Parallelization in Talend

You can achieve Parallelization in Talend in 2 ways.

1. Running SubJobs in Parallel by using the Multi-threaded Executions
• Enabling Mulit-threaded Execution is hidden in the Jobs view of the studio.
• Also note that enabling multi-thread on a single processor could hurt the performance
2. Using the tParallelize component of Talend.
• The tParallelize component is an Orchestration component.

Screenshots of a simple sample Job running as a single thread, multi-thread and with tParallize are shown below.
