Welcome
This is the Cascading.JDBC module.
It provides support for reading/writing data to/from an RDBMS via
JDBC drivers when bound to a Cascading data processing flow.
INSERT and UPDATE are both supported during sinking. Custom SELECTs
can also be used during sourcing.
Cascading is a feature rich API for defining and executing complex,
scale-free, and fault tolerant data processing workflows on a Hadoop
cluster. It can be found at the following location:
http://www.cascading.org/
Building
This release requires at least Cascading 1.0.1. Hadoop 0.19.x,
and the related HBase release.
To build a jar,
> ant -Dcascading.home=... -Dhadoop.home=... jar
To test,
> ant -Dcascading.home=... -Dhadoop.home=... test
where "..." is the install path of each of the dependencies.
Using
The cascading-jdbc.jar file should be added to the "lib"
directory of your Hadoop application jar file along with all
Cascading dependencies.
See the JDBCTest unit test for sample code on using the JDBC taps and
schemes in your Cascading application.
You must also include a JDBC driver library for your database.
