Earlier I was using Redis DB and in that, I have 8 databases set in the Redis conf file and I have a total of 8 databases named db0, db1, db2 ....db7.
recently I have created a new instance of memoryDB in AWS and in that redis config file i have set the database's value to 16 but I'm getting only db0 database rest are missing.
Can someone help how I can create the rest of the databases like db1 db2 to the same memory DB instance?
Thank you in advance.
Amazon MemoryDB for Redis (and Amazon ElastiCache for Redis in cluster-mode-enabled configurations) support DB0 only.

I am new to AWS. I have a confusion which I want to figure out. My question is: Can we create multiple databases on a single Amazon RDS Aurora DB Instance? by simply connecting to the database engine using root credentials and querying "CREATE TABLE IF NOT EXISTS" command?
Hope I am much clear about my question. Further, Please guide if there is any other option to achive defined functionality.
TIA.
Based on the comments.
You create extra databases using SQL. Once you connect to your Aurora RDS, either MySQL or PostgreSQL, using mysql or psql clients (or other client), you can use SQL to create new databases:
MySQL: CREATE DATABASE Statement
PostgreSQL: CREATE DATABASE
I created a snapshot of my RDS Postgres DB, and I am trying to use that snapshot to create an AWS Aurora DB using the migrate snapshot option in AWS console, however the option is disabled for me, and I can't understand why?
According to this official AWS blog, I should be able to migrate my RDS postgres DB into Aurora DB using the migrate snapshot option.
I created this snapshot from a Postgres DB running on version 12.5. I have created another snapshot from another Postgres DB running on version 9.6.20, and I face the same issue there as well.
12.5 and 9.6.20 versions of PostgresSQL are not supperted by aurora. What is supported is listed here.
I want to periodically sync my Cloud SQL Postgres DB with an Amazon Aurora DB.
Setting up a Lambda that does pgdump and psql from one to the other should work but is there a cleaner solution?
You can take a look at the Database Migration Service in AWS. As long as one of the databases is in AWS (which Aurora is) you can use it to perform full-loads + continuous migration using Change Data Capture. PostgreSQL is supported, so you'd have to create a migration instance, configure the Postgres and Aurora endpoints and set up a replication task.
Reference
Creating tasks for ongoing replication using AWS DMS
I ended up running a pg_dump and psql cron job on an EC2 instance. I could not access GCP db as endpoint as from DMS for some reason.
We need to replicate data from an Amazon RDS (MySQL) databaes to an Aurora PostgreSQL database. Each database is on a different AWS account and region.
The data must be replicated in the PostgreSQL instance every 6 hours, so we need the guarantee that the data doesn't duplicate even if a field updated for a record.
Which method, tool, or design is better to do that? (Could be different to AWS.)
You could facilitate one of the following services provided by AWS:
Database Migration Service
Glue
The AWS Database Migration Service supports:
Using an Amazon-Managed MySQL-Compatible Database as a Source for AWS DMS
Using a PostgreSQL Database as a Target for AWS Database Migration Service
I have a local MySQL database and I want to migrate the data inside of it to a remote MySQL database (using RDS on AWS). How can I migrate my data between the two instances?
AWS DMS helps you migrate large, terabyte-scale databases to the AWS
Cloud easily and securely. During migration, the source database
remains fully operational, minimizing downtime.
But judging form your question you want homogeneous data migration and as per AWS Documentation:
If you're performing a homogeneous migration, use your engine’s native
tools, such as MySQL dump or MySQL replication.
Refer to this answer for using SQL Dump on larger data.
Thanks
Use AWS database migration service that is available in Aws. You need to provide your database end-point I,e your on premises data- base server end-point in it and also set your db engine parameters to your requirement and launch. it talks 10-15 minutes to migrate your data to cloud and from there you can continue accessing your database from the AWS it self.
The other method is, take a recent back up of your on premises database. Launch an instance in aws EC2 and install the db that you are using on premises.copy the back file in your system to cloud.using the backup file available launch the database.set up an RDS instance of the type that you have installed in EC2, and connect the end points.
