dbcp

dbcp

Dump MySQL, PostgreSQL, and SQLServer databases directly to local (comrpessed) JSON, Amazon Web Services (AWS) S3, Google Cloud Storage (GCS), or another database.

Either --sourceType or --sourceFile and --targetType or --targetFile are required. Other options can be shortened, e.g --user instead of --sourceUser. Unless a database-to-database requires both --sourceUser and --targetUser are required.

dbcp pipes Readable Node.JS streams to Writable streams. No intermediate storage is required.

Example

Setup

$ npm init
$ npm install dbcp

Dump SQLServer table to gzipped JSON file

$ ./node_modules/.bin/dbcp \
  --sourceType mssql --host localhost --dbname mymsdb --port 1433 \
  --user SA --password "MyP@ssw0rd#" \
  --table foobar --targetFile file.json.gz

Dump PostgreSQL table to Google Cloud Storage gzipped JSON file

$ ./node_modules/.bin/dbcp \
  --sourceType postgresql --host localhost --dbname postgres --port 5433 \
  --user postgres --password postgres \
  --table foobar --targetFile gs://bucket/file.json.gz

Dump MySQL table to Amazon Web Services S3 gzipped JSON file

$ ./node_modules/.bin/dbcp \
  --sourceType mysql --host localhost --dbname mydb --port 8083 \
  --user root --password wp \
  --table foobar --targetFile s3://bucket/object.json.gz
