HBase features

Let's see the major features of HBase that make it one of the most useful databases for the current and future industry:

• Automatic failover and load balancing: HBase runs on top of HDFS, which is internally distributed and automatically recovered using multiple block allocation and replications. It works with multiple HMasters and region servers. This failover is also facilitated using HBase and RegionServer replication.
• Automatic sharding: An HBase table is made up of regions that are hosted by RegionServers and these regions are distributed throughout the RegionServers on different DataNodes. HBase provides automatic and manual splitting of these regions to smaller subregions, once it reaches a threshold size to reduce I/O time ...
