Superset / Preset connect to Honeydew via JDBC connection, using the Trino protocol.

​
Metadata Sync

With Metadata Sync, Honeydew can synchronize metadata such as field descriptions to Superset or Preset.
Metadata Sync for Preset is in Preview. Reach out to support@honeydew.ai to enable.

​
Passing Parameters

Parameters can be passed to the Honeydew SQL interface via the FROM statement. Preset and Superset can parameterize queries using Jinja. To pass a URL parameter from Superset/Preset, create a Virtual Dataset (with a custom SQL) that looks as following: 
-- pass URL parameter param1 from Preset to a Honeydew parameter
select *, '{{ url_param('param1') }}' as "$param1"
from domains.analytics
To pass an SQL Lab template parameter, build SQL that looks like: 
-- pass template parameter $param1 from Preset to a Honeydew parameter
select *, '{{ param1 }}' as "$param1"
from domains.analytics

Setting up a New Database connection

Superset/Preset database connections are mapped to a Honeydew workspace and branch
It is recommended to use an API Key for setting up the connection.
  1. Create a new database
  2. Choose Trino from the list of supported databases
  3. Set a unique Display Name for the connection (e.g. “Honeydew”)
  4. Enter the following URI as the input:
trino://<api key>:<api secret>@jdbc.honeydew.cloud:443/<workspace>__<branch>
Where <api key> is the generated API key, and <api secret> is the corresponding API secret. Or alternatively: 
trino://<user>:<password>@jdbc.honeydew.cloud:443/<workspace>__<branch>
Where <user> is a Honeydew username, and <password> is that user’s password.
API key and API secret (or alternatively, user and password) must be url-encoded., i.e. user@domain.com is user%40domain.com. Encoding can be done using python (from urllib.parse import quote_plus), or via any urlencode website.
If your organization uses a custom hostname for the JDBC connection, you can locate it in the Honeydew UI, under the JDBC section in Settings.
For example, for user user@domain.com, password 123456 and workspace tpch (prod branch) the URI would be: 
trino://user%40domain.com:123456@jdbc.honeydew.cloud:443/tpch
And for dev branch: 
trino://user%40domain.com:123456@jdbc.honeydew.cloud:443/tpch__dev
  1. Click Test Connection to verify the connection settings
  2. Create the database connection

​
Creating a new dataset

A dataset in Superset/Preset is mapped to a specific database connection, and a specific domain.
  1. Create a new dataset
  2. Choose the previously created database connection (it will be of type trino)
  3. For SCHEMA, choose world if you would like to connect to all metadata in Honeydew, or domains if you would like to connect to a specific domain
  4. For TABLE, choose world if you have chosen the world schema, or choose the relevant domain, if you have chosen the domains schema
  5. Create the dataset
  6. You can now create charts and dashboards using this dataset
