MongoDb aggregation 16MB buffer size limit

+2 votes

Please tell me how can we resolve this issue, we are using aggregation and size of docs become greater than 16MB. We also tried "ALLOWDISKUSE = TRUE" but still its throwing same error.

We are using php to fetch data greater than 16MB. Let me know if you needed more info.

Change your aggregation so you are not constructing documents bigger than 16MBs.
We cant change aggregation, as data will grow, of-course we will have more data, we need some solution for this, not change of aggregation.
Can you not use $out stage to write the output data to a separate collection.

We are using mongo DB in a single node. I understand that this is not MongoDB is intended to do. But due to the sophistication of mongos querying and other architectural/ business reasons we have chosen MongoDB. We are facing an issue now. We would be happy to get it resolved with your help.

We have to limit the memory utilization of MongoDB.

WindowsVersion: 3.2

What we know:
1. MongoDB utilizes as much memory as possible to give a better performance
2. When memory utilization reaches a certain threshold percentage, MongoDB frees up the memory it holds
3. We are not able to see the memory utilization of MongoDB service in Task Manager

Is there a way to configure/increase the memory limit(100MB) on the pipeline? What if I have a lot of RAM that can be used by MongoDB?
