Service that implements polling data from the replicated database (Aurora MySQL), writing to Dynamo DB tables.

The source database schema (Oracle) and DMS CDC grants.

The destination database schema (Aurora MySQL). Contains the following two sub-folders:

These scripts should be run sequentially on a non-integrated Aurora MySQL environment to create the tables and seed them with some sample data scenarios. Further details can be found at https://wiki.i-env.net/display/MES/TARS+Replica+-+Sample+Journal+Data

These should be run after the scripts in sample-data-load (for a non-integrated environment) or after DMS has set up and initial load completed (for a TARS integrated environment). Further details can be found at https://wiki.i-env.net/display/MES/TARS+Replica+-+Database+Objects

There are some integration tests in the solution. These spin up DynamoDB local + require MySQL in Docker to test against.

In order to run the integration tests, you need:

• A JRE (tested with Java 8)
• Docker (tested with Docker Desktop for Mac)

To run the integration tests, open a cmd window and change to the e2e directory and run

docker-compose up --build

In a separate window run:

npm run test:int

If you get issues starting the integration tests due to ports already being bound, you can kill old instances of the test components by running:

npm run stack:down

remember to run

docker-compose down

to clean up the docker container.

There are some e2e tests for the journal and users pollers. These spin up DynamoDB local + MySQL in Docker to test against.

In order to run the E2E tests, you need:

• A JRE (tested with Java 8)
• Docker (tested with Docker Desktop for Mac)
• A valid AWS credentials profile (either set as default or reference in the AWS_PROFILE envvar)

To run the E2E tests, open a cmd window and change to the e2e directory and run

docker-compose up --build

In a separate window run:

npm run e2e

If you get issues starting the E2E tests due to ports already being bound, you can kill old instances of the test components by running:

npm run stack:down

remember to run

docker-compose down

to clean up the docker container.
