Database Support for Pact Broker - maven

We are planning to implement customize Pact Broker and implement it as our own application in our workplace rather using any existing docker image.
I know Pact Broker is recommended to use with PostgreSQL and also supports MySQL, but just wanted to understand does Pact Broker supports Oracle DB also as one of its storage source ? And if yes, Could you point me in the right direction ?

No sorry, it only supports Postgres and MySQL.

Export data from Kafka to Oracle

I am trying to export data from Kafka to Oracle db. I've searched related questions and web but could not understand that we need a platform (confluent etc.. ) or not. I'd been read the link below but it's not clear enough.
https://docs.confluent.io/3.2.2/connect/connect-jdbc/docs/sink_connector.html
So, what we actually need to export data without 3rd party platform? Thanks in advance.
It's not clear what you mean by "third-party" here
What you linked to is Kafka Connect, which is Apache 2.0 Licensed and open source.
Kafka Connect is a plugin ecosystem, you install connectors individually, written by anyone, or write your own, just like any other Java dependency (i.e. a third-party)
The JDBC connector just happens to be maintained by Confluent. and you can configure the Confluent Hub CLI
to install within any Kafka Connect distribution (or use Kafka Connect Docker images from Confluent)
Alternatively, you use Apache Spark, Flink, Nifi, and many other Kafka Consumer libraries to read data and then start an Oracle transaction per record batch
Or you can explore non-JVM kafka libraries as well and use a language you're more familiar with doing Oracle operations with

How to upload Spring Boot application using RabbitMQ messaging to AWS EC2?

I have a functioning application using Spring Boot, Rabbit MQ & MySQL DB locally. I'm curious, how I can upload this app to the AWS Environment and get it working seamlessly.
The only part where I'm lost is how to get RabbitMQ in the cloud? Any suggestions?
I see three options for your needs :
Use AmazonMQ managed service. This uses ActiveMQ under the hood, and supports the AMQP protocol (so you can continue to use the RabbitMQ client). Here's an article on how to do it : https://aws.amazon.com/blogs/compute/migrating-from-rabbitmq-to-amazon-mq/.
Use a third-party managed service (such as CloudAMQP). This is similar to the first option, but you can choose a RabbitMQ provider if you wish.
Install RabbitMQ on an EC2 instance and manage it yourself. This is the most flexible option, but it will require more effort on your part and it will probably cost more. I would recommend this option only if you have special requirements that are not met by using a hosted service.
In all cases, I would also recommend to use a messaging library such as Spring Messaging or Apache Camel to isolate your code from your messaging implementation. This will reduce the boilerplate code you need for messaging and allows you to focus on your application logic.

How to implement kafka-connect using apache-kaka instead of confluent

I would like to use an open source version of kafka-connect instead of the confluent one as it appears that confluent cli is not for production and only for dev. I would like to be able to listen to changes on mysql database on aws ec2. Can someone point me in the right direction.
Kafka Connect is part of Apache Kafka. Period. If you want to use Kafka Connect you can do so with any modern distribution of Apache Kafka.
You then need a connector plugin to use with Kafka Connect, specific to your source technology. For integrating with a database there are various considerations, and available for MySQL you specifically have:
Kafka Connect JDBC - see it in action here
Debezium - see it in action here
The Confluent CLI is just a tool for helping manage and deploy Confluent Platform on developer machines. Confluent Platform itself is widely used in production.

Apache Kafka Connect With Springboot

I'm trying to find examples of kafka connect with springboot. It looks like there is no spring boot integration for kafka connect. Can some one point me in the right direction to be able to listen to changes on mysql db?
Kafka Connect doesn't really need Spring Boot because there is nothing for you to code for it, and it really works best when ran in distributed mode, as a cluster, not embedded within other (single-instance) applications. I suppose if you did want to do it, then you could copy relevent portions of the source code, but that of course isn't using Spring Boot, and you'd have to wire it all yourself
The framework itself consists of a few core Java dependencies that have already been written (Debezium or Confluent JDBC Connector, for your mysql example), and two config files. One for Kafka Connect to know the bootstrap servers, serializers, etc. and another for the actual MySQL connector. So, if you want to use Kafka Connect, run it by itself, then just write the consumer in the Spring app.
The alternatives to Kafka Connect itself would be to use Apache Camel within a Spring application (Spring Integration) or Spring Cloud Dataflow and interfacing with those Kafka "components" (which aren't using the Connect API, AFAIK)
Another option, specific for listening to MySQL, is to use Debezium Engine within your code.

How Can I Configure ActiveMQ In Geronimo To Use MySQL Persistence?

I was able to configure this quite easily in TomEE, but have not been able to find a reference that describes how to configure the resource adapter to use mysql instead of the default. Can anyone help?
look on http://tomee.apache.org/jms-resources-and-mdb-container.html (part Internal ActiveMQ Broker with JDBC Persistence)
