Configuration

The datasource definition for this driver requires the following information:

{
  "type" : "snowflake",
  "host" : "HIYSSHM-TEAM_GRAPH_INTELLIGENCE_ENGINE.snowflakecomputing.com",
  "database" : "MOVIES",
  "schema" : "V2",
  "warehouse" : "DEFAULT_WAREHOUSE",
  "role" : "movie_admin"
}

Virtual Graph works with a private-key based secret with that configuration.

Limiting the number of fetched rows

Judging from the JDBC driver source code, JDBC fetch size might be supported. However, the Snowflake documentation recommends using the following for restricting either memory pressure or fetch size:

These can be configured under the same names inside additionalProperties.
