"text": "Greetings Realm folks,My name is Andrew Meyer, one of the engineers at realm-js, and I am making a guest post today in @henna.s Realm Byte column to help React Native users get started with our new library @realm/react. @realm/react is a module built on top of realm-js with the specific purpose of making it easier to implement Realm in React.I wanted to provide a quick example for React Native developers, to get an idea of how easy it is to get started using Realm using @realm/react. Therefore, I made an 80 line example of how to create a simple task manager using the library.You only need to have @realm/react and realm installed in your project and you will be good to go. If you aren’t using TypeScript, simply modify the Task class to not use types.Here is a breakdown of the code.Setting up and thinking about your model is the first step in getting any application off the ground. For our simple app, we are defining a Task model with a description, completion flag, and creation timestamp. It also contains a unique _id, which is the primary key of the Task model. It’s good to define a primary key, in case you want to reference a single Task in your code later on.We have also added a generate method. This is a convenience function that we will use to create new tasks. It automatically generates a unique _id, sets the creation timestamp, and sets the description provided by its argument.The schema property is also required for Realm. This defines the structure of the model and tells Realm what to do with the data. Follow Realm Object Model for more information.Here is the code for setting up your model class:The next part of the code is a necessary part in setting up your application to interact with Realm using hooks. In this code, we are calling createRealmContext which will return an object containing a RealmProvider and a set of hooks (useRealm, useQuery and useObject).The RealmProvider must wrap your application in order to make use of the hooks. When the RealmProvider is rendered, it will use the configuration provided to the createRealmContext to open the Realm when it is rendered. Alternatively, you can set the configuration through props on RealmProvider.Here is the code for setting up your application wrapper:Now that you have an idea of how to set everything up, let’s move on to the application. You can see right away that two of the hooks we generated are being used. useRealm is being used to perform any write operations, and useQuery is used to access all the Tasks that have been created.The application is providing a TextInput that will be used to generate a new Task. Once a Task is created, it will be displayed in the FlatList below. That timestamp we set up earlier is used to keep the list sorted so that the newest task is always at the top.In order to keep this code short, we skipped a few best practices. All the methods provided to the application should ideally be set to variables and wrapped in a useCallback hook, so that they are not redefinined on every re-render. We are also using inline styles to spare a few more lines of code. One would normally generate a stylesheet using Stylesheet.create.Here is the code for the application component:Here is the example in full, including all the required import statements.For more details on how to use @realm/react checkout our README and our documentation. If you are just getting started with React Native, you can also use our Expo templates to get started with minimal effort.And with that being said, what do you think about @realm/react? Any other examples you would like to see? We are working hard to make it easy to integrate realm-js with react-native, so let us know if you have any questions or feature requests!Happy Realming!",

However, I can’t use the Realm.List type as an argument to the data prop of FlatList.

We have added a flag to the RealmProvider in version 0.6.0 called closeOnUnmount which can be set to false to stop the Realm from closing if you are trying to do anything with the Realm instance outside of the component. Without setting this flag, as soon as the RealmProvider goes out of scope, the realm instance instantiated therein will be closed.\nIt’s important to note, that with realm instances that are instantiated and point to the same realm, when one of them is closed, they all close. We will address this in a future version of the Realm JS SDK, but for now, the closeOnUnmount flag can be used to workaround this.\nAnother note, any of the hooks will only work within components rendered as children of the RealmProvider. Anything done with a realm instance outside of this provider must be done without hooks. This includes registering your own change listeners if you want to react to changes on data, which the hooks handle automatically.\nLet us know if you have any other issues ",

Realm.open is async and more suited for a Realm configured with sync settings.At the moment we do not have a discord, but you are not the first to ask about this.

I am seeking advice and guidance on a data access issue that I am currently facing, and I believe this community’s expertise may be instrumental in finding a solution. I apologize in advance for the length of this post, but I want to provide a comprehensive background on the issue.Background: I am responsible for managing data access and reporting for different branches, each of which represents a distinct company within our organization. These branches have expressed a need for direct access to specific data for use in Power BI, enabling them to create their own custom reports and charts.Challenges: My primary challenge lies in providing these branches with filtered data that corresponds to their specific branch, ensuring data privacy and security. My goal is to empower them to create meaningful reports while maintaining strict access controls.Current Approach: I have attempted to address this challenge by developing a data API that can filter data based on the branch. While this has been successful on the data preparation side, I am struggling to understand how to connect this filtered data source to Power BI.Key Questions:I would greatly appreciate any insights, experiences, or suggestions that forum members can provide regarding this complex issue. Please share any relevant resources or step-by-step guidance, as I am dedicated to finding a secure and efficient solution that empowers our branches to harness the power of Power BI while adhering to strict data access controls.Thank you in advance for your valuable input, and I look forward to engaging in a fruitful discussion within this community.",

