> 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.
