I need two scripts (Technology you can choose python/shell script - Bash/zsc/csh) who can do following work and postgres function to extract from database based on certain condition.
1. Load data from Multiple mongoDB to postgres
2. Load data from multiple postgres DB to one postgres DB.
It's basically two loader scripts are required.
Non-functional requirements are
1. Both the DBs are having multi-million records
2. The loader script should run on Ubuntu servers with scheduled time for loading
