![]() ![]() Repeat this process as desired to include additional areas of the map in the schema analysis. MongoDB queries can be substantially faster with proper indexes created on collections to meet the application needs of data sorting and filtering. Click and drag on the map to draw a circle containing the area of the map you want to analyze. for eg: if document 1 has and when trying to export collection it's only exporting Name fields. Mongo -quiet blog -eval 'printjson(db.posts.find().skip(200).limit(200 ).toArray())' > c:\progs\myPosts2. To define a location filter: Click the Circle button at the top-right of the map. How to export collection from MongoDB Compass while trying to export collection from MongoDB compass it's not exporting all data, it's only export fields that are present in all documents. If in the previous example exported the first 200 entries to myPosts1.json, to export the next 200 we would run: ![]() Using the find function on the collection, and playing with the skip and limit functions we can orderly dumb the collection content to different files each one limited to N objects. MongoDB Compass - I have multiple collections in a single database, how to export all collections into one. This command will take the first 200 objects in the collections, and print it to the myPosts1.json file. Mongo -quiet blog -eval 'printjson(db.posts.find().skip(0).limit(200 ).toArray())' > c:\progs\myPosts1.json In those cases we can turn to alternative export solutions, like, for example, printjson: So far so good, but there is a little caveat: the mongoexport command does not allow us to split the output to multiple files, meaning that if we are dealing with a quite large collections we may end up with an uncomfortably big sized file. You don't need to use Share Schema as JSON in Compass, instead, you should export your collection to JSON via MongoCompass, it's true and can be achieved via this option: (But you'll need to extract every collection one by one) But Mongo Compass isn't the correct way to export collection. Running the above command will result in the collection posts – from the database blog– to be exported to the myPosts.json json file. Mongoexport -collection=posts -db=blog -out=c:\progs\myPosts.json all sorts of import and export operations on your MongoDB database. If you have not already done so, analyze your schema: Select your desired collection and click the Schema tab. ![]() This is useful for sharing your schema and comparing schemas across collections. MongoDb offers a handy tool – mongoexport– that allows us to export a MongoDB collection to a json file: You can export your schema after analyzing it. ![]()
