I have a large csv file of lat/long points that I would like to import into Parse into a class that has already been created with existing lat/long points. Unfortunately parse does not allow you to import "Geopoints" with their CSV import tool. They only let you import that standard data sets. (Strings, Arrays, Booleans etc.) Does anyone know of a way to import them into an existing class? Thanks.

I want to read a single CSV file in a google bucket with pyarrow. How do I do this?
I can create a FileSystem object with gcsfs, but I don't see a way to provide this to pyarrow.csv.read_csv.
Do I need to create some sort of file stream from the file system? What's the best way to do this?
import gcsfs
import pyarrow.csv as csv
fs = gcsfs.GCSFileSystem(project='foo')
csv.read_csv("bucket/foo/bar.csv", filesystem=fs)
TypeError: read_csv() got an unexpected keyword argument 'filesystem'
Using pyarrow version 6.0.1
I'm guessing you are working with this doc. You're correct that the approach listed there does not work with read_csv because there is no filesystem parameter. We can still generally do this but the process is a bit different.
Pyarrow has its own filesystem abstraction. If you have a pyarrow filesystem then you can first open a file and then use that file to read the CSV:
import pyarrow as pa
import pyarrow.csv as csv
import pyarrow.fs as fs
local_fs = fs.LocalFileSystem()
with local_fs.open_input_file('foo/bar.csv') as csv_file:
csv.read_csv(csv_file)
Unfortunately, a gcsfs.GCSFileSystem is not a "pyarrow filesystem" but you have a few options.
The method gcsfs.GCSFileSystem.open can give you a "python file object" which you can use as input to pyarrow.csv.read_csv.
import gcsfs
import pyarrow.csv as csv
fs = gcsfs.GCSFileSystem(project='foo')
with fs.open("bucket/foo/bar.csv", 'rb') as csv_file:
csv.read_csv(csv_file)
I wanted to import data to my collection in mongodb atlas, and I was following the documentation: https://docs.mongodb.com/compass/beta/import-export/ but there is no "ADD DATA" and I don't know if Im using some other version or Im doing something else wrongly.
I need to import whole file which is json array.
The docs you referenced are for a future version of Compass. If you want to import from EJSON at the command line you can use mongoimport.
Here's the simplest syntax, but there are many variations possible.
mongoimport --db=users --collection=contacts --file=contacts.json
I am trying to import a small json file that contains various strings that the program uses.
I can do a successful import:
import * as dwSTRINGS from './data/strings.json';
But cannot seem to reference the variable dwSTRINGS.
How do reference imported variables?

It doesnt print any error just stop and does not insert anything.
I tried to import some data in json too but i dont know if i should import it like data or meta data.
As the title goes , I wonder if MongoDB has a data file format to import directly ?I know that mysql has "sql" file format for it to import directly .I am now in a project has the same requirement.Any one can tell me ?
MongoDB can import data using the mongoimport tool from JSON, CSV and TSV data format as you can see here
MongoDB internally represents data as a binary-encoded JSON (BSON), so importing and exporting in JSON format is really fast and intuitive
Of course.Mongodb use mongodump/mongoexport to export the data to outside files and use mongorestore/mongoimport to import data to its databases.more details , just reference to mongodb doc.mongodump and mongoexport ,mongorestore and mongoimport ,do have some differences .More details ,please refer to mongodb doc.
