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

# listeners = PLAINTEXT://your.host.name:9092

|
num.partitions=1
|
|
|
|
# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.

############################# Internal Topic Settings #############################
|
|
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state"

############################# 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.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 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
