Operation description

Usage notes

Host consists of a project name and a Simple Log Service endpoint. You must specify a project in Host.
Each shard has an MD5 hash range, and each range is a left-closed, right-open interval. The interval is in the [BeginKey,EndKey) format. A shard can be in the readwrite or readonly state. You can split a shard and merge shards. For more information, see Shard .

Debugging
