      # There are a few important trade-offs here:
      #    1. Durability: Unflushed data may be lost if you are not using replication.
      #    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
      #    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
      # The settings below allow one to configure the flush policy to flush data after a period of time or
      # every N messages (or both). This can be done globally and overridden on a per-topic basis.

      # The number of messages to accept before forcing a flush of data to disk
