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). 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 +#log.flush.interval.messages=10000 + +# The maximum amount of time a message can sit in a log before we force a flush +#log.flush.interval.ms=1000 + +############################# Log Retention Policy ############################# + +# The following configurations control the disposal of log segments.
