lakefs 集成presto/trinodb
presto 集成lakefs 主要利用了hive connector
预备
需要hive metadata

- hive metadata 配置
结合实际修改
<configuration>
<property>
<name>hive.metastore.uris</name>
<value>thrift://hive:9083</value>
<description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description>
</property>
<property>

<value>ayPIL/XuHlPCNUp1x+0dQfyvXCZFp8g+BewEy7bX</value>
</property>
</configuration>
- trinodb 配置
lakefs.properties
connector.name=hive-hadoop2
hive.metastore.uri=thrift://hive-metastore:9083
hive.non-managed-table-writes-enabled=true
hive.s3select-pushdown.enabled=true
hive.s3.aws-access-key=AKIAJXJ3AX5EWAAYO3GQ
hive.s3.aws-secret-key=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
hive.s3.endpoint=http://lakefs:8000
hive.s3.path-style-access=true
hive.s3.ssl.enabled=false
hive.allow-drop-table=true
hive.allow-add-column=true
hive.allow-drop-column=true
hive.allow-rename-table=true
hive.allow-rename-column=true
- 初始化lakefs
启动之后http://localhost:8000/setup
链接trinodb
可以使用dbeaver 
- 创建lakefs schema 以及table
CREATE SCHEMA lakefs.main
WITH (location = 's3a://dalong/main')
CREATE TABLE lakefs.main.page_views2 (
user_id bigint,
page_url varchar,
country varchar
)
WITH (
format = 'ORC',
bucketed_by = ARRAY['user_id'],
bucket_count = 50
)
insert into lakefs.main.page_views2(user_id,page_url,country) values (333,'https://www.baidu.com','dalong')
- 效果
数据 
lakefs 
说明
以上是一个简单的集成，table格式使用了orc，实际上我们也可以使用parquet 这样就可以集成dremio了，实际上dremio 集成其他格式的方法挺多，但是目前
因为dremio并不是完全开源（特性以及完全有商业左右）并不是特别的好，我们可以基于如下扩展
基于hive metadata 服务扩展存储，然后基于自定义的存储插件解决（性能可能不会太好），还有就是基于jdbc 驱动
