Send processed data from Unstructured to Snowflake.

The requirements are as follows.

• A Snowflake account and its account identifier.

  To get the identifier for the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click your username, and then click Account > View account details.
  3. On the Account tab, note the value of the Account Identifier field.

  Alternatively, the following Snowflake query returns the current account’s identifier:

  Copy

  Ask AI

  SELECT CURRENT_ORGANIZATION_NAME() || '-' || CURRENT_ACCOUNT_NAME() AS "Account Identifier"
  

• The Snowflake user’s login name (not its username) and its password in the account.

  To view the login name for a user:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Admin > Users & Roles.
  3. On the Users tab, in the list of available users, click the name of the target user.
  4. In the About tile, note the Login Name for the user.

  Alternatively, the following Snowflake query returns information about the user with the username of <my-user>, including their login_name value representing their login name:

  Copy

  Ask AI

  SHOW USERS LIKE '<my-user>';
  

• The name of the Snowflake role that the user belongs to and that also has sufficient access to the Snowflake database, schema, table, and host.

  • To create a database in Snowflake, the role needs to be granted CREATE DATABASE privilege at the current account level; and USAGE privilege on the warehouse that is used to create the database.
  • To create a schema in a database in Snowflake, the role needs to be granted USAGE privilege on the database and the warehouse that is used to create the schema; and CREATE SCHEMA on the database.
  • To create a table in a schema in Snowflake, the role needs to be granted USAGE privilege on the database and schema and the warehouse that is used to create the table; and CREATE TABLE on the schema.
  • To write to a table in Snowflake, the role needs to be granted USAGE privilege on the database and schema and the warehouse that is used to write to the table; and INSERT on the table.
  • To read from a table in Snowflake, the role needs to be granted USAGE privilege on the database and schema and the warehouse that is used to write to the table; and SELECT on the table.

  To view a list of available roles in the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Admin > Users & Roles.
  3. Click the Roles tab.

  Alternatively, the following Snowflake query returns a list of available roles in the current account:

  Copy

  Ask AI

  SHOW ROLES;

• The Snowflake warehouse’s hostname and its port number in the account.

  To view a list of available warehouses in the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Admin > Warehouses. This view does not provide access to the warehouses’ hostnames or port numbers. To get this information, you must run a Snowflake query.

  The following Snowflake query returns a list of available warehouse types, hostnames, and port numbers in the current account. Look for the row with a type of SNOWFLAKE_DEPLOYMENT:

  Copy

  Ask AI

  SELECT t.VALUE:type::VARCHAR as type,
         t.VALUE:host::VARCHAR as host,
         t.VALUE:port as port
  FROM TABLE(FLATTEN(input => PARSE_JSON(SYSTEM$ALLOWLIST()))) AS t;
  

• The name of the Snowflake database in the account.

  To view a list of available databases in the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Data > Databases.

  Alternatively, the following Snowflake query returns a list of available databases in the current account:

  Copy

  Ask AI

  SHOW DATABASES;
  

• The name of the schema in the database.

  To view a list of available schemas for a database in the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Data > Databases.
  3. Expand the name of the target database.

  Alternatively, the following Snowflake query returns a list of available schemas in the current account:

  Copy

  Ask AI

  SHOW SCHEMAS;
  

  The following Snowflake query returns a list of available schemas for the database named <database_name> in the current account:

  Copy

  Ask AI

  SHOW SCHEMAS IN DATABASE <database_name>;
  

• The name of the table in the schema.

  To view a list of available tables for a schema in a database in the current Snowflake account:

  1. Log in to Snowsight with your Snowflake account.
  2. In Snowsight, on the navigation menu, click Data > Databases.
  3. Expand the name of the database that contains the target schema.
  4. Expand the name of the target schema.
  5. Expand Tables.

  Alternatively, the following Snowflake query returns a list of available tables for the schema named <schema_name> in the datbase named <database_name> in the current account:

  Copy

  Ask AI

  SHOW TABLES IN SCHEMA <database_name>.<schema_name>;
  

  Snowflake requires the target table to have a defined schema before Unstructured can write to the table. The recommended table schema for Unstructured is as follows. In the following CREATE TABLE statement, replace the following placeholders with the appropriate values:

  • <database_name>: The name of the target database in the Snowflake account.
  • <schema_name>: The name of the target schema in the database.
  • <number-of-dimensions>: The number of dimensions for any embeddings that you plan to use. This value must match the number of dimensions for any embeddings that are
    specified in your related Unstructured workflows or pipelines. If you plan to use Snowflake vector embedding generation or Snowflake vector search, this value must match the number of dimensions that you plan to have Snowflake generate or search against.
