Hi, We would like to announce DELI, a research prototype for secondary index on HBase. DELI is research work from Syracuse University with collaboration from Georgia Tech and IBM Research.
DELI currently supports global indexing on HBase, but generally applicable to any NoSQL that uses LSM tree for persistence. The code is shared on github: https://github.com/tristartom/nosql-indexing DELI stands for "DEferred Lightweight Indexing". The following design makes it unique: - follow the log-structured design that all writes must be append-only. - couple the *index-base-table sync-up with compaction*. Details can be found in the following research paper published in CCGrid 2015: http://tristartom.github.io/docs/ccgrid15.pdf We are grateful for the HBase community, and any comments/suggestions are appreciated.
