The following configurations control the flush of data to disk. + # 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 exceessive 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).
