+# Fluss Rust Client
+
+## Overview
+The Fluss Rust Client is a high-performance, asynchronous library powered by the `tokio` runtime. It provides a native interface for interacting with Fluss clusters with minimal overhead.
+
+The client provides two main APIs:
+* **Admin API**: For managing databases, tables, and partitions.
+* **Table API**: For high-throughput reading (Scanners/Lookups) and writing (Writers).
+
+## Installation
+The Fluss Rust client is published to [crates.io](https://crates.io/crates/fluss-rs) as `fluss-rs`. Note that the library name for imports is `fluss`.
+
+Add the following to your `Cargo.toml`:
+
+```toml
+[dependencies]
+fluss-rs = "0.1"
+tokio = { version = "1", features = ["full"] }
+```
+
+:::tip
+This page provides a lightweight introduction to the Fluss Rust Client.
+
+For a complete and up-to-date Rust client reference, including advanced APIs and examples, see the
+[official Rust client documentation](https://github.com/apache/fluss-rust/blob/main/docs/rust-client.md).
+:::
+
+
+## Initialization
+
+The FlussConnection is the entry point for interacting with a cluster. It is thread-safe and should be reused across your application
+
+```rust
+use fluss::client::FlussConnection;
+use fluss::config::Config;
+use fluss::error::Result;
+
+#[tokio::main]
+async fn main() -> Result<()> {
+    let mut config = Config::default();
+    config.bootstrap_server = "127.0.0.1:9123".to_string();
+
+    let conn = FlussConnection::new(config).await?;
+    
+    // Obtain Admin interface
+    let admin = conn.get_admin().await?;
+    
+    Ok(())
+}
+```
+
+## Admin API
+
+The Admin interface allows you to manage the lifecycle of your data.
+
+### Creating a Table
+
+```rust
+use fluss::metadata::{DataTypes, Schema, TableDescriptor, TablePath};
+
+let schema = Schema::builder()
+.column("id", DataTypes::int())
+.column("name", DataTypes::string())
+.column("score", DataTypes::float())
+.primary_key(vec!["id"])
+.build()?;
+
+let descriptor = TableDescriptor::builder()
+.schema(schema)
+.bucket_count(3)
+.build()?;
+
+let table_path = TablePath::new("my_db", "my_table");
+admin.create_table(&table_path, &descriptor, true).await?;
+```
+
+## Table API
+
+### Writers
+
+Fluss writers use a fire-and-forget pattern. Use flush() to ensure batch persistence or await the append call for per-record acknowledgment
+
+```rust
+use fluss::row::GenericRow;
+
+let table = conn.get_table(&table_path).await?;
+let writer = table.new_append()?.create_writer()?;
+
+// Prepare a row with 3 fields
+let mut row = GenericRow::new(3);
+row.set_field(0, 1);            // id (int)
+row.set_field(1, "Alice");      // name (string)
+row.set_field(2, 95.5f32);      // score (float)
+
+// Queue the write
+writer.append(&row)?;
+
+// Ensure it is sent to the server
+writer.flush().await?;
+```
+
+#### Writing to a Primary Key Table
+
+```rust
+let table = conn.get_table(&table_path).await?;
+let upsert_writer = table.new_upsert()?.create_writer()?;
+
+let mut row = GenericRow::new(3);
+row.set_field(0, 1);            // id (PK)
+row.set_field(1, "Bob");
+row.set_field(2, 88.0f32);
+
+// Upsert logic: inserts if new, updates if ID exists
+upsert_writer.upsert(&row)?;
+upsert_writer.flush().await?;
+```
+
+### Scanner
+
+To read data, create a LogScanner. The poll method returns ScanRecords, which requires nested iteration.
+
+```rust
+use std::time::Duration;
+use fluss::client::EARLIEST_OFFSET;
+
+let mut scanner = table.new_scan().create_log_scanner()?;
+scanner.subscribe(0, EARLIEST_OFFSET).await?;
+
+loop {
+    let records = scanner.poll(Duration::from_secs(5)).await?;
+    
+    // Iterate through bucket groups
+    for (_bucket, bucket_records) in records.records_by_buckets() {
+        for record in bucket_records {
+            let row = record.row();
+            println!("Received row: {:?} at offset {}", row, record.offset());
+        }
+    }
+}
+```
+
+### Lookup
+
+Perform point lookups on Primary Key tables using a key row.
+
+```rust
+let mut lookuper = table.new_lookup()?.create_lookuper()?;
+
+// Key row must only contain Primary Key columns
+let mut key = GenericRow::new(1);
+key.set_field(0, 1); 
+
+let result = lookuper.lookup(&key).await?;
+if let Some(row) = result.get_single_row()? {
+    println!("Found: id={}, name={}", row.get_int(0), row.get_string(1));
+}
+```
+
+## Type Mapping
+
+The Rust client maps Fluss types to Rust types as follows:
+
+| Fluss Type | Rust Type | Method Example |
+|-----------|-----------|----------------|
+| `INT` | `i32` | `row.get_int(idx)` |
+| `BIGINT` | `i64` | `row.get_long(idx)` |
+| `STRING` | `&str` | `row.get_string(idx)` |
+| `BOOLEAN` | `bool` | `row.get_boolean(idx)` |
+| `FLOAT` | `f32` | `row.get_float(idx)` |
+| `DOUBLE` | `f64` | `row.get_double(idx)` |
+| `BYTES` | `&[u8]` | `row.get_bytes(idx)` |
+
