> If rocksdb.cache.size.bytes is set, then it's not equally divided among all the containers, we can get rid of this configuration
>     cacheSizePerContainer = storeConfig.getLong("rocksdb.cache.size.bytes", cacheSizePerContainer)
> We already have an configuration: 
>     val cacheSize = storeConfig.getLong("container.cache.size.bytes", 100 * 1024 * 1024L)
> which sets the block cache and is set divided amongst all tasks, which should be sufficient.
