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

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
