Flyway provides framework which will execute migrations based on directory
/data/migration
My application supports Oracle, SQLServer or MySQL, i would like to keep scripts as /data/migration/oracle and /data/migration/sqlserver etc...
Application can be deployed either on Oracle, SQLServer or MySQL. How to inform Flyway framework to use specific database deployment migrations using spring integration?
You will pass different location for each database. You may have placeholder for that. I have it done in maven plugin ond only what is needed to be changed is
<locations>
<location>db/${database.type}</location>
</locations>

I have two Spring boot applications that don't know about Liquidbase migrations since migrations are stored in a separate repository and applied by Jenkins.
I want to introduce Testcontainers testing to test communication with DB.
The issue is that I cannot store these migrations locally in the services to avoid duplication.
Is there any way to pull migrations before TestContainer start? Maybe some workaround?
As a workaround, I decided to use JGit SDK to download migrations.
More information about JGit here:

I have a spring boot application which is using Postgresql and also maven. It uses the Flyway migration to migrate database changes. I want to have a specific SQL file and run it by a command to insert some records for configuration whenever I want.
Could you please help me to handle this?
The specific topic is detailed here Spring Database Initialization.
Basically set the initialization values as you require:
spring.datasource.platform=postgres
spring.jpa.hibernate.ddl-auto=update
spring.datasource.initialization-mode=always
....
E.g. (there are much more options) if you place into resources the file data.sql it will be executed and you can add your fixtures.
For specific Flyway migrations you should check Execute Flyway Database Migrations on Startup.
Basically you add every new migration version script and it will be checked for every deployment.
I try to use flyway to manage database schema in OceanBase, but failed.
The version I used
Flyway compile("org.flywaydb:flyway-core:5.2.1")
MySQL driver runtime 'mysql:mysql-connector-java:5.1.41'
Is there anyway to use database schema management in OceanBase?
I'm not sure if oceanbase supports flyway. If you are trying to perform migration, try using OMS(Oceanbase migration service) instead, or you are trying to manage the database itself, try using ODC(Oceanbase developer center). Both are GUI tools to manage oceanbase databases. You can find more details on official website of Oceanbase.
When we write an application, we also write migrations for database schema and data, we use liquibase for that.
For example I am deploying an application locally as developer on my machine, application uses elasticsearch, but before adding some data I need to execute some query/mappings.
So, I want to add that query/mappings to some files, so, when another developer will deploy application on his machine, that query will be executed automatically.
What tools/library are using for migrations ElasticSearch schema?
I created a long time ago a project I'm still maintaining which creates an index with all settings and mappings if it does not exist at startup.
elasticsearch-beyonder is available at https://github.com/dadoonet/elasticsearch-beyonder.
For now, it works only with a TransportClient but I'm planning to add support for the Java REST Client as well.
We can deploy a web application in java container using a war. But how schema creation is handled with deployment?
Is there a way to include schema and tables creation statements with war? Or do we have to create schema with required tables manually?
How database setup is normally handled with war deployment in a java container like tomcat?
Usually during development any action with DB is performed by your ORM(ex. Hibernate). But in production mode it's not applicable and you should use some additional tools.
For example in our project we are using Flyway.
