This has no meaning for a regular collection.The following comes from the db.createCollection() documentation for the size key:Optional. Specify a maximum size in bytes for a capped collection. Once a capped collection reaches its maximum size, MongoDB removes the older documents to make space for the new documents. The size field is required for capped collections and ignored for other collections.If you’re trying to create a capped collection, then you will need to determine your average document size and then multiply that by 500 to get an approximate value for size to hold the 500 documents. You can combine the size key with the max key to make sure you don’t have more than 500 documents in the collection, but you can’t guarantee a minimum number of documents unless you were to oversize the collection.If you’re trying to create a regular collection then you don’t need to do anything special to store 500 documents in the collection.

I would recommend installing the latest version of the 3.6 production release series (currently 3.6.17) so you have the latest bug fixes and stability improvements.

It makes it much harder to, for instance, comment on a specific line of output.Second, would you please clarify why you are building the now quite old 3.6 release, rather than a more modern branch like v4.2? And, if there is a specific reason for building a v3.6 series release, why are you building the .9 version, rather than v3.6.17, which is the latest bugfix release in the v3.6 series? You definitely want to be running the newest bugfix release out of any branch.Third, there are several pieces of information that will be required to make forward progress here. At minimum, please tell us your operating system distro and version, the version of GCC that you are using, how you obtained the source code (e.g. git checkout, tarball from the downloads site, something else), any local edits to the source code, and the complete SCons invocation that you used to try and build.Fourth, the error shown in the screenshot is what I would expect to see if the build was cancelled with ^C or similar. No compiler or linker error has been shown. Is it possible that something else on the machine is interfering with the build? Could you be running out of memory or some other resource?I also have some comments on the various tickets you mentioned.https://jira.mongodb.org/browse/SERVER-21317 is fixed in v3.6.9, so you should not need to include a dummy version.json file. What error did you observe when you didn’t provide the version.json file? Note that you can also explicitly set a version by adding MONGO_VERSION=x.y.z on the command line. However, this should not generally be necessary.It is fine to use --disable-warnings-as-errors if you are using a newer compiler than the official compiler version. On MongoDB v3.6, that is GCC 5.4. Note though that we do no in house builds or tests of the v3.6 branch with newer compilers, and we don’t guarantee that builds using other compilers will work. If it is possible for you to build with GCC 5, that would be preferred to using a newer compiler.The issue the user faced in SERVER-31439 was likely a broken local toolchain. SCons intentionally does not propagate the users shell PATH into the build, because it makes the build non-deterministic. If your g++ binary isn’t able to locate the linker it was configured to use without setting PATH, then the toolchain installation is likely broken.I think if you can follow up on each of the points above, we can get things set up so that you have a working build without needing to work around any particular issues.Thanks,\nAndrew", "username": "Andrew_Morrow" }, { "code": "[root@portal4 mongo-r3.6.9]# uname -a Linux portal4 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux[root@portal4 mongo-r3.6.9]# python --version Python 2.7.5[root@portal4 mongo-r3.6.9]# clang --versionclang version 3.4.2 (tags/RELEASE_34/dot2-final)Target: x86_64-redhat-linux-gnuThread model: posix[root@portal4 mongo-r3.6.9]# scons --versionSCons by Steven Knight et al.:script: v3.1.2.bee7caf9defd6e108fc2998a2520ddb36a967691, 2019-12-17 02:07:09, by bdeegan on octodogengine: v3.1.2.bee7caf9defd6e108fc2998a2520ddb36a967691, 2019-12-17 02:07:09, by bdeegan on octodogengine path: ['/usr/lib/scons/SCons']Copyright (c) 2001 - 2019 The SCons FoundationMongo Ticket SERVER-36206--disable-warnings-as-errorsMongo Ticket SERVER-31439python buildscripts/scons.py all --variables-files=etc/scons/propagate_shell_environment.vars --disable-warnings-as-errors[root@portal4 mongo-r3.6.9]# free -mtotal used free shared buff/cache availableMem: 11853 624 524 8 10704 11094Swap: 4095 0 4095[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py all --disable-warnings-as-errorsscons: Reading SConscript files ...Invalid MONGO_VERSION '', or could not derive from version.json or git metadata.

