| 30 | |
| 31 | # Hostname the broker will advertise to producers and consumers. If not set, it uses the |

| 66 | ############################# Log Flush Policy ############################# |
| 67 | |
| 68 | # Messages are immediately written to the filesystem but by default we only fsync() to sync |
| 69 | # the OS cache lazily. The following configurations control the flush of data to disk. |
| 70 | # There are a few important trade-offs here: |
| 71 | # 1. Durability: Unflushed data may be lost if you are not using replication. |
| 72 | # 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. |
| 73 | # 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks. |
| 74 | # The settings below allow one to configure the flush policy to flush data after a period of time or |
| 75 | # every N messages (or both). This can be done globally and overridden on a per-topic basis. |
| 76 | |
| 77 | # The number of messages to accept before forcing a flush of data to disk |
| 78 | log.flush.interval.messages=10000 |
| 79 | |
| 80 | # The maximum amount of time a message can sit in a log before we force a flush |
| 81 | log.flush.interval.ms=1000 |
| 82 | |
| 83 | ############################# Log Retention Policy ############################# |
| 84 | |
| 85 | # The following configurations control the disposal of log segments. The policy can |
| 86 | # be set to delete segments after a period of time, or after a given size has accumulated. |
| 87 | # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens |
| 88 | # from the end of the log. |
| 89 | |
| 90 | # The minimum age of a log file to be eligible for deletion |
| 91 | log.retention.hours=24 |
| 92 | |
| 93 | # A size-based retention policy for logs. Segments are pruned from the log as long as the remaining |
| 94 | # segments don't drop below log.retention.bytes. |
| 95 | log.retention.bytes=104857600 |
| 96 | |
| 97 | # The maximum size of a log segment file. When this size is reached a new log segment will be created. |
| 98 | log.segment.bytes=104857600 |
| 99 | |
| 100 | # The interval at which log segments are checked to see if they can be deleted according |
| 101 | # to the retention policies |
| 102 | log.retention.check.interval.ms=60000 |
| 103 | |
| 104 | # By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires. |
| 105 | # If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction. |
| 106 | log.cleaner.enable=false |

| 108 | ############################# Zookeeper ############################# |
| 109 | |
| 110 | # Zookeeper connection string (see zookeeper docs for details). |
| 111 | # This is a comma separated host:port pairs, each corresponding to a zk |
| 112 | # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002". |
| 113 | # You can also append an optional chroot string to the urls to specify the |
| 114 | # root directory for all kafka znodes. |
