Apache Phoenix is an HBase SQL driver. Phoenix enables HBase to be accessed through JDBC and converts your SQL query to HBase scan and corresponding actions.
Compatibility:
Phoenix 2.x-HBase 0.94.x
Phoenix 3.x-HBase 0.94.x
Setting Purpose: Use Hbase to use more like relational database, Hbase itself does not have select, delete, where command, type Phoenix can realize this function.

Description: The Phoenix query engine translates SQL queries into one or more hbase scan and orchestrates execution to produce a standard JDBC result set. Directly using the HBase API, the co-processor and the custom filter, the performance magnitude is milliseconds for simple queries, and the performance magnitude is seconds for millions.

What is Phoenix Phoenix's team summed up Phoenix in a nutshell: "We put the SQL back in NoSQL" means: We put SQL into NoSQL again. The nosql here refers to HBase, which means that you can query hbase with SQL statements, and you might say, "Hive and Impala are OK." ”。 But Hive and Impala can also query text files, and Phoenix's feature is that it can only find hba

Overview
HBase is suitable for storing a large number of NOSQL data that require low relational operations, and is not designed to directly use native PAI to perform conditional judgments and aggregations that are commonly used in relational databases. HBase is excellent, and some teams seek to provide a more general developer-oriented operation on HBase, Apache Phoenix
