! # Download mongodb FTDC data
!
! Crate to enable your application to download FTDC data from mongodb clusters to investigate deeper (e.g. keyhole (https://github.com/simagix/keyhole)).
!
! ## Usage
!
! To download FTDC data from a mongodb cluster you need to provide some input to the CLI:
!
! 1. Group key: The group key (or: project id) the respective cluster belongs too. It is encoded into the link you get from atlas when selecting the specific cluster on Atlas UI (e.g.cloud.mongodb.com/v2/{group key}clusters)
! 2. Replicaset name: The name of the replica set the data should be loaded from. You can either provide the direct targeted replica set name (e.g. atlas-<something>-shard-0) or the name of the shard (e.g some-name-shard-00). Do not forget the number here as it qualifies the shard in case you want data from a sharded cluster. For a standalone replica set it is00 but lets say for a sharded cluster with 3 shards it would be 00, 01, 02.
! 3. API key: You need to have a valid API key for at least the cluster you want to download FTDC data from.

! ## Example
!
! ! use error::Error; ! use reqwest::Client; ! use service::{FtdcDataService, FtdcLoader}; ! ! #[tokio::main] ! async fn main() -> Result<(), Error> { ! let group_key = "..."; ! let replica_set_name = "..."; ! let size = 10_000_000 ! let public = "..."; ! let private = "..."; ! ! let service = FtdcDataService { client: Client::new() }; ! ! service ! .get_ftdc_data( ! group_key, ! replica_set_name, ! size, ! public, ! private, ! ) ! .await ! .map(|download_path| println!("Downloaded to: `{}`", download_path)) ! } !
!
! The data is downloaded to the current directory the application was executed in as a *.tar.gz.
