needs, have fun! + +#### Clear environment +Then, stop your Fluss cluster. Go to your Fluss home, stop it via the following commands: +```shell +./bin/local-cluster.sh stop +``` + + +## License + +Licensed under the [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0) \ No newline at end of file
