> [We used to have non-pooled buffer version of SegmentedFile(comment still exits)|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/io/sstable/format/SSTableReader.java#L434] for accessing SSTable from tools, but when {{BufferPool}} is introduced it seems disappeared.
> We can either disable {{BufferPool}} from tools or introduce {{Rebufferer}} that does not use {{BufferPool}}. I tend to avoid {{BufferPool}} at all since it is singleton and accesses {{DatabaseDescriptor}}.
