在代理中设置kafka消息的最大生存期的位置？

Question

在lifetime中设置kafka条消息的最大broker的位置？什么是默认值？

如果我使用Kafka组合的Spark流媒体，这个设置有什么不同吗？

Answer 1

您可以使用以下命令在代理的 server.properties 文件中设置kafka主题的保留期（生命周期）：

# The below 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
