Presto assets app
The Presto assets app crawls Presto catalogs, schemas, tables, views, and columns
and publishes them to Atlan. Build it with the AtlanPresto builder.
Creating an app creates a new connection
Each create mints a new connection and new assets. To re-crawl, re-run the existing workflow (see Re-run an existing app).
Basic authentication
- Python
Presto crawling with basic auth
from pyatlan.client.atlan import AtlanClient
from pyatlan.model.apps import AtlanPresto
client = AtlanClient()
response = (
AtlanPresto(client)
.basic( # (1)
username="atlan_user", # (2)
password="••••••", # (3)
host="presto.example.com", # (4)
)
.connection(
name="production-presto",
admin_roles=[client.role_cache.get_id_for_name("$admin")],
)
.include_metadata({"my_catalog": ["public"]}) # (5)
.run(name="presto-prod")
)
print(response.slug, response.run_id)

.exclude_metadata({"my_catalog": ["staging"]}) # (2)
.run(name="presto-prod")
