In this session you'll learn about the design and implementation of a new open source general-purpose Java library that supports storing structured data in Cassandra. Instead of mapping the data to multiple tables like an ORM would or embedding data using serialization, this approach decomposes structured data of arbitrary complexity into separate columns of simple values, allowing the data to be retrieved or updated in parts using hierarchical paths. Implementations are included for Cassandra using both the Thrift and CQL3 APIs. In addition, Eric's experiences are shared regarding the challenges of using CQL3 vs. Thrift for schema-less data.
