Here are the optimizations I made to the cluster to increase indexing throughput:
Increased threadpool.bulk.queue_size to 500 because index requests were frequently overloading the queues Increased disk watermarks, because default settings were too aggressive for the large SSDs that we were using. I set "cluster.routing.allocation.disk.watermark.low": "100gb" and "cluster.routing.allocation.disk.watermark.high": "10gb" Deleted unused indexes to free up resources ES uses to manage their shards Increased number of primary shards to 175 with the goal of keeping shard size under 50GB and have approximately a shard per processor
