Configuration override

Data Source configurations are set in the Data / Data Sources panel of the Domino UI. You can update it there for any permanent change. Some configuration attributes can be overridden locally in the API. A sample of Data Source type configuration is described in the Classes section below.

Usage

You can create a configuration override with any of the config classes and update your Data Source entity:

Python
R

from domino.data_sources import DataSourceClient, SnowflakeConfig

snowflake = DataSourceClient().get_datasource("snowflake-prod")

# Build a override config with a different warehouse than configured in Domino
config_xxl = SnowflakeConfig(warehouse="compute-xxl")

# Local update with no permanent change
snowflake.update(config=config_xxl)
res = snowflake.query("SELECT COUNT(*) FROM very_large_table")

# Override can also be used for temporary credentials
snowflake.update(config=SnowflakeConfig(username="admin", password="<password>"))
res = snowflake.query("SELECT secret_data FROM secret_table LIMIT 10")

library(DominoDataR)
client <- DominoDataR::datasource_client()

# Query with a different warehouse than configured in Domino
table <- DominoDataR::query(
  client,
  "snowflake-prod",
  "SELECT COUNT(*) FROM very_large_table",
  DominoDataR::add_override(warehouse = "compute-xxl")
)

# Query with temporary credentials
table <- DominoDataR::query(
  client,
  "snowflake-prod",
  "SELECT secret_data FROM secret_table LIMIT 10",
  DominoDataR::add_override(username = "admin", password="<password>")
)

To remove the configuration override, simply reset it:

from domino.data_sources import DataSourceClient, SnowflakeConfig

snowflake = DataSourceClient().get_datasource("snowflake-prod")
# Update to dev database
snowflake.update(SnowflakeConfig(database="dev"))

# Reset to default values
snowflake.reset_config()
res = snowflake.query("SELECT * FROM prod_table")

Relational Data Sources support an optional datetime precision field, which is overridable in the Data API for version 6.3.0 and above. Adjusting the precision prevents extreme datetimes from overflowing. The precision can be set to “seconds”, “milliseconds”, “microseconds”, or “nanoseconds”, with “nanoseconds” as the default.

Python
R

from domino.data_sources import DataSourceClient, SnowflakeConfig

snowflake = DataSourceClient().get_datasource("snowflake-prod")

# Update to datetime precision to milliseconds to support extremely large datetime values
snowflake.update(SnowflakeConfig(datetime_precision="milliseconds"))

res = snowflake.query("SELECT * FROM prod_table")

library(DominoDataR)
client <- DominoDataR::datasource_client()

# Query with a different datetime precision than the default
table <- DominoDataR::query(
  client,
  "snowflake-prod",
  "SELECT * FROM prod_table",
  DominoDataR::add_override(datetime_precision = "milliseconds")
)
