It would mean that you are going to accumulate up to 1000 requests of 2500 docs at a time in memory. That could be a lot. You need to monitor that. That’s a lot of objects that might be GCed at some point.
If your bulk request is rejected, why not trying to slow down injection rate instead of filling the memory? You could also think of setting replicas to 0 before bulk and the reactivate to 1 after injection. Having SSD drives can also help but may be you have already that?
