200 primary shards 200 unassigned

Hello

I'm new to ES. I'm trying to understand what does this mean .
When I curl the cluster health status I'm seing 200 primary shards and 200 unassigned shards.
Does this have an impact on my cluster?

If this is a new, single node cluster, you probably have a default of 1 replica. With only one node, of course primary shards have to be on that node. Replica shards must be on a different node, so they can't (yet) be allocated. If you added a second node, replicas would be created. You can also set replica = 0 on your shards and clear the "error".
