Apache HDFS Cache Store

Create an Apache HDFS cache store. Perhaps using the Parquet file format. Perhaps using a similar approach to HBase (WAL/memtable/SSTable). This will not only allow for durable data, but for the data to be processed using Apache Hadoop components (e.g. Hive / Cloudera Impala).

Tighter integration with Apache Hadoop allows for hybrid architectures with ISPN.
