# Pipelining
Pipelining allows you to send multiple queries to the server without waiting for the response of each query. This reduces round-trip latency and improves throughput.
## Basic Pipelining
```rust,ignore
// Prepare statements outside the pipeline
let stmts = conn.prepare_batch(&[
"SELECT id, name FROM users WHERE active = $1",
"SELECT COUNT(*) FROM users",
])?;
let (active_users, count) = conn.pipeline(|p| {
// Queue executions
let t1 = p.exec(&stmts[0], (true,))?;
let t2 = p.exec(&stmts[1], ())?;
// Sync sends all queued operations
p.sync()?;
// Claim results in order
let active_users: Vec<(i32, String)> = p.claim_collect(t1)?;
let count: Vec<(i64,)> = p.claim_collect(t2)?;
Ok((active_users, count))
})?;
```
## Pipeline Benefits
- **Reduced Latency**: Multiple queries are sent in a single network round trip
- **Higher Throughput**: Server can process queries while client sends more
- **Batch Operations**: Efficient for bulk inserts or updates
