Once authenticated you can use the getAuthResponse method on the User returned from the Google Playform Library (or simply the idToken property on the user in case you use the react-use-googlelogin package) to get the OpenID Connect ID Token.This token can be used when authenticating towards MongoDB Realm (via Realm.Credentials.google) as of Realm Web v1.1.0 which will be released shortly.I hope that we’ll be able to make a detailed example app or guide available soon, outlining the steps required to get Google OAuth via OpenID Connect setup correctly.Please let me know if I need to dive deeper into some part of my answer above \nHappy coding!", "username": "kraenhansen" }, { "code": "import { Credentials } from \"realm-web\";\nconst credentials = Credentials.google(\"google-id-token-goes-here\");\n", "text": "FYI: Realm Web v1.1.0 with support for passing in the OpenID Connect id token was just released.", "username": "kraenhansen" }, { "code": "", "text": "Awesome timing.

The dynamic loader should find libraries in /usr/local/lib64 and indeed the output of ldd indicates that it is finding libraries in /lib64. Given that it is not finding them automatically, getting the loader to find libraries in /usr/local/lib64 may require modifying your system’s /etc/ld.so.conf.

Unfortunately, I don’t see an easy way out of this since it’s tied to the notifications mechanisms in the core database. As a workaround, you can probably manually raise propertychanged for the root model when you return to the parent page. Something likeThat way, every time your page comes into view, the VM will force a redraw, which will cause it to pick up any changes that happened in the child page.Alternatively, if you don’t need a Save/Cancel button, you can let the UI drive the updates - that way every change is going to get persisted as soon as the user makes it and PropertyChanged notifications will be raised immediately.Regarding the “Cannot modify managed objects outside of a write transaction.” error - this is thrown when you try to set a property on an object while the Realm is not in a write transaction.

When the binding engine invokes the setter (e.g. in response to changes from the UI), we check existing transaction, and if none exists, we wrap the set value call in an implicit transaction.With compiled bindings, the binding engine no longer looks up properties using reflection, so it invokes the setter directly, thus skipping all of our custom logic.

This typically happens when client applications do not properly close their connections, or with Java in particular, that relies on garbage collection to close the connections.Additional RAM may be allocated for in-memory processing such as aggregation or in-memory sorting.

If you are following the in-place upgrade approach, make sure you read the upgrade steps and compatibility changes for each major release.

For a general comparison after upgrading or restoring your data, I would look at the db/collection/document counts and the data size which should be consistent.Assuming “db size” is measuring the storage size of your dbPath, the change you observed is likely due to MMAPv1 Record Allocation Behaviour Changes in MongoDB 3.0 which removed support for the legacy dynamic record allocation strategy.Earlier versions of MongoDB supported a dynamic record allocation strategy (variable sizes with padding factor for document growth) which was the historical MMAP default for new collections created prior to MongoDB 2.6. The dynamic allocation strategy could result in fragmentation and excessive storage use over time, and it was replaced with Power of 2 Sized Allocations. The new Power of 2 allocation strategy enabled better reuse of disk space with MMAP, but may preallocate more initial space depending on the size of your documents.Current server releases aren’t using semantic versioning so the first two digits of each release series are significant (2.4, 2.6, 3.0, …) rather than comparing 2.x versus 3.x (see MongoDB Versioning). The MMAP storage engine version is associated with a server release, with the general expectation that patch releases (x.y.z) do not introduce and backward compatibility changes but major releases (x.y) may. Any changes are documented in the release notes.That may be helpful when considering why the in-place upgrade path currently doesn’t support skipping one or more successive major releases.Note: the server versioning scheme will change starting with MongoDB 5.0 in 2021: Accelerating Delivery with a New Quarterly Release Cycle, Starting with MongoDB 5.0.Regards,\nStennie", "username": "Stennie_X" }, { "code": "", "text": "That’s the difference in allocation, that’s the difference in size.Thank you very much.And I’m really excited and excited to hear that 5.0 will be released next year.", "username": "Kim_Hakseon" }, { "code": "", "text": "This topic was automatically closed 5 days after the last reply.

