You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: local.rs
    path of file: ./repos/openobserve/src/service/db/file_list
    
    the code of the file until where you have to start completion: // Copyright 2023 Zinc Labs Inc.

pub async fn broadcast_cache(node_uuid: Option<String>) -> Result<(), anyhow::Error> {
    let files = infra_file_list::list()
        .await?
        .into_iter()
        .map(|(k, v)| FileKey::new(&k, v, false))
        .collect::<Vec<_>>();
    if files.is_empty() {
        return Ok(());
    }
    for chunk in files.chunks(100) {
        if let Err(e) = super::broadcast::send(chunk, node_uuid.clone()).await {
            log::error!("[FILE_LIST] broadcast cached file list failed: {}", e);
        }
    }
    Ok(())
