# Creating a profile and setting it

## Example

To create an `ExecutionProfile` and attach it as default for `Session`:

```rust
use scylla::client::session::Session;
use scylla::client::session_builder::SessionBuilder;
use scylla::statement::Consistency;
use scylla::client::execution_profile::ExecutionProfile;

let profile = ExecutionProfile::builder()
    .consistency(Consistency::LocalOne)
    .request_timeout(None) // no request timeout
    .build();

let handle = profile.into_handle();

let session: Session = SessionBuilder::new()
    .known_node("127.0.0.1:9042")
    .default_execution_profile_handle(handle)
    .build()
    .await?;
```

## Example

To create an `ExecutionProfile` and attach it to a `Statement`:

```rust
use scylla::statement::unprepared::Statement;
use scylla::statement::Consistency;
use scylla::client::execution_profile::ExecutionProfile;
use std::time::Duration;

let profile = ExecutionProfile::builder()
    .consistency(Consistency::All)
    .request_timeout(Some(Duration::from_secs(30)))
    .build();

let handle = profile.into_handle();

let mut query1 = Statement::from("SELECT * FROM ks.table");
query1.set_execution_profile_handle(Some(handle.clone()));

let mut query2 = Statement::from("SELECT pk FROM ks.table WHERE pk = ?");
query2.set_execution_profile_handle(Some(handle));
```

## Example

To create an `ExecutionProfile` based on another profile:

```rust
use scylla::statement::Consistency;
use scylla::client::execution_profile::ExecutionProfile;
use std::time::Duration;

let base_profile = ExecutionProfile::builder()
    .request_timeout(Some(Duration::from_secs(30)))
    .build();

let profile = base_profile.to_builder()
    .consistency(Consistency::All)
    .build();

```
