mix ash_scylla.migrate (AshScylla v1.0.0)

Copy Markdown View Source

Runs pending CQL migrations and applies resource schema changes.

This task:

  1. Runs any pending migration files from priv/migrations that haven't been recorded in the schema migrations tracking table
  2. Optionally runs automatic schema migration for all AshScylla resources (diffing resource definitions against snapshots)

Usage

# Run all pending migrations
mix ash_scylla.migrate

# Run migrations up to a specific version
mix ash_scylla.migrate --to 20240101120000

# Run a specific number of pending migrations
mix ash_scylla.migrate --step 3

# Dry run (show what would be executed)
mix ash_scylla.migrate --dry-run

# Use a specific repo
mix ash_scylla.migrate --repo MyApp.Repo

# Create keyspace before migrating
mix ash_scylla.migrate --create-keyspace

# Only run migration files (skip auto-schema migration)
mix ash_scylla.migrate --migrations-only

# Only run auto-schema migration (skip migration files)
mix ash_scylla.migrate --schemas-only

Options

  • --repo - The repo module to use (defaults to auto-detected repo)
  • --dry-run - Print DDL statements without executing them
  • --create-keyspace - Create the keyspace before running migrations
  • --keyspace - Override the keyspace name
