This command sync and download the fresh copy of the master package. Install Ruby if you don't already have it on your machine. First, you can update your Manjaro system using the following command: sudo pacman. If you have a relatively simple database it might work great! For serious production use, use the database’s tools to copy databases for the same database type, and for different database types, use the Sequel API. It is best designed for quick conversions and testing. Also, the data type conversion may not be exactly what you want. It doesn’t handle database views, functions, triggers, schemas, partial indexes, functional indexes, and many other things. Note that the support for copying is fairly limited. This copies the table structure, table data, indexes, and foreign keys from the MySQL database to the PostgreSQL database. That said it has limits! This is directly from the documentation: Written in full, the connection parameters will be either of these options: psql -h myhost -p 5432 -d mydb -U myuser. This assumes that all your connection parameters are defaults, which may not be true. This method should help when transferring between ADO, Amalgalite, IBM_DB, JDBC, MySQL, Mysql2, ODBC, Oracle, PostgreSQL, SQLAnywhere, and TinyTDS to SQLite3. From here on, we will assume that the psql command is enough to allow you access to the PostgreSQL server. There is really no very easy way to do this since the data types between the databases are different.īut here is one way that has worked for me in the past and might work for you! The Ruby Sequel project comes with a command line tool for copying databases. Make sure to back up your data and be vigilant, because this kind of thing is fraught at best. Transferring Data From Postgres/MySQL to SQLite3 This section is something to give you a starting point on how to get from X to SQLite. We recommend at least skimming this before putting it into production. The ecto_sqlite3 documentation includes a good guide on the limits of using Ecto with SQLite3. This guide is heavily influenced by the guide from Phoenix Core Team Member, Michael Crumm.įollowing are the steps required to make this work: Create Volumeĭefmodule Name. Volumes are limited to one host, this currently means that fly.io hosted Elixir applications that use SQLite3 for their database can't be deployed to multiple regions.īut if you are okay using beta software, LiteFS could work for multi-region sync, check it out! But this guide is going to assume you have one node and one volume. To make this work, you will need to place your databases on persistent Volumes as your deployment image will get overwritten the next time you deploy. This guide will assume you have setup and configured Phoenix Application using ecto_sqlite3 running locally. While Elixir applications on Fly.io normally run on Postgres databases, you can choose to run them on SQLite3.