However, this should not generally be necessary.I had tried below command which resulted in unknown variable message MONGO_GITHASH but instead of removing MONGO_GITHASH from command line I added version.json\n[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py MONGO_VERSION=3.6.9 MONGO_GITHASH=none all\nscons: Reading SConscript files ...\nMkdir(\"build/scons\")\nscons version: 2.5.0\npython version: 2 7 5 'final' 0\nUnknown variables specified: MONGO_GITHASHThis was my mistake - the variable is called MONGO_GIT_HASH (note the extra _).Also git describe was not going to return any output as I had downloaded the code instead of cloning it. So opted for version.json workaround.The problem is that the github based archives don’t contain the version metadata, which is why you need to mess around with MONGO_VERSION and MONGO_GIT_HASH to make this work. However, the source downloads from the mongodb download site do contain the data already. Please try downloading the source from Download MongoDB Community Server | MongoDB instead. That will contain a pre-populated version.json.Alternatively, use MONGO_GIT_HASH, and it won’t try to call git describe.If your g++ binary isn’t able to locate the linker it was configured to use without setting PATH, then the toolchain installation is likely broken.If I don’t add PATH in SConstruct file I get below error:\n[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py all\nscons: Reading SConscript files ...\nscons version: 2.5.0\npython version: 2 7 5 'final' 0\nChecking whether the C compiler works... yes\nChecking whether the C++ compiler works... yes\nChecking that the C++ compiler can link a C++ program... yes\nChecking if C++ compiler \"g++\" is GCC... yes\nChecking if C compiler \"gcc\" is GCC... yes\nDetected a x86_64 processor\nChecking if target OS linux is supported by the toolchain... yes\nChecking if C compiler is GCC 5.3.0 or newer...no\nChecking if C++ compiler is GCC 5.3.0 or newer...no\nERROR: Refusing to build with compiler that does not meet requirements\nSee /root/mongoCompilation_TagCode/mongo-r3.6.9/build/scons/config.log for detailsPlease post the contents of the config.log.

I may be interested in switching over a project from SQL to NoSQL, but before I delve too deeply I wanted to get some opinions.My goal is to be able to store an entire Google Maps route in a database. This would consist of an array of LatLng objects. Several thousand LatLng objects. Is Mongo capable of storing an array of this size? Is it advisable? Should I find another path forward?A little background on what I am trying to accomplish. I am working on a ride share app. A user would be entering their departure point, destination point, and date. The database then returns all routes that match the date (as well as some other search criteria such as passenger number, etc). At this point, I need to determine which of the routes are within a particular distance to the departure and end points that the user entered.What I am doing currently is making an Google API call for each returned route, using the route’s start and end point. I then compute the distance to this route from the API result. The problem is that the API calls are slow. On average, about 0.2 seconds per call. If I could simply get the route returned with the database query, I can reduce the processing time quite a bit.So, is this possible using Mongo?? I should also add, that I am building the project using Laravel. Does anyone have experience running Mongo with Laravel? Is it easy to integrate? Are there other NoSQL options that might be better?Many thanks for any input.", "username": "Michael_Forcella" }, { "code": "", "text": "Hi, I think Mongo works very well for this use-case.

The complete task is that I implement a unique constraint on an arbitrary field of a collection. I understand that to do so, a proxy collection is needed. This documentation seems to explain that well; https://docs.mongodb.com/manual/tutorial/unique-constraints-on-arbitrary-fields/. The documentation you referenced is specific to creating additional unique indexes for a sharded collection, although this may not be clear from a direct link to the page. MongoDB does not support unique indexes across shards, except when the unique index contains the full shard key as a prefix of the index.If you are working with an unsharded collection, you can create unique indexes without the need for a proxy collection. What I don’t understand is if I need a “migrations” collection in order to keep track of migrations that have occurred for that proxy collection or if I even need migrations. Somehow I’m under the impression that schemas update based on the object that is inserted into the database. MongoDB does not have a fixed schema catalog, so there isn’t a strict requirement for all documents in a collection to have the same structure (or to keep track of migrations). You can impose schema validation requirements for insert/update operations using JSON Schema, but changing schema validation rules does not perform migrations of existing documents.Depending on your use case, it may make sense to implement a migration strategy if your code is expecting identical schema in all documents. However, with flexible schema you have more control over the impact of migrations (instead of being limited to the “all-or-none” approach of a fixed schema).For example, you could add a schema version to documents and migrate them incrementally when they are next read by your application (or as a background task). There’s also a $jsonSchema query operator if you want to find documents matching a specific schema pattern.Regards,\nStennie", "username": "Stennie_X" }, { "code": "", "text": "This is very helpful.

