| The log management system for Kafka. |
| |
| The entry point for this system is LogManager. LogManager is responsible for holding all the logs, and handing them out by topic/partition. It also handles the enforcement of the |
| flush policy and retention policies. |
| |
| The Log itself is made up of log segments. A log is a FileMessageSet that contains the data and an OffsetIndex that supports reads by offset on the log. |
