db-migrate-cassandra

library0.0.5jsnpmunverified

A plugin for db-migrate that enables Cassandra database migrations using the cassandra-driver. Version 0.0.5 is the latest release. It supports common migration operations such as create/drop table, add/remove/rename column, and change column type. The package is intended to be used alongside db-migrate and currently has limited functionality (e.g., no keyspace creation). It is a niche tool for Node.js projects needing schema migrations for Cassandra.

default

✓ // No default import; used as a plugin with db-migrate

This package is a plugin for db-migrate and is not imported directly. It is loaded via db-migrate configuration.

Shows installation, configuration, and a sample migration to create a users table with primary key.

// 1. Install dependencies // npm install db-migrate db-migrate-cassandra // 2. Configure database.json // { // "cassandra": { // "driver": "cassandra", // "host": "localhost", // "port": 9042, // "keyspace": "mykeyspace" // } // } // 3. Create a migration file (e.g., 001-create-users.js) 'use strict'; exports.up = function (db, callback) { db.createTable('users', { 'name': 'varchar', 'age': 'int' }, { 'primary_key': 'name' }, callback); }; exports.down = function (db, callback) { db.dropTable('users', callback); }; // 4. Run migration from command line // npx db-migrate up --config database.json

Debug

Known issues

gotchaCassandra keyspace must exist before running migrations; no keyspace creation support.

fix

Create the keyspace manually via cqlsh or another tool before running migrations.

affects: >=0.0.0

gotchaMigration operations are limited compared to other databases; changeColumn and other DDL might not work as expected on all Cassandra versions.

fix

Test migrations thoroughly on your Cassandra cluster.

affects: >=0.0.0

gotchaThe package uses cassandra-driver under the hood; ensure the driver version is compatible.

fix

Check the cassandra-driver documentation for compatibility with your Cassandra version.

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module 'db-migrate-cassandra'

Missing installation or incorrect configuration in database.json

fix

Run 'npm install db-migrate-cassandra' and ensure the driver field in database.json is set to 'cassandra'.

All host(s) tried for query failed

Cassandra server not running or incorrect host/port configuration

fix

Verify Cassandra is running and accessible at the configured host and port.

Keyspace 'mykeyspace' does not exist

Keyspace has not been created in Cassandra

fix

Create the keyspace manually: CREATE KEYSPACE mykeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};
