Abstract
A parallel database system processes database queries invoking a user defined function (UDF). The database query is specified in a database query language, for example, the structured query language (SQL) and the UDF is specified in a programming language different from the database query language, for example, C/C++. The UDF may include multiple phases. The parallel database system generates optimized code for the UDF. The parallel database system includes a leader node and a plurality of compute nodes. The database query processes one or more database tables such that each compute node processes a slice of each database table. The leader node sets up a global context structure and provides it to each compute node. The global context may be shared across multiple executions of the query. The UDF may be used for efficient execution of extraction, transformation, and loading of data from external systems.
