DataX的python3使用

datax这东西本身是python2写的，这导致python3，就各种语法报错，问题是，现在的工程都是python3搞的，这就很难受....

网上找到一篇帖子，可以解决这个问题：

原帖：python3执行datax报错问题解决办法 - 卷心菜的奇妙历险 - 博客园

怕回头原帖看不了了，再记录一次，这，很无奈.....之前一些帖子，突然就看不了了....

解决办法

路径 datax/bin/  下

    where:           limit the scope of the performance data set
    fetchSize:       how many rows to be fetched at each communicate
    [these params is for stream reader, used to trace rdbms write performance]
    reader-sliceRecordCount:  how man test data to mock(each channel), the default value is 10000
    reader-column          :  stream reader while generate test data(type supports: string|long|date|double|bool|bytes; support constant value and random function)，demo: [{"type":"string","value":"abc"},{"type":"string","random":"10,20"}]
The following params are available for -w --writer:
    [these params is for rdbms writer, used to trace rdbms write performance, it's like datax's key]
    datasourceType:  datasource type, may be mysql|drds|oracle|ads|sqlserver|postgresql|db2|ads etc...
    *jdbcUrl:        datasource jdbc connection string, mysql as a example: jdbc:mysql://ip:port/database
    *username:       username for datasource
    *password:       password for datasource
    *table:          table name for write data
    column:          column to be writed, the default value is ['*']
    batchSize:       how many rows to be storeed at each communicate, the default value is 512
    preSql:          prepare sql to be executed before write data, the default value is ''
    postSql:         post sql to be executed end of write data, the default value is ''
    url:             required for ads, pattern is ip:port
    schme:           required for ads, ads database name
    [these params is for stream writer, used to trace rdbms read performance]
    writer-print:           true means print data read from source datasource, the default value is false
The following params are available global control:
    -c --channel:    the number of concurrent tasks, the default value is 1
    -f --file:       existing completely dataX configuration file path
    -t --type:       test read or write performance for a datasource, couble be reader or writer, in collaboration with -f --file
    -h --help:       print help message
some demo:
perftrace.py --channel=10 --reader='{"jdbcUrl":"jdbc:mysql://127.0.0.1:3306/database", "username":"", "password":"", "table": "", "where":"", "splitPk":"", "writer-print":"false"}'
perftrace.py --channel=10 --writer='{"jdbcUrl":"jdbc:mysql://127.0.0.1:3306/database", "username":"", "password":"", "table": "", "reader-sliceRecordCount": "10000", "reader-column": [{"type":"string","value":"abc"},{"type":"string","random":"10,20"}]}'
perftrace.py --file=/tmp/datax.job.json --type=reader --reader='{"writer-print": "false"}'
perftrace.py --file=/tmp/datax.job.json --type=writer --writer='{"reader-sliceRecordCount": "10000", "reader-column": [{"type":"string","value":"abc"},{"type":"string","random":"10,20"}]}'
some example jdbc url pattern, may help:
jdbc:oracle:thin:@ip:port:database
jdbc:mysql://ip:port/database
jdbc:sqlserver://ip:port;DatabaseName=database
jdbc:postgresql://ip:port/database
warn: ads url pattern is ip:port
warn: test write performance will write data into your table, you can use a temporary table just for test.
