Import from and export to other Databases

[amark]

If we write an import feature from other databases to GUN we might want to prioritize something like Hadoop/Hive (or DAT?) or something like that. Because people are already probably using that and Hadoop has already built the drivers/import code for them for all other existing databases.

This way we can then use Hadoop to (practically speaking) import data from every where else.

Although I honestly don't think people should bother migrating into GUN. Why? Because data is the life blood of your app, so your entire app was probably built around the database, and converting/migrating is painful. GUN is forward facing for new apps, but people might be desperate enough from the hurt of their current system that they might want to do it anyways... and it would be nice to allow them to do so in a easier manner.

Metabase looks like a cool tool to interact with existing datasources.
They currently work with: 1) H2
2) MongoDB
3) MySQL
4) Postgres

This might also be something we want to add support for.

anything update

[amark]

@wanghaisheng should be easy to do something yourself, like:

Note: pseudo-code

sql("SELECT * FROM users" , function(data){
  data.forEach(function(record){
    gun.get('users').set(record);
  });
});

But we won't be supporting database-specific import systems.

If you build one, add it to the wiki!!! I'm sure others would love this.

If you don't care about import/export, but want gun to use another database as its storage engine, check out https://github.com/sjones6/gun-flint .
