Hi, Let's say we have: 5 nodes 10 shards per index (with 1 replica) 10 vCPU per node (and 16 Go RAM with 8 Go heap) Will shard-scoped Painless script executions be multi-threaded on each node? E.g. will node 1 multi-thread execution of Painless script for shards 1 and 2? Or will node 1 execute …

All scripts (regardless of language) run in the thread of the calling context. So, for example, with a scoring script in a search, the script would be run on each shard independently, during query execution.
