分布的方式,将业务数据表的元组按合适的分布策略分散存储在所有的DN。 当前产品支持复制(Replication)、散列(Hash)和轮询(Roundrobin)三种用户表分布策略。 Replication方式:在每一个DN上存储一份全量表数据。对于数据量比较小的表建议采取Replication分布策略。
错误原因:读取COPY文件出现失败。 解决办法:请检查文件数据格式合法性,具体请参考《SQL语法参考》的“COPY”章节。 GAUSS-01248: "invalid field size" SQLSTATE: 22P04 错误原因:读取COPY文件中数据大小错误。 解决办法:请检查文件数据格式
