here’s a general guide on how to proceed:
- Set Up Your Development Environment
Prerequisites:
Git: To clone the MongoDB repository.
SCons: The build system used by MongoDB.
C++ Compiler: MongoDB is primarily written in C++, so you’ll need a compatible compiler (e.g., GCC for Linux, MSVC for Windows).
Install SCons:
pip install scons
Install necessary build tools:
For Ubuntu/Debian:
sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install python3-pip
For CentOS/RHEL:
sudo yum groupinstall ‘Development Tools’
sudo yum install python3-pip
2. Clone the MongoDB Repository
Navigate to the directory where you want to clone the repository, then run:
git clone GitHub - mongodb/mongo: The MongoDB Database
cd mongo
3. Modify the Source Code
Find the source code for the insert operation. The code related to the insert operation is generally located in:
src/mongo/db/ops/insert.cpp: This file contains the implementation for the insert operation.
Make your changes here. Ensure you understand the code well to avoid introducing errors.

Build MongoDB
Before building, it’s good to check out the branch or tag you need. For example:
git checkout
To build MongoDB, use SCons:
scons
If you need a specific build configuration, you can pass arguments to SCons. For example:
scons all
This builds all components of MongoDB. -
Test Your Changes
Run MongoDB with your modifications to ensure everything works as expected. You might want to run existing tests or write new ones. -
Debugging
If you encounter issues, you might need to debug your changes. You can use tools like gdb (GNU Debugger) for this purpose. -
