Log Service:Data encoding

Protobuf is used as a format to interchange structured data. Before you write logs to Log Service by calling relevant API operations, you must serialize raw log data to Protobuf data streams. The following sample is Protobuf-formatted data:

message Log
{
    required uint32 Time = 1;// UNIX Time Format
    message Content
    {
        required string Key = 1;
        required string Value = 2;
    }  
    repeated Content Contents = 2;
}

message LogTag
{
    required string Key = 1;
    required string Value = 2;
}

message LogGroup
{
    repeated Log Logs= 1;
    optional string Reserved = 2; // reserved fields
    optional string Topic = 3;
    optional string Source = 4;
    repeated LogTag LogTags = 6;
}

message LogGroupList
{
    repeated LogGroup logGroupList = 1;
}
