About restarting VM instance group

Hi,

As I know, when I run the Beam Enrich or BigQuery loader VM instance, it will launch an additional dataflow job in another VM instance. I am wondering whether the dataflow job will also restart if I restart the Beam Enrich or BigQuery loader VM instance group. What is the best practice if I changed some enrichment or bigquery configuration, or iglu schema files in Google Cloud Storage? Thanks!
