> 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.
