> In upgrading Rocks from v5.15 to v5.18, several of the RocksDB#compactRange() methods were deprecated in favor of variations leveraging the new CompactRangeOptions object. However v5.18 left a gap in the API with no signature allowing you to pass in an options object without also passing it a start, end byte[] specifying a range to be compacted. Since we would like to compact the entire thing and not a subrange, while needing to specify several options, the deprecation warning was suppressed for now.
> In v6.0 this gap is closed as you can pass null in for start, end to specify that the entire range should be compacted.
> When upgrading Rocks to v6.0 or later, the deprecation suppressions should be removed from DualColumnFamilyAccessor#toggleDBForBulkLoading() (RocksDBTimestampedStore.java) and and SingleColumnFamilyAccessor#toggleDBForBulkLoading() (RocksDBStore.java) and the following replacement should be made:
>  
> db.compactRange(columnFamily, true, 1, 0)
> -->
> db.compactRange(columnFamily, null, null, CompactRangeOptions);
>  
> NOTE: CompactRangeOptions extend RocksObject and as such should be closed to avoid leaking memory!
