I see always relocation going on, should I be worried?

Elastic Stack Elasticsearch

We see relocation always goes in max as mentioned for cluster_concurrent_rebalance, and drops down to some lesser number and again climbs back to max.

1). Should I be worried?
2). Is there a queue that says how many more pending shards to relocate? Whats the curl to fetch the queue?
3). Does it take max priority in cpu and memory? when write or read comes to the relocating node, does app response go low any latency expected?

Which version of Elasticsearch are you using?

Are you using the default settings or have you made any changes?

ES: 8.9, settings are default . cluster_concurrent_rebalance : 2.
