Hello! I am quite new to Netlify. I am having a problem with MongoDB (specifically with atlas DB) and functions. Whenever I make a request to an endpoint that accesses the database, it times out after 10 seconds. This was not a problem when I was developing/testing it locally. I am aware that this is the maximum for functions level 0. I have also set the whitelisted IP to 0.0.0.0. Other functions that do not use/access the database work just fine. I just wanted to confirm whether the starting connection just takes a long time or something might be wrong with my code. Thank you! ---

Hey @andrewing! It’s very possible that your function is not able to complete its work in 10 seconds, or it needs more memory than [is available](https://answers.netlify.com/t/common-issue-functions-101-debugging/347). > **Functions timeout after 10 seconds, and are limited to 1024mb (1 gb) of memory by default.** They are deployed to AWS Lambda in their `us-east-1` region. Some modules, for example, [Headless Chrome](https://developers.google.com/web/updates/2017/04/headless-chrome), require the whole 1gb of RAM! There are custom settings available (up to 26 seconds runtime and 3Gb memory) which you’ll need to contact our support team - please post in the #Admin area of this forum to get our attention for this. Can you check your function logs and see if there’s any information there about duration or memory usage?

I set up a sample mongodb filled with their sample data and simply want to pull it to be used on my website. When I work locally via the netlify-cli I am able to properly query the database and return the value I’m looking for without error. It’s when I push the function up to my site that I begin to run into issues with it timing out. My code can be seen below (username and pw changed) /\* eslint-disabl… ---

As I mentioned in the [post](https://answers.netlify.com/t/fetching-mongodb-data-with-lambda-functions/11225) mentioned by @jen, for anyone who might come to this post after having problems with the timeout from the Netlify Functions while using MongoDB integration (I’m also using a Free server from MongoDB Atlas): Create indexes. MongoDB might take some time (more than 10 seconds) to look for a simple string with a collection with 5 documents and an index will fix that. If you’re using MongoDB Atlas, check this link to learn how to create index using the data explorer: [https://docs.atlas.mongodb.com/data-explorer/indexes/](https://docs.atlas.mongodb.com/data-explorer/indexes/) If you’re not using Atlas, you can check this link to create the index manually: [https://docs.mongodb.com/manual/tutorial/create-indexes-to-support-queries/](https://docs.mongodb.com/manual/tutorial/create-indexes-to-support-queries/)
