Hi @masseyke, I've created a changelog YAML for you. |
…yke/elasticsearch into throttle-reindex-requests-per-node
|
I'm closing this one because the benefit we get is probably not worth the added complexity. We might revisit this if we start seeing real-world problems. |

NOTE: This is currently a draft, created so that we can discuss whether the added complexity is worth the benefit we get from it. It is not ready for review.
We allow users to configure the number of indices we reindex in parallel from the reindex data stream API. It is possible that a user could set this to a very high value, and then swamp the cluster with reindex requests. This change makes it so that we send no more than 10 reindex requests to any node at a time. It builds on the work done in #125171.
