Learn Java Database Migrations, Flyway, Liquibase

Kaufman Skill Map

Kaufman skill map untuk menguasai database migration sebagai engineering skill: deconstruction, learning loop, deliberate practice, invariant, dan production-grade mastery target.

Database Evolution Mental Model

Mental model evolusi database sebagai state, history, intent, dan evidence; membahas schema sebagai contract, migration sebagai state transition, drift, compatibility, dan failure reasoning.

Migration Taxonomy

Taxonomy database migration untuk engineer Java: SQL-first, changelog-driven, ORM auto-DDL, schema diff, forward-only, rollback-capable, data migration, reference data, drift reconciliation, dan decision model.

Migration Lifecycle

Lifecycle migration database production-grade: authoring, review, validation, dry run, environment promotion, deployment, observation, failed migration recovery, repair, dan audit closure.

Versioning, Ordering, and History

Versioning, ordering, history table, checksum, drift, branch conflict, dan aturan immutable migration untuk sistem Java production.

Idempotency and Repeatability

Idempotency, repeatability, determinism, rerunnable migration, Flyway repeatable migration, Liquibase runOnChange/runAlways, dan batas aman script yang bisa dijalankan ulang.

Transaction Boundaries and DDL Semantics

Transaction boundaries dan DDL semantics untuk database migration production-grade: transactional DDL, implicit commit, lock, autocommit, online DDL, Flyway/Liquibase transaction knobs, dan failure modelling.

Expand/Contract Pattern

Expand/contract pattern untuk zero-downtime schema evolution di sistem Java production: compatibility window, additive change, dual-read/write, backfill, cutover, contract, verification, dan anti-pattern.

Flyway Core Model

Deep dive mental model Flyway: versioned migration, repeatable migration, baseline, schema history table, checksum, callbacks, placeholders, Java migration, lifecycle command, dan operational invariants.

Flyway Project Structure

Struktur project Flyway untuk Java, Maven, Gradle, Spring Boot, multi-module repository, modular monolith, microservices, multi-schema, multi-tenant, naming convention, ownership, dan CI/CD artifact design.

Flyway Versioning Strategy

Strategi versioning Flyway untuk tim Java production-grade: numbering, timestamp, release train, branching, merge conflict, hotfix, out-of-order, baseline, repeatable migration, CI guardrails, dan audit mapping.

Flyway Validate, Repair, Baseline, Clean

Pendalaman Flyway validate, repair, baseline, baselineOnMigrate, clean, schema history recovery, checksum mismatch, failed migration, missing migration, guardrail production, dan operational playbook.

Flyway Repeatable Migrations

Flyway repeatable migrations untuk view, function, procedure, reference data, dan replaceable database object dengan mental model checksum, ordering, determinism, dan production guardrails.

Flyway Callbacks, Placeholders, and Environments

Flyway callbacks, placeholders, dan environment-specific configuration sebagai mekanisme lifecycle hook dan parameterisasi yang aman untuk database migration production-grade.

Liquibase Rollback Model

Liquibase rollback model secara realistis: automatic rollback, custom rollback, tag, rollback SQL, rollback test, roll-forward, dan production decision framework.

Liquibase Diff, Snapshot, and Drift Detection

Liquibase diff, snapshot, generate-changelog, diff-changelog, dan drift detection sebagai kontrol engineering untuk menjaga database tetap sinkron dengan changelog.

Liquibase Java API and Spring Boot Integration

Liquibase Java API dan Spring Boot integration untuk menjalankan migration secara aman, observable, dan terkendali di aplikasi Java production-grade.

Safe DDL Patterns

Safe DDL patterns untuk column, table, constraint, index, foreign key, enum, rename, dan destructive schema change di database production.

Data Migration Patterns

Data migration patterns untuk backfill, batching, chunking, resumability, verification, dual-write, checkpoint, dan Java-based migration di production.

Large Table Migration

Large table migration untuk tabel raksasa, lock modelling, index build, online DDL, copy-and-swap, shadow table, replication, throttling, dan cutover.
