You probably have some naughty partitions with heavy write throughput, you
can check by following Prometheus query:
```
pulsar_throughput_in{cluster="YOUR_CLUSTER_NAME"} > 5 * 1024^2
```
If you discover partitions with excessive write loads, consider increasing
the number of partitions for the affected topics. This will help distribute the
write throughput more evenly across your bookie instances.
Notes about Pulsar message publishing:
- Each partition maintains exactly one writable ledger at a time
- With configuration `ensembleSize=2, writeQuorum=2`:
- A partition with `100MB/s` write throughput will generate approximately
`100MB/s` write load on each bookie in the ensemble
- Bookies not in the current ensemble will not receive any writes from
this ledger
