【feature】mystreamer支持upstream和downstream使用不同的存储引擎
blackghost-01 opened this issue · comments
数据迁移过程中（例如历史数据归档），源库和目标库希望使用不同的存储引擎（比如tokudb或者myrocks），达到数据压缩等目的。所以就需要在导入时，支持指定存储引擎类型，或者导出时忽略存储引擎选项（目标库有设置选定的默认存储引擎）
Hi @blackghost-01 ,
From the mystreamer side, we should to parse the table schema and change the ENGINE option to TokuDB/MyRocks or others, so we think this issue priority is lower.
As you said, we can do that by setting the default engine.
Thanks.
期待实现

Now, we can use the flage '--2engine=tokudb' to replace the upstream engine.
-2engine string
Downstream table engine
great job
