############################# 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 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
|
||
log.retention.hours=24
|
||
|
||
# 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.
|
||
log.retention.bytes=104857600
|
||
|
||
# The maximum size of a log segment file. When this size is reached a new log segment will be created.
|
||
log.segment.bytes=104857600
|
||
|
||
# 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=60000
|
||
|
||
# By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires.
|
||
# If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction.
