Notes on HBase 0.92

This is part of a four-post series, covering:

As part of my recent round of Hadoop research, I talked with Cloudera’s Todd Lipcon. Naturally, one of the subjects was HBase, and specifically HBase 0.92. I gather that the major themes to HBase 0.92 are:

HBase coprocessors are Java code that links straight into HBase. As with other DBMS extensions of the “links straight into the DBMS code” kind,* HBase coprocessors seem best suited for very sophisticated users and third parties.** Evidently, coprocessors have already been used to make HBase security more granular — role-based, per-column-family/per-table, etc. Further, Todd thinks coprocessors could serve as a good basis for future HBase enhancements in areas such as aggregation or secondary indexing.

*Examples include unfenced C++ extensions to analytic RDBMS or — which mattered more in the 1990s than now — “blade”/”cartridge”/datatype extensions to extensible RDBMS such as Illustra, Informix, Oracle, or DB2.

**Admittedly, in the current HBase community, a considerable fraction of user organizations fit the “very sophisticated”/co-developer template.

As for scalability and performance, it seems the advances there match clichés such as “low-hanging fruit” or Bottleneck Whack-a-Mole.

Overall, Todd says several tests have indicated HBase performance improvements of 60% or better, with some particular cases of course going much higher (up to 2 1/2X).

My whole HBase discussion with Todd was pretty short, actually; just one of several subjects in a one-hour call. But we did squeeze in one topic that wasn’t 0.92-specific — namely, what does HBase storage tend to be like? Notes on that included:
