Phoenix对接Superset+Presto

安装prestosql

参考：https://prestosql.io/docs/current/installation/deployment.html

Presto配置Phoenix连接

新建文件/presto-server-331/etc/catalog/phoenix.propertie
添加配置：

connector.name=phoenix
case-insensitive-name-matching=true
phoenix.connection-url=jdbc:phoenix:xxx,xxx,xxxx:2181:/hbase
phoenix.config.resources=/home/presto/hbase-site.xml,/home/presto/core-site.xml,/home/presto/hdfs-site.xml,/home/presto/ssl-client.xml`

问题：MySQL->PHONEIX->presto

• 由于PHONEIX中存储是GMT时区，会差8个小时，。也是查询phoniex的话还得加8小时，后来presto中不支持TimeStamp，直接改为bigint类型
• phoenix中的decimal类型在碰到类似1000的话会存储格式为科学记数法，比如1.32E+4
• 创建索引的时候，MySQL中的unique index 在phoenix中没有，只有CONSTRAINT pk PRIMARY KEY这种组合primary key
• MySQL中bit改为了tinyInt类型存储在Phoenix中
