Log Service provides the real-time log consumption feature. This feature reads and writes full data in the first-in, first-out (FIFO) order, which is similar to Kafka. This topic describes the types of real-time log consumption.

After log data is sent to Log Service, you can process the data in the following three methods.
Method Scenario Timeliness Retention period
Real-time log consumption Stream computing and real-time computing Real time You can set a retention period based on your business requirements.
Log query Online query of recent hot data Near real time (delayed for 1 second in 99.9% cases, and up to 3 seconds) You can set a retention period based on your business requirements.
Log shipping Full log storage for offline analysis Delayed for 5 to 30 minutes The retention period is subject to the storage system.
