MongoDB Migration

• To migrate MongoDB indexes and verify.
• To compare the db.collection.count() between the source and targtet database.

Environment

• Python >= 3.4
• pymongo >=3.6

Structuring

• Class Mongo to call pymongo to operate database
• Class Handler to do count_diff / index_migrate / index_diff

How to start ?

• Add a connections.py file and export your source and target uri as well as database name.

example:

source_client = "mongodb://12.23.24.25:27017/test_db"
target_client = "mongodb://23.44.55.111:27017/test_db"
db = "test_db"

• Call the function you want

example:

if __name__ == "__main__":
    source_uri = Constant.source_cluent
    target_uri = Constant.target_client
    db = Constant.db

    Handler(source_uri, target_uri, db).index_migrate()
    Handler(source_uri, target_uri, db).index_diff()
