Ignite Queue (Documentation or Code defect)?
When creating an ignite queue without an CollectionConfiguration (null) I'm not getting the expected Queue or Exception as documented in the JavaDoc. But i'm getting a cache that is null. The documentation: -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Re: Ignite Queue (Documentation or Code defect)?
Great I see something went missing: Ignite ignite = Ignition.start(); IgniteQueue queue = ignite.queue("Queue", 0, null); ignite.close(); In the queue created above I expect it to throw an exception if the queue can not be fetched, instead it is giving me a queue that is "null". Check the JavaDoc: Will get a named queue from cache and create one if it has not been created yet and cfg is not null. If queue is present already, queue properties will not be changed. Use collocation for CacheMode.PARTITIONED caches if you have lots of relatively small queues as it will make fetching, querying, and iteration a lot faster. If you have few very large queues, then you should consider turning off collocation as they simply may not fit in a single node's memory. Params: name – Name of queue. cap – Capacity of queue, 0 for unbounded queue. Ignored if cfg is null. cfg – Queue configuration if new queue should be created. Returns: Queue with given properties. Throws: org.apache.ignite.IgniteException – If queue could not be fetched or created. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Hope someone pics this up. That the code is not behaving as the documentation is saying. (Not throwing exception when queue can not be fetched). -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Re: Ignite Queue (Documentation or Code defect)?
It’s a good catch, but I think this is one of the developer mailing list. I see the same behaviour. Arguably it’s consistent with the Ignite#cache() which returns null if the cache doesn’t exist.

Re: Ignite Queue (Documentation or Code defect)?
Could you please file a ticket in Ignite JIRA for 2.10 release? That's definitely an overlook in the current implementation. - Denis On Tue, Aug 18, 2020 at 9:57 AM Humphrey wrote: > Hope someone pics this up.
