########################### 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@10.8.3.35:9093,2@10.8.3.36:9093,3@10.8.3.37:9093

########################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://10.8.3.35:9092,CONTROLLER://10.8.3.35:9093

# Name of listener used for communication between brokers.

inter.broker.listener.name=PLAINTEXT

# Listener name, hostname and port the broker will advertise to clients.

# If not set, it uses the value for "listeners".

advertised.listeners=PLAINTEXT://10.8.3.35:9092

# 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

############################# Log Basics ###########################

# A comma separated list of directories under which to store log files

log.dirs=/usr/local/kafka/logs/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

########################### 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 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