[ { "code": "", "text": "Our app used realm cloud before for a live synchronization feature for realtime collaboration such as depicted in this early realm image video.. Unfortunately we realized that the speeds we can achieve with a M10 cluster in our region over the networks are far worse than the experience we had before with Realm. e.g. synchronizing the typing of a text took 1 second to be synced from one client to another via realm cloud. Now with MongoDB Realm, we experience delays of about 10 seconds as well as inconsistencies in the time, even on a cluster with no load.Regarding this issue I have the following questions:Are there plans to optimize this or is it in the nature of the replicated mongodb clusters, that syncs will take their time to arrive?What steps could an app developer do to optimize, e.g. only sync/write to the database after n keystrokes/points drawn.How will frequent writes, e.g. updating a string on every keystroke (e.g. “H, He, Hel, Hell, Hello” in a short timespan. affect the size of the database ( that includes history)", "username": "Christian_Huck" }, { "code": "", "text": "@Christian_Huck Thank you for your post. We realize that the sync performance right now leaves much to be desired, which is why this quarter’s product plan is almost exclusively dedicated to improving sync performance, its also why we are still flagging Realm Sync as Beta. Our initial implementation focused on correctness and bug fixing, and now that the sync stability has improved we are changing gears to performance. The underlying architecture of the new Realm Sync is such that we intended to not only meet, but far exceed performance in the legacy Realm Cloud - the legacy Realm Sync architecture had backed ourself into a corner with some of our decisions, and would have necessitated a large refactor anyway.That being said, even with the planned performance improvements, there is always going to be best practices that the user should follow in order to increase throughput. One is to always batch writes as much as possible on the client, if your client is writing a lot of data, then we recommend a rule of thumb of 10k objects per transaction. Another is to try to not store a lot of blob or binary data in realm and replicate via sync - this is because sync works using an operations log, essentially it is a copy of the state, one for actual state and one for the operation + payload. You could imagine that an implementation that simply inserted and deleted a 1MB photo over and over again would blow up your realm sync history log, reducing performance. The last thing to keep in mind, is that if your app has a shared writable data between groups of users you should design your partitioning strategy to maximize throughput. This is because OT, our conflict resolution algorithm, can generally be the largest factor when it comes to throughput, and this algorithm is applied per partition. The more users you have writing to a partition, the longer these users have been offline, and the amount of changes they have accred locally before syncing to the server-side are all variables which will decrease performance. If you are running into this then you should look to create more partitions and reduce the amount of users per-partition.I’m not sure on your specific use case but feel free to open up a support ticket and we can look at your particular use case and implementation and either make suggestions on how to improve performance now, or make sure that your specific use case will be helped by future work we are doing on the sync server.As an example, we recently had a support case where a user was collecting sensor data every 100ms and wanted this data to replicate to another sync user in realtime. However, the developer was performing a write operation every 100ms (per-sensor reading) which caused the user receiving the data, their sync time would continuously lag behind, and the lag time would increase the longer the sync write user continued to write. What we did was instead batch those sensor readings to perform a sync write operation on the client around every 2-3 seconds. This enabled the receiving sync user to receive the data in constant time - there was no longer any steadily increasing lag time. I hope this helps", "username": "Ian_Ward" }, { "code": "", "text": "@Ian_Ward thanks for the uodate. Meanwhile, moving to a production environment, our speed has improved. One thing we did is migrating from mutable collection sets to inverse relationships (Dog->Owner instead of Owner -> dogs).I will open a support ticket still to see if we can improve our speed further and optimize our writes.", "username": "Christian_Huck" }, { "code": "", "text": "This topic was automatically closed 5 days after the last reply.

Atlas does not include support for hosting application backends like Node.js, however there is an integrated serverless platform called MongoDB Realm which you can use to run backend data services including functions and triggers. MongoDB Realm has various SDKs (including a Web SDK you can call from JavaScript and TypeScript applications) that enable you to write client applications interacting with backend data services which are written in JavaScript. MongoDB Realm’s serverless functions support using a subset of Node.js packages as External Dependencies.cPanel is a web hosting panel for managing hosted applications, and is commonly available on shared or managed application hosting services. You can use cPanel to manage your application environment and connect to a MongoDB Atlas database cluster. However, I’m not aware of any specific integration (or need for integration) with Atlas. You should just have to configure your Atlas IP security and use the standard approach to Connect via a Driver. If you are running an application server, you will generally want to choose an Atlas cloud provider & region which is close (by network proximity) in order to minimise network latency for application requests.If you’re having trouble connecting to Atlas, there are some great Connection Tutorials in the documentation and a guide to Troubleshooting Connection Issues.You can also ask for feedback and suggestions in the community forums.Regards,\nStennie", "username": "Stennie_X" }, { "code": "", "text": "This topic was automatically closed 5 days after the last reply.
