   100% solved, ran against production today.
   
   We decreased dispatcherMaxReadBatchSize=10000 to 500 for our Flink job because reading from all 8 partitions was OOM'ing the brokers with the memory allocation we had set.
   
   Running in production with graphs from Flink, this is 4x what we were getting before and we're seeing matching graphs in Pulsar's Grafana with 4x throughput.
