You can log in to the CLS console and ship data in JSON format to COS. This document describes how to create a JSON shipping task.
The parameters are described as follows:
|Shipping Task Name||Configures the name of a shipping task||The name can contain letters, numbers, underscores (_), and hyphens (-)||Yes|
|COS Bucket||Target bucket for shipping. The target bucket must be in the same region as the current log topic.||A value selected from the drop-down list||Yes|
|COS Path||COS bucket path, which is in the format of `/year/month/day/hour/` by default, such as `/2022/7/31/14/`. This format is used in COS for storing shipped log files. Here, the strftime syntax is supported. For example, if a log was shipped at 14:00 on July 31, 2022, the generated `/%Y/%m/%d/` path is `/2022/7/31/`, and the `/%Y%M%d/%H/` path is `/2022/07/31/14/`.||Cannot start with
|Filename||Option 1 (recommended): Use the shipping time as the name. For example, `202208251645_000_132612782.gz` indicates the shipping time_log topic partition_offset. This type of files can be loaded in Hive.
Option 2: Use a random number as the name. This is the legacy practice of naming files and cannot be recognized by Hive as it cannot recognize filenames starting with "_". You can add a custom prefix to the COS path, such as `/%Y%M%d/%H/Yourname`.
|Compression Format||To reduce read traffic fees, log files are compressed before being shipped to COS. Snappy, lzop, and GZIP are supported.||GZIP, Snappy, and lzop||Yes|
|File Size||It indicates the size of the raw log file to be shipped and is used together with the shipping interval parameter. When either condition is met, compression will be performed accordingly. For example, if the size is set to 256 MB and the interval is set to 15 minutes, when the file reaches 256 MB within five minutes, the size condition will be met first to trigger shipping.||The value must be a number ranging from 5 to 256 in MB.||Yes|
|Shipping Interval||It indicates the interval for shipping and is used together with the file size parameter. When either condition is met, compression will be performed accordingly. For example, if the size is set to 256 MB and the interval is set to 15 minutes, when the file reaches only 200 MB in 15 minutes, the shipping interval condition will be met first to trigger shipping.||Value range: 300-900s||Yes|
