https://community.blueprism.com/t5/Product-Forum/Daft-question-of-the-day-why-lock-queues/m-p/48172#M3755 This is probably a very daft question, but myself and a few other recently appointed developers have been playing around with different architectures, and have been encouraged to lock the queue prior to loading a queue and then reporting.<BR /><BR />I'm just wondering specifically why these queue locks need to be put in place? I understand that an item lock should be put in place so that if a process utilises multibotting, only one bot can process one particular item. But we've been able to load a queue with one process whilst another process has drawn something from that queue and processed it successfully without a lock. So where would locks need to be put in place if we're just dealing with a single process accessing a single queue? And why?<BR /><BR />Can somebody clarify this for me please?<BR /><BR />------------------------------<BR />John Hammond<BR />------------------------------ Tue, 11 Jan 2022 15:27:00 GMT john.hammond 2022-01-11T15:27:00Z https://community.blueprism.com/t5/Product-Forum/Daft-question-of-the-day-why-lock-queues/m-p/48172#M3755 This is probably a very daft question, but myself and a few other recently appointed developers have been playing around with different architectures, and have been encouraged to lock the queue prior to loading a queue and then reporting.<BR /><BR />I'm just wondering specifically why these queue locks need to be put in place?

The only reason I can think of to try and lock the entire queue is if you had a process that was trying to perform some sort of cleanup or administration of the queue which required it to be stable/consistent (no new adds, completes, deferrals). ​Otherwise, the built-in locking mechanism associated with <EM><STRONG>Get Next Item</STRONG></EM> should be sufficient IMHO.<BR /><BR />Perhaps someone else will chime in and tell me why I'm mistaken. <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span><BR /><BR />Cheers,<BR /><BR />------------------------------<BR />Eric Wilson<BR />Director, Integrations and Enablement<BR />Blue Prism Digital Exchange<BR />------------------------------<BR /> Tue, 11 Jan 2022 17:07:00 GMT https://community.blueprism.com/t5/Product-Forum/Daft-question-of-the-day-why-lock-queues/m-p/48173#M3756 ewilson 2022-01-11T17:07:00Z
