User Guide Overview Tasks ○ Executing Tasks o Workers Guide o Periodic Tasks ○ Sets of tasks, Subtasks and Callbacks ○ HTTP Callback Tasks (Webhooks). o Routing Tasks o Monitoring and Management execution units, called tasks, are executed concurrently on one or more worker nodes using multiprocessing, Eventlet [http://eventlet.net/] or gevent [http://gevent.org/]. Tasks can execute asynchronously or synchronously (wait until ready). Celery is used in production systems to process millions of tasks a day. Celery is written in Python, but the protocol can be implemented in any language. It can also

the maximum vector comes from, or how many JIT functions are created and total time spent in JIT tasks. This information can be helpful when tuning JIT or debugging a timing problem. Run EXPLAIN (ANALYZE schema, and each RETURNS TABLE. ## Using a Parallel Retrieve Cursor You will perform the following tasks when you use a Greenplum Database parallel retrieve cursor to read query results in parallel from PL/Container Docker images • Test the PL/Container installation The following sections describe these tasks in detail. ## Prerequisites - For PL/Container 2.1.x use Greenplum Database 6 on CentOS 7.x (or
