Also, my skill with aggregation queries is rusty. I believe I must create separate aggregation queries: one for mbps and one for iops. The reason for separate aggregation queries is because you have to sort the documents in a sort stage prior to an actual calculation for percentile. So there will be one aggregation query for iops which sorts the values in a sort stage. A totally separate aggregation is needed to sort the values for mbps in its own sort stage.I could have spent time experimenting with this, but I had some other things to do. I will try to experiment over this week and do my best, but others with more skill and experience than I could offer really good suggestions to you.

Swift driver is very important.Can you elaborate on the sort of GUI usage you are thinking of?I’ve worked with a few of your team members in the past and after about 45 emails and a lot of trial an error they were able to get a macOS app to build. However, that app was a stripped down command line app with no user interface - and even at that it had all kinds of compile errors and really didn’t work - but it did build.So the mention of GUI;It was very frustrating for us that once we were able to get the app to build, it was not really functional and wasn’t a base app to build on as development progressed because it has no graphical interface. e.g. If you fire up Xcode and build a new macOS project, right out of the gate you can run it and will see a blank window. While we could spend a LOT of time trying add the GUI components back into the command line app, it just seems backwards. Our suggestion is to start with a standard app (Xcode->New Project->macOS app) and then integrate mongo into it.Also, the use of SPM in this case is well, a bad way to go (IMO). It may be the ‘future’ but for now, if a developer wants to create an app, Cocoapods is a pretty bulletproof, tried and true way to integrate your API into an app.Maybe I am overstating things but try it yourself; walk through your guide and try to build a macOS app which includes MongoDB and provides a GUI.but I’ve noticed you are very active in the Realm community.I am and always try to give back to the developer community.Part of the reason I am mentioning this (macOS getting started) is that we banked on Realm a few years back in the hopes it would become a mature multi-user(tenant), multi-device back end for our product.

In fact one of the realm engineers, in response to a Feature Request to have record/object locking was:Apart from that, I don’t see the real-world benefit of having such a system in placeSo we are looking to move away from Realm to another platform that is better suited and Mongo has many of the features we need.

SwiftPM is used pretty exclusively in that community, which is why we chose to focus our packaging efforts there.\nRegarding homebrew usage when installing, that will go away in our next release, as we’ve now vendored the C driver into the Swift driver and it is built by SwiftPM along with the Swift code.Using the driver directly in a GUI desktop application to talk to a remote server isn’t a use case we’ve had requests for outside of yours; a more common architecture is to have a backend server which sits between your application and the database.

How is that done?Hi Norman,What are you trying to achieve?The localLogicalSessionTimeoutMinutes parameter needs to be set for each mongod instance in a deployment and is not a parameter currently available in the Atlas UI or API. I believe this is only suggested for testing as there will be unexpected consequences if the value isn’t set consistently in a deployment. This parameter determines when an inactive session is eligible to be cleaned up by the server so is generally a housekeeping parameter rather than a tuneable for performance or privacy.Regards,\nStennie", "username": "Stennie_X" }, { "code": "", "text": "Thanks Stennie for the reply!I guess the mystey is solved, I was wondering where in the Atlas UI it was located I’m trying to achieve > meet a requirement our security team, as thy are asking if we can reduce the time out for inactive sessions to 15 mins, as the default is 30 mins.So as long as the deployment is consistent across all replicas/shards for the timeout then it would be considered SAFE?", "username": "nchan" }, { "code": "end_session()", "text": "Hi @nchan,If you want to end your sessions earlier (rather than waiting for the inactivity timeout) you can explicitly call the client end/close session method.

Since Atlas is a managed service ,I do agree it’s best not to diverge for the “standard” setup and have any custom configurations. This feature is available onPrem, with some caveats so I’ll wait to hear back from support.Internally for us it’s a “check box” for security reasons that we meet for a security audit, we can configure things to ensure disconnect from applications/tools. However multiple variables such as different tools, and code bases. So the initiating a disconnect from the database when there’s inactivity helps cover things missed.thanks again for the reply!", "username": "nchan" } ]

This is preferred over calling getMode, which will be deprecated in a future release.MongoDB\\Driver\\Session now exposes more detailed transaction information. Instead of only exposing whether a transaction is running, the current state of the transaction can now be obtained using the getTransactionState method.

On 64-bit systems, this method will always return an integer value.The --with-libbson and --with-libmongoc configure switches have been deprecated.

The “advertising” was effective even if it felt a bit blatent at times)I’d also like to note the same thing that was addressed - the venue felt far too small. Even standing room didn’t feel like enough in some of the sessions.Additionally, the lunch was a clever idea with food trucks, but none of the folks who attended the GraphQL talk (which I personally think was the best! Very informational, even outside of the Mongo uses. Great intro) were realistically able to get lunch.
