Testing workflow/task with priority

[shrimank]

In the latest code of netflix conductor added support for priority for workflow. Need to understand how priority works with workflow/tasks when startWorkflow invoked.

I have tested with simple workflow, just calling an http task. submitting 3 workflows with different priority, but the conductor server executing those workflows in order of submission(since you are scheduling the workflow for later some time).

Few More details:

**I have followed below steps to check the priority testing: 1.Registered Task 2.Registered Workflow(SIMPLE) 3.Created Worker and started polling the registered the tasks.

Then, submitted 5 curl request to start the workflow with different priority(0-99) (used endpoint which accepts priority in query param),. But the worker is polling the task & getting in the order of submission.

[ What are you doing here in the class RedisDynoQueue.class method public List push(final List messages) with priority how it set the priority to the message here.

double priority = message.getPriority() / 100.0;
double score = Long.valueOf(clock.millis() + message.getTimeout()).doubleValue() + priority;
String shard = shardingStrategy.getNextShard(allShards, message);
String queueShard = getQueueShardKey(queueName, shard);
quorumConn.zadd(queueShard, score, message.getId());

]

Please need your help to understand and implement the priority with workflow.

any updates on this item? I am also looking at the same code and cannot figure out how message priorities are being leveraged

maybe need make score to double looks like priority.[clock.millis() + message.getTimeout()]