The docs for the restricted news feed state:changes don’t take effect until the current session is closed and a new session is started.I believe this is because we are effectively setting a new session role role for the user.The Swift SDK provides APIs to suspend and resume a Sync session. I believe that if you suspend and then resume Sync, that will trigger a session role change and the user should be able to sync the new comments. This may trigger a client reset, so you’ll want to set a client reset mode in your sync configuration. This would look something like:This should then trigger the realm to re-sync relevant comments based on the updated subscription.We do have some work planned in the future to improve this process, but I think this is roughly what you’ll need to do to handle it currently.",

As a result, the first and third queries would not work correctly with the parameters specified.Based on the query you’ve shared, you can utilise multiField indexes, as shown in the following example:Suppose we have the sample data:I have defined the index as:And the following query:will give you the desired output.For more details, please refer to the Construct the Query Path documentation.In case if you have further questions or concerns, please feel free to share additional info such as sample documents and the expected results, so community can help you better.Warm regards,\nAasawari",

Once enabled/disabled, are we supposed to do that again when we re-login in mongosh ?Once you invoke the enableTelemetry() or disableTelemetry() functions, the config file above will store your preferences locally so you don’t have to toggle it on/off each time you re-login.2.2. If I have disabled it, what’s the state when my team member logs-in in same database via different machine ? (is it disabled for him as well? or does he need to disable ?)As mentioned above, the setting is local so it will not affect your teammates using mongosh in a different machine. Their preferences will be stored locally in their machine.2.3. If I have disabled it, and when I login again next day. Does it remain disabled ?Since the setting persists in the config file, if you have disabled it, it will remain disabled unless you explicitly toggle it on again.2.4. If I have disabled it, when I restart mongod service, then what is the status of telemetry ? (is it enabled again or will it remain disabled ?)Restarting mongod will not affect this setting in mongosh since they are two different binaries/applications.Where are you seeing a telemetry message? Is it in a log file somewhere?Finally, mongosh also supports the global config file for disabling telemetry consistently on a given machine.

The practice seems to indicate that if the inner fails, the outer should rollback, which happens as you’ve described.Further reading I found interesting on this are here and here (not technology specific, mainly for the context on nested transactions).",

"text": "Hi @Engatta_Team and welcome to MongoDB community forums!!Firstly, $exists in MongoDB is the aggregation stage which filters out the results based on the availability of the filed name.\nThis does not filter the documents based of the field values. You can make use of $match stage if you wish to do so.From the information posted above, there could be two different ways to understand about facets.1. $facet as aggregation stage. In this case, the $facet categories the data in multiple dimensions to perform the query on which means it performs multiple aggregations within the same stage and process the output. If you are using $exits inside the $facet stage, it would filter out the results to be processed. You can visit the example for further information.2. $facet inside $search as an operator: This operator would groups results by values or ranges in the specified faceted fields and returns the count for each of those groups. This operator could be applied to String, numeric and Date fields which have been defined as StringFacet, NumericFacet and DateFacets respectively. You can visit the examples and the index definitions for usage of facets in the String Facets documentations.In your case, it sounds like you want to filter documents by the ObjectId value before faceting. To do this, you can use a $match stage first to filter the relevant documents by the ObjectId, and then apply the $facet stage to aggregate over those resultsHowever, if this is not what you are looking for, could you provide me the sample documents and the desired output from the documents. Also, please share the index query being created.Warm regards\nAasawari",

