SAP Sybase IQ includes a UDF API that you can use to build MapReduce components, which can be used for Hadoop integration. The SAP Sybase solutions store has examples of Hadoop integration.
Apache Hadoop is a MapReduce implementation. Hadoop is a Java software framework that automates scheduling of map and reduce jobs.
SAP Sybase IQ supports Hadoop-like parallel scheduling using Table Parameterized Functions (TPFs), a class of external user-defined functions. TPFs accept arbitrary rowsets of table-valued input parameters, and can be parallized in a distributed server environment. You can specify partitioning and ordering requirements on the TPF input. As a developer, you can use TPFs to exploit the MapReduce paradigm from within the database server, using SQL.
For TPF fundamentals, see the User-Defined Functions guide.
