--------------------------------
Summary: Build a Document Store on HBase for Better Query
Processing
Key: HBASE-6800
URL: https://issues.apache.org/jira/browse/HBASE-6800
Project: HBase
Issue Type: New Feature
Components: coprocessors, performance
Affects Versions: 0.96.0
Reporter: Jason Dai
Attachments: dot-deisgn.pdf
In the last couple of years, increasingly more people begin to stream data into
HBase in near time, and
use high level queries (e.g., Hive) to analyze the data in HBase directly.
While HBase already has very effective MapReduce integration with its good
scanning performance, query processing using MapReduce on HBase still has
significant gaps compared to HDFS: ~3x space overheads and 3~5x performance
overheads according to our measurement.
We propose to implement a document store on HBase, which can greatly improve
query processing on HBase (by leveraging the relational model and read-mostly
access patterns). According to our prototype, it can reduce space usage by
up-to ~3x and speedup query processing by up-to ~2x.
