############################# Socket Server Settings ############################# |
|
|
|
# The address the socket server listens on. It will get the value returned from |
|
# java.net.InetAddress.getCanonicalHostName() if not configured. |
|
# FORMAT: |
|
# listeners = listener_name://host_name:port |
|
# EXAMPLE: |
|
# listeners = PLAINTEXT://your.host.name:9092 |
|
#listeners=PLAINTEXT://:9092 |
|
|
|
# Hostname and port the broker will advertise to producers and consumers. If not set, |
|
# it uses the value for "listeners" if configured. Otherwise, it will use the value |
|
# returned from java.net.InetAddress.getCanonicalHostName(). |
|
#advertised.listeners=PLAINTEXT://your.host.name:9092 |

|
# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details |

############################# Log Basics ############################# |
|
|
|
# A comma seperated list of directories under which to store log files |
|
log.dirs=/tmp/kafka-logs |
|
|
|
# The default number of log partitions per topic. More partitions allow greater |
|
# parallelism for consumption, but this will also result in more files across |
|
# the brokers. |
|
num.partitions=1 |
|
|
|
# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown. |
|
# This value is recommended to be increased for installations with data dirs located in RAID array. |

############################# Internal Topic Settings ############################# |
|
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state" |
|
# For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3. |

############################# Log Flush Policy ############################# |
|
|
|
# Messages are immediately written to the filesystem but by default we only fsync() to sync |
|
# the OS cache lazily. 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. 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 due to age |
|
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. Functions independently of log.retention.hours. |
|
#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=1073741824 |
|
|
|
# The interval at which log segments are checked to see if they can be deleted according |
|
# to the retention policies |
|
log.retention.check.interval.ms=300000 |
|

############################# Zookeeper ############################# |

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