> In this Jira, we shall implement a cache for Table.
> As with OM HA, we are planning to implement double buffer implementation to flush transaction
in a batch, instead of using rocksdb put() for every operation. When this comes in to place
we need cache in OzoneManager HA to handle/server the requests for validation/returning responses.
>  
> This Jira will implement Cache as an integral part of the table. In this way users using
this table does not need to handle like check cache/db. For this, we can update get API in
the table to handle the cache.
>  
> This Jira will implement:
>  # Cache as a part of each Table.
>  # Uses this cache in get().
>  # Exposes api for cleanup, add entries to cache.
> Usage to add the entries in to cache will be done in further jira's.
