pub async fn is_first_launch_for_sql_backend_cluster(
sql_meta_store: &SqlMetaStore,
) -> MetaResult<bool>Expand description
This function is_first_launch_for_sql_backend_cluster is used to check whether the cluster, which uses SQL as the backend, is a new cluster.
It determines this by inspecting the applied migrations. If the migration m20230908_072257_init has been applied,
then it is considered an old cluster.
Note: this check should be performed before Migrator::up().