In a subsequent example, I see you used $date, which appears to be Extended JSON syntax (also unrelated to PHP).To clear up any misunderstanding, I would suggest you start by familiarizing yourself with the BSON Types in MongoDB. There is a particular BSON type (0x09) that corresponds to a UTC date time value, which is not to be confused with the Timestamp BSON type (0x11), which is used internally for things like replication.In the MongoDB shell, Date() and ISODate() can both be used to construct JavaScript objects that will encode as UTC date times in BSON. In the PHP driver, the MongoDB\\BSON\\UTCDateTime object serves that purpose.Independent of the MongoDB driver, PHP itself has a DateTime object, which represents a date with a timezone. Since the MongoDB date type assumes a UTC time zone, the PHP driver allows you to construct a UTCDateTime object from a PHP DateTime instance; however, the driver will not automatically convert a PHP DateTime into a BSON date for you. If given a PHP DateTime, the standard rules for encoding PHP objects to BSON will apply (i.e. only its public properties will be saved as document fields).How to specify a MongoDB ‘new Date()’ when using the PHP driver?Please review the examples on MongoDB\\BSON\\UTCDateTime::__construct(), which demonstrate constructing a UTCDateTime instances from an integer, DateTime object, and without arguments.If you are starting from a date string value, then you’ll always want to review DateTime::__construct() or createFromFormat(). Since the PHP driver allows construction of a UTCDateTime from a PHP DateTime, it does not reimplement the logic for parsing a date from a string.This works fine in Composer.Note that Composer is a package manager. I’m not sure if you meant to refer to the MongoDB PHP Library, which is distributed as a Composer package, but it helps to use to correct terms to avoid any misunderstanding.Lastly, my replies in mongodb/mongo-php-driver#187 may also be helpful to clear up some misunderstandings. That’s an old issue, but it pertains to some users attempting to use ISODate() and JSON syntax with the PHP driver.",

Security is the main concept here and you would not want free access to your database. The usual way is to have your own back-end API to communicate with your database and so keep your database credentials secure (as much possible as your host settings allows).Using Realm or Data API is best to use with your IoT devices as they mostly don’t have enough memory to put whole drivers. They can communicate with basic TCP requests to write to the database. As long as you keep those devices in safe places, you can have as many as you want to write to the database. or at least give them access to a very limited resource.Or you may do the same base access from the terminal anytime with tools like good old curl. Or write PoC API fast without going into driver details (Javascript or Python is great for prototyping). Same applies to front-end; for PoC purposes create temporary access points.",

"text": "Thank you for that detailed reply. That all makes sense and was how I thought the data api would work on the front end. My goal in finding a new way to connect to my database was speed more than anything else.The other option is to use the realm-web sdk and this would solve my problem of calling the db from the front end. However its a big js bundle as I learned in one of my previous projects. Downloading realm 132kb unminified just to establish a connection and send data/authenticate is a bit much.When i tried the data api, this is what I found:\nI used Atlas 3rd party http triggers as a proxy to call the DATA API, but under my tests in the past it takes about 3-4 seconds to return a response .The whole cycle using the data api takes about 2.5 seconds on the quick side.Realm SDK is much faster in my tests but the bundle is quite big.So I am going back to what I did in the past which is simply use AWS lambda HK region running the official mongo db driver, which connects directly to my database. When the function is warm i get results in under 50 ms. – I wish this was the same with the data api, but its up to 10x as long. I hope Mongo Atlas can figure this out. Even calling a cloudflare edge worker still results in the same delay when calling the data api (as its still in preview, the data api end points are only in a few regions)Sorry i went on a tangent, but duration and bundle size is our current problem, surely writing less backend code would come in super handy. Currently we using realm-web sdk for larger projects with good internet connections, but for smaller projects with mobile connections realm sdk is too much weight.Anyway thanks for your help,.",

We run collocated instances on our development/testing environments. We do build normally 3 replicas each on separate host so we follow the availability model. Now, how do we make sure each instance is using a determined amount of java and cache memory? The way mongodb allocates memory (50%) seems to be that the first instance to start will take over 1/2 of the memory available and the second or 3rd instance will take 50% of whatever is left, and so on.\nHow can we configure the memory consumption for each instance?",

"text": "Hi @An_Infinite_Loop ,It appears that the best way to somewhat replicate “relationships” is to use DBRef. Am I right in my understanding?Personally, I would not recommend using DBRef unless your use case specifically needs it. While DBRef (Database References) is one way to establish relationships between documents, it’s important to understand how it works and its limitations. As written in this Database ReferencesUnless you have a compelling reason to use DBRefs, use manual references instead.To resolve DBRefs, your application must perform additional queries to return the referenced documents.In summary, your understanding is accurate. DBRef is a way to create relationships between documents in different collections in MongoDB and is suitable for classic one-to-many relationships. However, you should also consider the potential performance implications and whether denormalization or embedding might be more suitable for your specific use case, depending on your read and write patterns.Additionally, I would recommend you to go through below resources to understand more about Data Modeling, Design and Patterns. This will help you design your schema in a way which will provide better performance and flexibility as per your application requirements.Have you ever wondered, \"How do I model a MongoDB database schema for my application?\" This post answers all your questions!Let me know in case you have any more queries regarding this, would be happy to help you!
