This is a simulator to showcase how replication/sharding work behind the scene. We will use Student management as base of it. Sample User Data

Stage1 | Base Work

Implementation

• Create a utility via which we can perform the CRUD operation on Student
  • Create : Student data should be stored in file as per the roll number order
  • Retrieve on the basis of roll number: File will be read line by line and then student information would be displayed
  • Update : File will be read line by and then Student record should be updated
  • Delete : File will be read line by line and then Student record should be deleted
• Student metadata
  • Name
  • Roll Number
  • Class
• Utility will take a yaml file as an input to take the detail where student information would be shared

Problem

What if I delete the file that is storing the student data how we will recover from that?
