description

该语句用于创建仓库。仓库用于属于备份或恢复。仅 root 或 superuser 用户可以创建仓库。
语法：
    CREATE [READ ONLY] REPOSITORY `repo_name`
    WITH [BROKER `broker_name`|S3]
    ON LOCATION `repo_location`
    PROPERTIES ("key"="value", ...);

说明：
    1. 仓库的创建，依赖于已存在的 broker 或者直接通过AWS s3 协议访问云存储
    2. 如果是只读仓库，则只能在仓库上进行恢复。如果不是，则可以进行备份和恢复操作。
    3. 根据 broker 或者S3的不同类型，PROPERTIES 有所不同，具体见示例。

example

1. 创建名为 bos_repo 的仓库，依赖 BOS broker "bos_broker"，数据根目录为：bos://palo_backup
    CREATE REPOSITORY `bos_repo`
    WITH BROKER `bos_broker`
    ON LOCATION "bos://palo_backup"
    PROPERTIES
    (
        "bos_endpoint" = "http://gz.bcebos.com",
        "bos_accesskey" = "bos_accesskey",
        "bos_secret_accesskey"="bos_secret_accesskey"
    );

2. 创建和示例 1 相同的仓库，但属性为只读：
    CREATE READ ONLY REPOSITORY `bos_repo`
    WITH BROKER `bos_broker`
    ON LOCATION "bos://palo_backup"
    PROPERTIES
    (
        "bos_endpoint" = "http://gz.bcebos.com",
        "bos_accesskey" = "bos_accesskey",
        "bos_secret_accesskey"="bos_accesskey"
    );

3. 创建名为 hdfs_repo 的仓库，依赖 Baidu hdfs broker "hdfs_broker"，数据根目录为：hdfs://hadoop-name-node:54310/path/to/repo/
    CREATE REPOSITORY `hdfs_repo`
    WITH BROKER `hdfs_broker`
    ON LOCATION "hdfs://hadoop-name-node:54310/path/to/repo/"
    PROPERTIES
    (
        "username" = "user",
        "password" = "password"
    );

4. 创建名为 s3_repo 的仓库，直接链接云存储，而不通过broker.
    CREATE REPOSITORY `s3_repo`
    WITH S3
    ON LOCATION "s3://s3-repo"
    PROPERTIES
    (
        "AWS_ENDPOINT" = "http://s3-REGION.amazonaws.com",
        "AWS_ACCESS_KEY" = "AWS_ACCESS_KEY",
        "AWS_SECRET_KEY"="AWS_SECRET_KEY",
        "AWS_REGION" = "REGION"
    );
