Batched commands

Multiple records can be read in a single batch call.

let bins = ["name", "age"];
let mut batch_reads = vec![];
for i in 0..10 {
  let key = as_key!("test", "test", i);
  batch_reads.push(BatchRead::new(key, &bins));
}
match client.batch_get(&BatchPolicy::default(), batch_reads) {
    Ok(results) => {
      for result in results {
        match result.record {
          Some(record) => println!("{:?} => {:?}", result.key, record.bins),
          None => println!("No such record: {:?}", result.key),
        }
      }
    }
    Err(err) => println!("Error executing batch request: {}", err),
}

This call groups keys based on which Aerospike Server node can best handle the request, and uses the client’s thread pool to concurrently handle all requests to each node. After all nodes return the record data, the records are returned to the caller. The list of records returned is in the same order the keys are passed in. If a record is not found in the database, the batch read’s record entry is None.
