# # This configuration file is intended for use in KRaft mode, where # Apache ZooKeeper is not present. #
############################# Server Basics #############################
# The role of this server. Setting this puts us in KRaft mode process.roles=broker,controller
# The node id associated with this instance's roles node.id=1
# The connect string for the controller quorum controller.quorum.voters=1@10.9.98.111:9093,2@10.9.98.214:9093
############################# Socket Server Settings #############################
# The address the socket server listens on. # Combined nodes (i.e. those with `process.roles=broker,controller`) must list the controller listener here at a minimum. # If the broker listener is not defined, the default listener will use a host name that is equal to the value of java.net.InetAddress.getCanonicalHostName(), # with PLAINTEXT listener name, and port 9092. # FORMAT: # listeners = listener_name://host_name:port # EXAMPLE: # listeners = PLAINTEXT://your.host.name:9092 listeners=PLAINTEXT://:9092,CONTROLLER://:9093
# Name of listener used for communication between brokers. inter.broker.listener.name=PLAINTEXT
# Listener name, hostname and port the broker or the controller will advertise to clients. # If not set, it uses the value for "listeners". advertised.listeners=PLAINTEXT://10.9.98.111:9092,CONTROLLER://10.9.98.111:9093
# A comma-separated list of the names of the listeners used by the controller. # If no explicit mapping set in `listener.security.protocol.map`, default will be using PLAINTEXT protocol # This is required if running in KRaft mode. controller.listener.names=CONTROLLER
# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details listener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL
# The number of threads that the server uses for receiving requests from the network and sending responses to the network num.network.threads=3
# The number of threads that the server uses for processing requests, which may include disk I/O num.io.threads=8
# The send buffer (SO_SNDBUF) used by the socket server socket.send.buffer.bytes=102400
# The receive buffer (SO_RCVBUF) used by the socket server socket.receive.buffer.bytes=102400
# The maximum size of a request that the socket server will accept (protection against OOM) socket.request.max.bytes=104857600
# A comma separated list of directories under which to store log files log.dirs=/tmp/kraft-combined-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. num.recovery.threads.per.data.dir=1
############################# 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 to ensure availability such as 3. offsets.topic.replication.factor=1 transaction.state.log.replication.factor=1 transaction.state.log.min.isr=1
# 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 excessive 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
# 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 unless the remaining # segments 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
