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