The HBase team is happy to announce the immediate availability of Apache HBase 2.0.0-alpha-1.
Apache HBase is an open-source, distributed, versioned, non-relational database. Apache HBase gives you low latency random access to billions of rows with millions of columns atop non-specialized hardware. To learn more about HBase, see https://hbase.apache.org/. HBase 2.0.0-alpha-1 is our first 2.0.0 release. It is a rough cut ('alpha') not-for-production preview of what hbase-2.0.0 will look like. It is what we used to call a 'Developer' release[1] meant mostly for devs and downstreamers to test drive and flag us early if we there are issues we’ve missed ahead of our hardening the 2.0.0 release. hbase-2.0.0 includes a fleet of new features that include a new assignment manager, means for keeping read and write path off-heap, in-memory compactions ('Accordion'), and more. We have been keeping a running doc on the state of 2.0.0 here [2]. There is much to do still (see aforementioned doc). We would appreciate any feedback especially on the new features whether comments or bug reports. The list of features addressed in 2.0.0 so far can be found here [4]. There are about 2500. The list of ~500 fixes in 2.0.0 exclusively can be found here [3].
