A log group is a group of logs that serves as the basic unit for read/write operations. Logs in a log group have the same metadata such as the IP address and source.

When data is written through the Log Service API or SDK, multiple log entries are packaged into a log group and sent to Log Service. Compared with reading and writing data by log, reading and writing data by log group can minimize the number of read/write operations and improve business efficiency.

A log group has a maximum size of 5 MB.
