############################# 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 |
|
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. |
|
#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=536870912 |
|
|
|
# The interval at which log segments are checked to see if they can be deleted according |
|
# to the retention policies |

|
# You can also append an optional chroot string to the urls to specify the |
|
# root directory for all kafka znodes. |
