> Implement Redis cache for pipelines' states
> -------------------------------------------
>
> Key: BEAM-13023
> URL: https://issues.apache.org/jira/browse/BEAM-13023
> Project: Beam
> Issue Type: Sub-task
> Components: beam-playground
> Reporter: Artur Khanin
> Assignee: Aydar Zaynutdinov
> Priority: P3
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> The backend should be able to use Redis to:
> * save cache value by *pipelineId* and one more *sub-key* as a nested
> structure
> * get cache by *pipelineId* and one more *sub-key*
> * set time expiration for *pipelineId* key
>
> Inner Redis client should be an implementation of *Cache* interface, so that
> it could be used like *LocalCache*.
