I have moved my MySQL database to RDS.
I would like to update the connector that publishes messages from an outbox table to a specific Kafka topic to point to the RDS instance.
What would be the steps I would have to take to not resend the messages and just continue from the point at which the connector was for the previous instance?

I am setting up a connection between MySQL Workbench and Amazon AWS RDS MySQL database. How can I sync the two databases?
The operation (Inserting, deleting and updating) directly happens to cloud (AWS RDS) database instead of storing first on the local database which is further sync to cloud. Because it is taking much time in storing procedure directly to the cloud.
I expect all operations happen first in a local database which then syncs to the cloud database.
You may be interested in using the AWS Database Migration Service, which should be able to meet all of your requirements including remote replication of your local database. (https://aws.amazon.com/dms/)
I am trying to connect Kafka connector with database using confluent kafka jdbc connector.
I can do insert and update the records from one database to another, but when I try to delete the records, the deleted records are not reflecting into target db. I mean synchronization of records(deleted records) are not deleted from target database.
You won't be able to until this gets merged

I am new to Amazon RDS, and looking to get answer for my question below and couldn't find the answer on stackoverflow yet.
I have a MySQL Database on premise that I want to synchronize with the MySQL Database on Amazon RDS. I understand that replication is possible with Amazon RDS, but how about continuous synchronization? Say my existing local database has one transaction that has been made, I want to synchronize just that transaction, either immediately or by schedule, so that I don't need to replicate the whole thing to RDS.
Does RDS have this feature for MySQL or any other database?
If not, what tools should I be using? EC2 + ? ?
Or is there any database that supports this so I can just run the database on EC2?
Your best (first) option should probably be the AWS Database Migration Service. This is a migration service for exactly your use-case.
If uptime is less of an issue, you could always do a mysql_dump, move that to an EC2 instance and load that into an RDS instance.
I have a ruby on rails run on amazon ec2, database is mySQL.
Now I want to use Amazon RDS to backup this database in case the ec2 fails.
I read through the Amazon RDS user guide,it tells how to create a DB instance.
My question is:
1.what is the relation between created DB instance and my ec2 database?
2.When the DB instance "connect" to my ec2, what will happen?
The data used to send to ec2 mySQL server will be send to DB instance?
Is the database totally shifted to DB instance?So before I connect I should creare a same database in DB instance and tell ec2 send data to RDS ever since
3.If not,how the DB instance know the ec2 is down and takeover the data?
EDIT:
(Unsure)Is it that DB instance is just a place to put database.In order to use it,I need to set up database in DB instance,then connect to it by modifying database.yml file(this file tell rails server where the stored data goes).
How Is it possible to tell when the local database stops then at that time switch to DB instance?
There is absolutely no relationship between your EC2 MySQL DB and the RDS DB Instance. So what you are asking for is just not possible.
A better approach I would say is to have only RDS (No need to have MySQL running locally on EC2 instance). RDS takes snapshots regularly. Also, RDS is a managed service, so most of the MySQL administration tasks are handled by AWS and you don't have to worry. And you can rely on RDS snapshots from Backup perspective.
I have a MySQL instance running on RDS and I have created a snapshot and I read I can connect to snapshot. But I can't find snapshot specific hostname there on RDS management console. Can I really connect to AWS RDS snapshot using mysql client like I connect to instances?
There was an implication in the linked answer that you would need to restore the snapshot to an RDS instance. A snapshot isn't a live MySQL database -- you can't connect to it and use that state until you restore a new RDS instance from that snapshot. Here's how snapshots are defined in the documentation, if it helps:
DB snapshots are user-initiated and enable you to back up your DB
instance in a known state as frequently as you wish, and then restore
to that specific state at any time. DB snapshots can be created with
the Amazon RDS console or the CreateDBSnapshot action in the Amazon
RDS API. DB snapshots are kept until you explicitly delete them with
the Amazon RDS console or the DeleteDBSnapshot action in the Amazon
RDS API.
You can restore from a snapshot from the AWS console, or programmatically through the:
CLI: restore-db-instance-from-db-snapshot
API: RestoreDBInstanceFromDBSnapshot
