Subject [jira] [Created] (CASSANDRA-13981) Enable Cassandra for Persistent Memory
Date Mon, 30 Oct 2017 04:48:02 GMT

------------------------------------------

             Summary: Enable Cassandra for Persistent Memory 
                 Key: CASSANDRA-13981
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13981
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Preetika Tyagi
            Assignee: Preetika Tyagi


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.