You can also check if a collection is sharded by calling db.collectionname.getShardDistribution(), which will report something like “Collection test.collectionname is not sharded.” for an unsharded collection.Sharding is an approach for distributing data across multiple servers (or “shards”). Sharding is typically used to scale deployments with very large data sets and high throughput operations, but can also be useful for workload isolation (for example Segmenting Data by Location or Tiering Hardware for Varying SLA or SLO). Collections in a sharded cluster can be unsharded (the default) or sharded.A sharded collection is partitioned based on a shard key index that you define based on one or more field values. Sharding enables horizontal scaling since each shard only has to manage a subset of the data for a sharded collection.From an application point of view, a sharded collection is a single logical collection: you can query a sharded collection without being aware of which shard has the relevant results. However, since each shard only has a subset of the data enforcing uniqueness values other than the shard key requires some extra consideration (per the link you originally referenced).If you are interested in learning more about MongoDB, there are free online courses available at MongoDB University and a few learning paths (Developer or DBA/Operations) with recommended courses to take.Regards,\nStennie", "username": "Stennie_X" } ]

When encrypting a command, the driver first sends the command to mongocryptd, which analyzes it and marks the fields that need to be encrypted. The marked version of the command is then sent to libmongocrypt to do the actual encryption.My guess is that you’re running the community version of the server. As noted in the mongo package docs (mongo package - go.mongodb.org/mongo-driver/mongo - Go Packages), automatic encryption is only available for the enterprise version of MongoDB. This is because the mongocryptd binary is only available on enterprise builds.If you are not able to use an enterprise build, you can disable auto encryption and do explicit encryption instead. The data will still be automatically decrypted, as the decryption process does not require use of mongocryptd. See mongo-go-driver/client_side_encryption_examples_test.go at master · mongodb/mongo-go-driver · GitHub and mongo-go-driver/client_side_encryption_examples_test.go at master · mongodb/mongo-go-driver · GitHub for examples of explicit encryption.– Divjot", "username": "Divjot_Arora" }, { "code": "", "text": "Thanks @Divjot_Arora,\nThe 2 links you shared were useful.Best!", "username": "Student_al_St" }, { "code": "", "text": "@Divjot_Arora,\nI have some follow up questions\nWhy is that (from the example on GH) it requires to first compile the code with a cse tag?

We require this build tag because this feature requires linking against an external C library. The build tag allows users who don’t need this feature to compile and use the driver without worrying about installing libmongocrypt. If you’re curious, this is done by keep two separate copies of the source code, each conditionally compiled based on the build tag. One copy has actual logic to interact with libmongocrypt and implement the feature and the other contains function stubs that panic if called. You can see this by running the script without specifying the build tag.As for the collections created, I believe both examples create two collections:encryption.testKeyVault: This is the key vault collection and is used to store the data key created by ClientEncryption.CreateDataKey. These data keys are used to encrypt/decrypt fields. Note that the key material for these keys is also encrypted using the master key. In the examples I linked above, this is localMasterKey. The key vault is necessary collection for client-side encryption.test.coll: This is the collection where the application stores its data. In the example, this data looks like {\"encryptedField\": <encryptedField>}.For your question about GridFS, can you provide more details? Do you want to delete the entire GridFS file (i.e. delete all of the chunks for the file and any other information related to it) after a TTL?If you have any follow-up questions about client-side encryption, it may be helpful to create a new topic with the #go-driver tag for the GridFS question.– Divjot", "username": "Divjot_Arora" }, { "code": "", "text": "Thank you,I will keep this thread for client-side encryption only and,\nYou said I will need to install an different (go) drive?", "username": "Student_al_St" }, { "code": "-tags cse", "text": "For client-side encryption, you do not need to install a different driver.

I thought from your previous response I needed a different go driver.I see that forcing the -tags cse isn’t a friendly way of using CSE. I’d imagine how it fits in unit testing.

If they’re not, the #cgo lines will try to link against libmongocrypt, which will immediately fail if the user has not installed libmongocrypt on their system. The idea was to make users who wanted this feature opt-in via the build flag so that users who don’t need it didn’t have to install libmonogcrypt for no reason. Additionally, there are certain Docker images that don’t have cgo support at all, so it’s important that any cgo-based features in the driver are not automatically compiled.For your point about always requiring compilation, I don’t think this is true.
