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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscribe@cassandra.apache.org For additional commands, e-mail: commits-help@cassandra.apache.org
