## List of Redis Databases ##
|
|
|
|
The databases used by CartoDB are:
|
|
|
|
- **0 - tables_metadata**: stores metadata from cartodb tables
|
|
- **3 - api_credentials**: stores the credentials to access to CartoDB via API. This credentials are OAuth validated tokens and API keys
|
|
- **5 - users_metadata**: stores metadata about the users account and database
|
|
|
|
### tables_metadata database ###
|
|
|
|
`tables_metadata` database stores metadata from the user tables. This metadata can be the privacy of the table, the owner identifier, the schema, and so on.
|
|
|
|
The database is structured in hashes. The key of each hash has the following format:
|
|
|
|
```
|
|
rails:<database_name>:<table_name>
|
|
```
|
|
|
|
The values of the hash are:
|
|
|
|
- `the_geom_type`: the geometry type. Example: `point`
|
|
- `infowindow`: the CSV string of values to use in the infowindow SQL. eg. 'id, name, description'. Should be suitable for passing to the CartoDB API
|
|
- `privacy`: the privacy of the table. 0 means **private** and 1 means **public**
|
|
- `user_id`: the identifier of the owner
|
|
|
|
### api_credentials ###
|
|
|
|
`api_credentials` database stores a list of credentials which can be used to be authenticated via the API. The database is organized in hashes. Each hash is identified by this format of key:
|
|
|
|
```
|
|
rails:oauth_tokens:<token>
|
|
```
|
|
|
|
The values of the hash are:
|
|
|
|
- `user_id`: the identifier of the user which is associated to the token
|
|
- `time`: the time which the token was created
|
|
|
|
### users_metadata ###
|
|
|
|
`users_metadata` Holds records of the username/subdomain to id and name of database so that we can easily go from their subdomain to their user database. The following keys are used:
|
|
|
|
```
|
|
rails:users:<username/subdomain>
|
|
```
|
|
|
|
The values of the hash are:
|
|
|
|
- `id`: user id on the metadata database
|
|
- `database_name`: name of the user database
|
|
- `map_key`: api key
|
|
- `mapviews`: hash with this values:
|
|
- `global`: sorted set of map views, the key for this sorted set is `%Y%m%d`
|
|
- `stat_tag:<visualization_id>`: sorted set of map views for a given visualization
|
|
- `api_calls`: array of aggregated map views for the last 30 days
|
|
- `last_active_time`: last time the user loaded their dashboard
