Seems like when you were uploading the dataset the runtime got interrupted which led to the corruption of the data you were trying to upload. Using force=True while deleting should allow you to delete it.

For more information feel free to check out the Hub API basics docs for details on how to delete datasets in Hub.

If you stop uploading a Hub dataset midway through your dataset will be only partially uploaded to Hub. So, you will need to restart the upload. If you would like to re-create the dataset, you can use the overwrite = True flag in hub.empty(overwrite = True). If you are making updates to an existing dataset, you should use version control to checkpoint the states that are in good shape.

Here is a solution that works exploiting $lookup on the same collection (think "self-JOIN"):

In PgAdmin open part Login/Group roles. Right click and in opened window enter new user, set permission and defined password. After refresh you will see e.g. Alice in Login/Group roles. After that open database with logged user. Click on something like mondial/postgres@PostgresSQL (db/user@server) and choose new connection. Chose which db wish to use and user wich will be connected on db.

After that you will have mondial/Alice@PostgresSQL

The problem consist from creating connection in separate file (must be create in App).

Currently GROUP BY does not not yet use the index.

This is currently being worked on. I would revisit sometime towards the end of the year to verify it is supported.

If you look into documentation for Gocql package, then you will see that the decimal is mapped to the Go's infDec data type (see its doc) so you need to use it instead of Float64.

You can also "copy on database level" from within ABAP SQL using a combined INSERT and SELECT:

You cannot use H2 2.0.202 with Hibernate ORM 5.6, because H2Dialect in Hibernate ORM produces invalid SQL for H2, H2 2.x is more restrictive and doesn't accept it by default.

H2 2.0.204 and later versions (current version is 2.1.210) have a LEGACY compatibility mode, it can be enabled by appending ;MODE=LEGACY to JDBC URL. This mode provides some limited compatibility with old versions of H2.

This trick shouldn't be required for Hibernate ORM 6.0 when it will be released.

Edited

Changes for H2 2.x.y were backported to Hibernate ORM 5.6.5.

I think it depends on how you want to access the data. If you're wanting to stream and push notifications, I would stick with Firebase. If you just need to get and post data, focus more on api implementation. With a solid rest api, you can change up your database/backend all you want and just have to update the api, not your app.

I, personally, suggest searching around for data modeling techniques in Firebase. Check out the Fireship channel on youtube. In his channel's videos, search for modeling and you'll find a ton of info on Firebase data modeling. Many will reference Angular, but the techniques are the same.
