WebUsing compression or encoding is a must. Both SNAPPY and FAST_DIFF are good all around options. FAST_DIFF encoding is automatically enabled on all Phoenix tables by default, and almost always improves overall read latencies and throughput by allowing more data to fit into blockcache. WebHBase supports several different compression algorithms which can be enabled on a ColumnFamily. Data block encoding attempts to limit duplication of information in keys, taking advantage of some of the fundamental designs and patterns of HBase, such as sorted row keys and the schema of a given table.
