kandi X-RAY | mongoimport Summary

mongoimport is a Go library typically used in Utilities, CSV Processing applications. mongoimport has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

CLI and go library for importing data from CSV, JSON or XML files into MongoDB. You can also download pre built binaries from the releases page. For a list of options, run. Using the tool as a standalone CLI tool is great for quick loading of a few files. However, you might need more fine-grained control over what files are imported into which collection or perform additional pre/post processing (e.g. parsing timestamps). For this use case, we offer a very extensivle and modular API for configuring your imports. For more examples, see examples/.

You are right, the legacy (aka deprecated) mongo shell does not support extended JSON parsing. However, the new mongosh shell provides the EJSON class for exactly that.

QUESTION

faster mongoimport, in parallel in airflow?

Asked 2022-Jan-18 at 01:52

tl;dr: there seems to be a limit on how fast data is inserted into our mongodb atlas cluster. Inserting data in parallel does not speed this up. How can we speed this up? Is our only option to get a larger mongodb atlas cluster with more Write IOPS? What even are write IOPS?

We replace and re-insert >10GB+ of data daily into our mongodb cluster with atlas. We have the following 2 bash commands, wrapped in python functions to help parameterize the commands, that we use with BashOperator in airflow:

upload single JSON to mongo cluster

First of all "What is the current bottleneck with importing to mongo?" and "Is it (a) CPUs in our server / docker container " - don't believe to anyone who will tell you the answer from the screenshot you provided.

Atlas has monitoring tools that will tell you if the bottleneck is in CPU, RAM, disk or network or any combination of those on db side:

On the client side (airflow) - please use system monitor of your host OS to answer the question. Test disk I/O inside docker. Some combinations of host OS and docker storage drivers performed quite poor in the past.

Next, "What even are write IOPS" - random write operations per second https://cloud.google.com/compute/docs/disks/performance

IOPS calculation differs depending on cloud provider. Try AWS and Azure to compare cost vs speed. M10 on AWS gives you 2 vCPU, yet again I doubt you can compare them 1:1 between vendors. The good thing is it's on-demand and will cost you less than a cup of coffee to test and delete the cluster.

Finally, "If there's a parallel solution using python's pymongo" - I doubt so. mongoimport uses batches of 100,000 documents, so essentially it sends it as fast as the stream is consumed on the receiver. The limitations on the client side could be: network, disk, CPU. If it is network or disk, parallel import won't improve a thing. Multi-core systems could benefit from parallel import if mongoimport was using a single CPU and it was the limiting factor. By default mongoimport uses all CPUs available: https://github.com/mongodb/mongo-tools/blob/cac1bfbae193d6ba68abb764e613b08285c6f62d/common/options/options.go#L302. You can hardly beat it with pymongo.

ANSWER

Answered 2022-Jan-07 at 19:23

You've overwritten the mongo startup procedure with your own CMD, such that the Mongo server doesn't start anymore. Therefore, mongoimport will fail, and your container will exit.

Instead, just run the original Mongo image by itself with a volume mount, then exec into it, and run your import function. Afterwards, it'll still be running, and you can connect to it.

By the way, EXPOSE 27107:27107 isn't a valid expression.

This happens because you cannot have more than one CMD instruction in the Dockerfile. When you do, only the last one will be executed, this is by design. What you can do within you seed container -

copy the jsons to the seed container
copy a shell script containing mongoimport commands to the seed container
make CMD execute this script.

QUESTION

Change data type from string to date while skipping missing data

Asked 2021-Aug-24 at 10:30

The core collection (other collections in the DB refer back to this one) in my DB contains 3 fields with date information which at this point is formatted as strings like MM/DD/YYYY. Further, there are a range of documents for which this field contains missing data, i.e. "". I populated this collection by running the mongoimport command on a JSON file.

My goal is to convert these date-fields into actual ISODate data types, so as to allow filtering the collection by dates. Further, I want MongoDB to know that empty strings indicate missing values. I have read quite widely on this, leading me to try a bunch of things:

Trying a forEach statement - This worked, but only for the very first document.
