sessionVariables=tidb_isolation_read_engines=tiflash 报 Can not find access path matching 'tidb_isolation_read_engines'(value: 'tiflash'). Available values are 'tikv'
还有
set @@session.tidb_isolation_read_engines = "tiflash,tidb";
最终使用实例级别的隔离
[isolation-read]
engines = [“tidb”, “tiflash”]
Can not find access path matching ‘tidb_isolation_read_engines’(value: ‘tiflash’). Available values are ‘tikv’
报这个错,应该是预发环境,TIKV强制下线数据有问题导致的
