> Now when Master run a workflow, it will do many db select operation, such
as processDefinition, taskDefinition, processTaskRelation, tenant, user,
workGroup, project......
If the cache is only for DB operations, maybe we can investigate whether the
ORM framework supports cache itself, I remember MyBatis supports some basic
cache mechanism.
> function design:
>
> * [ ] add the cache switch, it can be controlled by user freely. If
false, the cache will not effect
> * [ ] cache expire config, it will decide how long the cache will last
> * [ ] cache annotation, which can be use easily, and it's helpful to
manage the unified cache logic
> * [ ] cache hit rate statistics
> * [ ] cache update notify, now is from api-server
All the functionalities above can be easily achieved by introducing
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-cache</artifactId>
</dependency>
```
@caishunfeng which cache system do we want to use?
