> Currently, Cassandra relies on disks for data storage and hence it needs data 
> serialization, compaction, bloom filters and partition summary/index for 
> speedy access of the data. However, with persistent memory, data can be 
> stored directly in the form of Java objects and collections, which can 
> greatly simplify the retrieval mechanism of the data. What we are proposing 
> is to make use of faster and scalable B+ tree-based data collections built 
> for persistent memory in Java (PCJ: https://github.com/pmem/pcj) and enable a 
> complete in-memory version of Cassandra, while still keeping the data 
> persistent.
