Phoenix定位为OLTP和操作型分析(operational analytics)，大多用于在线业务，稳定性要求第一位。Phoenix的功能很强大，也很灵活，Phoenix SQL基于SQL-92标准，但是还是有很多方言，使用时需要特别注意。
DataX是阿里巴巴集团内被广泛使用的离线数据同步工具/平台，实现包括 MySQL、Oracle、SqlServer、Postgre、HDFS、Hive、ADS、HBase、TableStore(OTS)、MaxCompute(ODPS)、DRDS 等各种异构数据源之间高效的数据同步功能。
这里主要用到oraclereader和hbase11xwriter。

使用oraclereader和hbase11xwriter。
具体配置zlxx_test.json

数据库连接和用户名密码等配置在服务器的环境变量中

# Phoenix使用as select创建视图映射到HBase表
先创建Phoenix schema：
0: jdbc:phoenix:> create schema ZLXX;No rows affected (0.012 seconds)创建视图，由于Phoenix大小写最终都是大写，所以这里可以使用小写
create view ZLXX.WT_TRADE_REFUND ( id varchar primary key, info.trade_id varchar, info.amount varchar, info.status varchar, info.modify_time varchar) as select * from zlxx.wt_trade_refund;视图创建效果：
0: jdbc:phoenix:> create view ZLXX.WT_TRADE_REFUND (. . . . . . . . > id varchar primary key,. . . . . . . . > info.trade_id varchar,. . . . . . . . > info.amount varchar,. . . . . . . . > info.status varchar,. . . . . . . . > info.modify_time varchar. . . . . . . . > ) as select * from zlxx.wt_trade_refund;No rows affected (5.956 seconds)# 走一个查询试试看(完美)
0: jdbc:phoenix:> select * from zlxx.wt_trade_refund limit 5;+----------+------------+---------+---------+-----------------+| ID | TRADE_ID | AMOUNT | STATUS | MODIFY_TIME |+----------+------------+---------+---------+-----------------+| 1005528 | T12059592 | 100 | 01 | 20200228185803 || 1005529 | T12059591 | 10 | 03 | 20200228185846 || 1005530 | T12059606 | 10 | 01 | 20200228195442 || 1005531 | T12059605 | 10 | 01 | 20200228195442 || 1005532 | noTradeId | 100 | 03 | 20200229224015 |+----------+------------+---------+---------+-----------------+5 rows selected (0.062 seconds)# Phoenix使用column_encoded_bytes=0
创建视图映射到HBase表(测试下多视图)
由于需要名字相同，先把上面的view ZLXX.WT_TRADE_REFUND删除，稍后再使用as select创建不同名称的视图。
删除视图：
drop view ZLXX.WT_TRADE_REFUND;创建视图：
create view ZLXX.WT_TRADE_REFUND ( id varchar primary key, info.trade_id varchar, info.amount varchar, info.status varchar, info.modify_time varchar) column_encoded_bytes=0;也是正常的，能够看到有数据查询出来
0: jdbc:phoenix:> drop view ZLXX.WT_TRADE_REFUND;No rows affected (0.046 seconds)0: jdbc:phoenix:> create view ZLXX.WT_TRADE_REFUND (. . . . . . . . > id varchar primary key,. . . . . . . . > info.trade_id varchar,. . . . . . . . > info.amount varchar,. . . . . . . . > info.status varchar,. . . . . . . . > info.modify_time varchar. . . . . . . . > ) column_encoded_bytes=0;No rows affected (0.041 seconds)limit查询数据：
0: jdbc:phoenix:> select * from zlxx.wt_trade_refund limit 5;+----------+------------+---------+---------+-----------------+| ID | TRADE_ID | AMOUNT | STATUS | MODIFY_TIME |+----------+------------+---------+---------+-----------------+| 1005528 | T12059592 | 100 | 01 | 20200228185803 || 1005529 | T12059591 | 10 | 03 | 20200228185846 || 1005530 | T12059606 | 10 | 01 | 20200228195442 || 1005531 | T12059605 | 10 | 01 | 20200228195442 || 1005532 | noTradeId | 100 | 03 | 20200229224015 |+----------+------------+---------+---------+-----------------+5 rows selected (0.056 seconds)下面使用as select创建名称不同的视图，假设不需要status字段
create view ZLXX.WT_TRADE_REFUND2 ( id varchar primary key, info.trade_id varchar, info.amount varchar, info.modify_time varchar) as select INFO.TRADE_ID, INFO.AMOUNT, INFO.MODIFY_TIME from zlxx.wt_trade_refund;会报错
0: jdbc:phoenix:> create view ZLXX.WT_TRADE_REFUND2 (. . . . . . . . > id varchar primary key,. . . . . . . . > info.trade_id varchar,. . . . . . . . > info.amount varchar,. . . . . . . . > info.modify_time varchar. . . . . . . . > ) as select INFO.TRADE_ID, INFO.AMOUNT, INFO.MODIFY_TIME from zlxx.wt_trade_refund;Error: ERROR 604 (42P00): Syntax error. Mismatched input. Expecting "ASTERISK", got "INFO" at line 6, column 13. (state=42P00,code=604)org.apache.phoenix.exception.PhoenixParserException: ERROR 604 (42P00): Syntax error. Mismatched input. Expecting "ASTERISK", got "INFO" at line 6, column 13.同一张表创建名称不同的视图：
create view ZLXX.WT_TRADE_REFUND2 ( id varchar primary key, info.trade_id varchar, info.amount varchar, info.status varchar, info.modify_time varchar) as select * from zlxx.wt_trade_refund; 则是可以的

Phoenix端查询数据
总结：
1.hbase shell这边创建表时，命名空间namespace和表名称都要大写，这样方便Phoenix这边小写。
2.在hbase shell这边，命名空间与表名称之间需要注意是双引号，DataX里的全表名称也是如此。
3.Phoenix这边创建相同命名空间名称的schema。
4.Phoenix这边创建view视图映射有两种方式：as select和column_encoded_bytes=0。
