> 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.
