副本类型的说明详见官网文档

1、observer 需要 4.3.3.0 及其之上的版本。
2、ocp 需要 4.3.3 及其之上的版本当前还没有发布ocp 4.3.3。
3、obd 需要 2.10.1-1 及其之上的版本。
4、obproxy 需要 4.3.2 及其之上的版本。
5、不建议部署 2 个及以上数目的列存副本。
6、全功能和只读副本不支持转为列存副本列存副本也不支持转为全功能和只读副本。
7、物理恢复不支持恢复列存副本。
8、如果主库未部署列存副本备库也不建议部署列存副本。
9、列存表是指表的分区 Leader Follower 的 Schema 均为列存格式查询可以是强读
列存副本是在保证表的分区 Leader Follower 的 Schema 为行存格式的前提下只读副本 Learner 为列存格式并且 OLAP 的查询只能是弱读。 其他详见官网文档
