导出数据
TDSQL MySQL 版支持通过 mysqldump 导出数据，导出前须设置 net_write_timeout 参数：
set global net_write_timeout=28800，命令行有权限限制，请通过 TDSQL MySQL 版控制台 操作。mysqldump --compact --single-transaction --no-create-info -c db_name table_name -utest -h10.xx.xx.34 -P3336 -ptest123
说明：
db 和 table 名参数根据实际情况选择，如果导出的数据要导入到另外一套 TDSQL MySQL 版环境的话，必须加上 -c 选项。
导出帐号需拥有
select on *.* 的权限。导入数据
TDSQL MySQL 版提供专门的导入数据工具，完成 load data outfile 对应数据的导入，该工具的原理是把源文件按照 shardkey 的路由规则，切分成多个文件，然后把每个单独透传到对应的后端数据库。
[tdengine@TENCENT64 ~/]$./load_dataformat:./load_data mode0/mode1 proxy_host proxy_port user password db_table shardkey_index file field_terminate filed_enclosedexample:./load_data mode1 10.xx.xx.10 3336 test test123 shard.table 1 '/tmp/datafile' ' ' ''
注意：
源文件必须以 '\\n' 作为换行符。
mode0 只切分源文件，不做数据导入，一般用于调试，正式导入数据使用 mode1。
shardkey_index 从0开始，如果 shardkey 在第2个字段，则 shardkey_index 为1。
