2G.分表分库话题

有关数据库和数据操作的话题

2G.01. No implementation SPI

No implementation class load from SPI with type null

命名中避免使用中文，边界测试时，发现shardingsphere可以直接中文表名，但对其他命名会截断错误。 如sharding-algorithms.[中文也分表-inline]，会截断错误，使其.type=null，从而报错， No implementation class load from SPI org.apache.shardingsphere.sharding.spi.ShardingAlgorithm with type null

2G.02.ON DUPLICATE KEY UPDATE

INSERT INTO ... ON DUPLICATE KEY UPDATE can not support update for sharding column

then append sharding column and value to WHERE Clause

此功能大概在 5.1.0发布
