> 1. Kafka + storm will build inverted index in memory. These index will be
> inserted into hbase by batch (e.g. every 5 minutes).
> 2. The inverted index in hbase will keep the short term data (e.g. 7 days).
> These index will be converted into data cube by batch (e.g. every 7 day).
> 3. The data cube in hbase will keep the long term data.
> 4. Query engine will decide to use inverted index or data cube in hbase by
> time range. In future, the query engine can also use the in-memory inverted
> index in storm that can reduce the data latency from minutes to seconds.
