############################# Log Basics ############################# |

|
|
# The directory under which to store log files |
|
log.dir=/tmp/kafka-logs |

############################# Log Flush Policy ############################# |
|
|
|
# The following configurations control the flush of data to disk. This is the most |
|
# important performance knob in kafka. |
|
# There are a few important trade-offs here: |
|
# 1. Durability: Unflushed data is at greater risk of loss in the event of a crash. |
|
# 2. Latency: Data is not made available to consumers until it is flushed (which adds latency). |
|
# 3. Throughput: The flush is generally the most expensive operation. |
|
# 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 |
|
|
|
# Per-topic overrides for log.flush.interval.ms |
|
#log.flush.intervals.ms.per.topic=topic1:1000, topic2:3000 |

############################# Log Retention Policy ############################# |
|
|
|
# The following configurations control the disposal of log segments. The policy can |
|
# be set to delete segments after a period of time, or after a given size has accumulated. |
|
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens |
|
# from the end of the log. |
|
|
|
# The minimum age of a log file to be eligible for deletion |
|
log.retention.hours=168 |
|
|
|
# A size-based retention policy for logs. Segments are pruned from the log as long as the remaining |
|
# segments don't drop below log.retention.bytes. |
|
#log.retention.bytes=1073741824 |
|
|
|
# The maximum size of a log segment file. When this size is reached a new log segment will be created. |
|
log.segment.bytes=536870912 |

|
# to the retention policies |
