Bugfixes and Stability
This release of Galaxy features fewer user-facing changes, as a huge amount of
Galaxy release 21.09 will ship with a new web framework (fastAPI),
Celery task queue and process management using Circus.
You can preview this new stack now by running APP_WEBSERVER=dev ./run.sh.
Celery for background tasks
Galaxy can now run certain tasks in the background. The Celery workers are
currently not required, but if activated can perform certain long-running tasks,
such as creating history export archives. Celery tasks will bridge the gap between
rapid requests that can be handled during a web request and jobs that require extensive
and relatively slow setup.More robust selection of job handlers
Job throughput can be increased by starting Galaxy with multiple external job
handler processes. Jobs were traditionally assigned to a job handler process
by the web handler or workflow handler process that created the job. Since
Release 19.01 Galaxy has supported additional mechanisms that use database
serialization techniques to let job handlers assign processes to themselves.
This mechanism is more robust and doesn’t require that all job handler
processes be alive and known by the web handler process. Galaxy now determines
the best method for assigning jobs based on the database in use, if the assignment
method is not set explicitly. Older job assignment methods will be removed in Galaxy
release 21.09. For more details see the Job Handler Assignment Methods section
of the Galaxy documentation.
