Function cassandra_cpp_sys::cass_cluster_set_prepare_on_up_or_add_host

pub unsafe extern "C" fn cass_cluster_set_prepare_on_up_or_add_host(
    cluster: *mut CassCluster,
    enabled: cass_bool_t
) -> CassError

Enable pre-preparing cached prepared statements when existing hosts become available again or when new hosts are added to the cluster.

This can help mitigate request latency when executing prepared statements by avoiding an extra round trip in cases where the statement is unprepared on a freshly started server. The main tradeoff is extra background network traffic is required to prepare the statements on hosts as they become available.

Default: cass_true
