> Currently heap allocations for RS memory structures like {{memstore}} and
> {{lruCache}} are configured as percentage of total RS heap size. Since
> on-heap bucketCache uses RS heap, configuring it as a percentage of heap size
> will improve usability. Currently this can be configured either as a
> percentage of heap or a memory size in MiB and we can remove the latter
> option which is applicable to external or off-heap bucketCache.
