v1.0.0-beta.1

Amazon Neptune JDBC Driver Public Preview

The Amazon Neptune JDBC Driver is a JDBC 4.2 compliant driver (Java 8), which provides read-only JDBC connectivity for the Amazon Neptune service using graph query languages Gremlin, openCypher and SPARQL, as well as SQL.

When using SQL, the graph is represented in a table/columnar format and SQL queries can be executed. The driver supports a subset of SQL-92 along with some common extensions and supports SELECT statements of the general form:

SELECT [ DISTINCT ] { * | <projectItem> [, <projectItem> ]* }
   FROM <tableExpression>
   [ WHERE <booleanExpression> ]
   [ GROUP BY { <column> [, <column> ]* } ]
   [ ORDER BY { <column> [ DESC ] [, <column> [ DESC ] ]* } ]
   [ LIMIT limitNumber ]

projectItem:
    [ agg ]* [ <table>. ]* <column> [ [ AS ] columnAlias ]

The driver can be used to integrate with BI tools that support JDBC Drivers. For Tableau Desktop users a connector is available to use.
