RabbitMQ Consumer Prefetch value

jigar patel 3 months ago in Server / Execution updated by Njabulo Nxele 1 month ago 2

Hi Team, there is one suggestion to improve RabbitMQ consumer performance. We can divide the load with multiple consumer by specifying prefetch count value. If we are not specifying prefetch value that means single consumer have unlimited buffer means single consumer will pick all the data from queue.

Prefetch meaning "prefetch simply controls how many messages the broker allows to be outstanding at the consumer at a time. When set to 10, this means the broker will send 10 message, wait for the ack, then send the next."

References : 

Suggestion : Add prefetch configuration in trigger section of warewolf studio (i.e like trigger concurrency)

Please let me know if you need more help to understand.

For each loop issue: All Recordset index values not passing into child workflow

Ashley Lewis 8 months ago in Server / Execution updated by Siphamandla Dube 8 months ago 2


I have noticed that All the values of recordset are not passing into child workflow for each loop. I have checked this same behavior into the Select & Apply tool and it's working fine.

Please check the sample attached workflows & issue into screenshot.

It looks like the For Each is getting confused with 2 different recordset inputs: User(*) and Benefit(*)

Gandalf 5 months ago

Change For Each to use No. of Executes = 3 and see different result. This is from the tool handeling the replacement of * differently and incorectly.

Yogesh Rajpurohit yesterday at 9:13 a.m.

We have checked and found that the sequence of BenifitID in User Payload is incorrect so we changed the sequence and checked the result. Output is coming properly.

Attached are the Edited Workflows.

Warewolf-2.6.4: Trigger: On Local environment trigger is not picking the data from Rabbit MQ in most cases.

maya khambhayata 12 months ago in Server 0

Discussion-20211022_124100-Meeting Recording.mp4 in Warewolf-2.6.4 version, I have created 4 triggers in local environment and set the concurrency to more than 1. It created the queue in RabbitMQ. While pushing the data to queue in RMQ. It is not picking data most of the time. I have to edit something in trigger and save again. For example i have to change concurrency from 2 to 3 OR 3 to 2. then only trigger is picking data from RMQ. Also checked with other team members too. They are also facing same issue. Here I am attaching video recording for same.

Date Time and Debug not correct

Hagashen Naidu 2 years ago in Server / Execution 0

Please see attached workflow. When passing the following JSON as input:

"dateTime": "2020-04-14T09:20:18.982Z"

Even though the JSON is valid and I have specified the DateTime Input Format correctly when I debug I get an error that the Input String is not in the correct format. However when I 'View in Browser' it does not show an error. Furthermore the debug input of the tool does not show the input due to the error.


Date Time Issue.bite

PS. I got this to work by making the input format my current system format as it turned out, internally the Newtonsoft de-serializer interprets the DateTime into the system format. This is however hidden from user and would be difficult to find.

I think showing the Debug Input values would help the user see what value was actually being used and then they could adjust the format based on that. There is a case for saying that the format should not have changed without me explicitly doing so.
