Developing Client Apps - JSON Tables

As part of its support for JSON tables, MapR-DB implements the OJAI API library. This section describes how to use MapR-DB's implementation to develop client applications that access JSON tables.

Note: Filters used with Scan operations support regular expressions. When you filter scans on MapR-DB tables, you can use regular expressions that comprise the Perl-Compatible Regular Expressions (PCRE) library as well as a subset of the regular expressions that are supported in java.util.regex.pattern. See HBase Java Regular Expressions Support for a list of supported regular expressions.
