MongoDb aggregation 16MB buffer size limit

Question

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.

Comments

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.
