### Batch queries

_TODO: rework this section_

CDRS `Session` supports batching few queries in a single request to Apache Cassandra via implementing `cdrs_tokio::query::BatchExecutor` trait:

```rust
// batch two queries
use cdrs_tokio::query::{BatchQueryBuilder, QueryBatch};

let mut queries = BatchQueryBuilder::new();
queries = queries.add_query_prepared(&prepared_query);
queries = queries.add_query("INSERT INTO my.store (my_int) VALUES (?)", query_values!(1 as i32));
session.batch_with_params(queries.finalyze());

// batch queries with tracing and warning information
use cdrs_tokio::query::{BatchQueryBuilder, QueryBatch};

let with_tracing = true;
let with_warnings = true;
let mut queries = BatchQueryBuilder::new();
queries = queries.add_query_prepared(&prepared_query);
queries = queries.add_query("INSERT INTO my.store (my_int) VALUES (?)", query_values!(1 as i32));
session.batch_with_params_tw(queries.finalyze(), with_tracing, with_warnings);
```
