The queue allows the node to trace and finally provide these requests rather than discarding them. Thread pool rejections arise as soon as the thread pool’s greatest queue measurement (which varies based upon the type of thread pool) is reached.
relocating_shards: Shards that are in the entire process of shifting from 1 node to a different. Substantial quantities in this article could suggest ongoing rebalancing.
