Apache Paimon是一种湖格式,可以使用Flink和Spark构建实时湖屋架构,用于流式和批处理操作。Paimon创新性地将lake格式和LSM(日志结构合并树)结构相结合,将实时流式更新引入lake架构。
Paimon提供以下核心功能:
*实时更新:
*主键表支持写入大规模更新,具有很高的更新性能,通常通过Flink Streaming。
*支持定义合并引擎,以您喜欢的方式更新记录。重复数据删除以保留最后一行、部分更新、聚合记录或第一行,由您决定。
*支持定义变更日志生成器,为合并引擎生成正确完整的变更日志更新,简化您的流式分析。
*海量附加数据处理:
*附加表(无主键)提供大规模批处理和流处理能力。自动小文件合并。
*支持数据压缩和z顺序排序,以优化文件布局,使用minmax等索引提供基于数据跳过的快速查询。
*数据湖功能:
*可扩展元数据:支持存储Petabyte大规模数据集和存储大量分区。
*支持ACID事务、时间旅行和模式演化。
the environment includes:
- minio
- pamion
- flink
Centos 更换 tencent 的yum源
备份系统旧配置文件
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
获取对应版本的CentOS-Base.repo 到/etc/yum.repos.d/目录
各版本源配置列表
CentOS7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
CentOS8
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos8_base.repo

创建 Iceberg Catalog 和表
```sql
-- if you're trying out Paimon in a distributed environment,
-- the warehouse path should be set to a shared file system, S3 minio
CREATE CATALOG my_catalog WITH (
'type' = 'paimon',
'warehouse' = 's3://warehouse/wh',
's3.endpoint'='http://192.168.116.130:9000',
's3.access-key' = 'admin',
's3.secret-key' = 'password',
's3.region' = 'us-east-1'
);
USE CATALOG my_catalog;
-- create a word count table
CREATE TABLE word_count (
word STRING PRIMARY KEY NOT ENFORCED,
cnt BIGINT
);
创建完表,可以登录 minio:9001地址进行查看数据文件;
插入数据
USE CATALOG my_catalog;
-- insert data into word count table
insert into word_count values ('hello',2);
后面, 根据你的业务创建 flink job任务,进行数据写入;
