How to keep redis in synchronization with mongo db


i m new to mongo db i am doing a poc for mongo db with redis is there a in built in way that i can do sync between mongo and redis

MongoDB does not have a built-in way to sync with Redis, however there are a number of ways to accomplish this. You could write your own service/application that does this, use Kafka as an intermediate layer and configure both the Redis and MongoDB Connectors, or use third party ETL tools.
