GoHive: A Hive Driver for Go

Go programmers usually call the standard package database/sql to access databases. database/sql relies on database drivers to work with database management systems. A growing list of drivers is at https://github.com/golang/go/wiki/SQLDrivers, where we cannot find one for Apache Hive at the moment we wrote this package.

Walkthrough the Code

• driver.go

  As required by database/sql, driver.go defines type gohive.Driver that implements the database/sql/driver.Driver interface, which has a method Open. The init() method registers the type gohive.Driver.

• connection.go

  The Open method of database/sql/driver.Driver is supposed to return a connection, which is a type that implements the database/sql/driver.Conn interface. connection.go defines the type gohive.Driver that implements database/sql/driver.Conn.

  gohive.Driver also implements database/sql/driver.QueryerContext by defining method QueryContext to run queries and to return rows.

• rows.go

  rows.go defines type gohive.Rows that implements the interface database/sql/driver.Rows.

Access Hive through Thrift

For contributors who are curious how this driver talks to Hive via its Thrift interface, here is Hive’s Thrift service definition.

Running Hive in Containers

For the convenience of the development of this package, we provide Dockerfiles that install and run Hive in Docker containers.
