Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://help.ica.illumina.com/project/p-base/base-snowflake.md). # Snowflake ### User Every Base user has 1 snowflake username: ICA\_U\_\ ### User/Project-Bundle For each user/project-bundle combination a role is created: ICA\_UR\_\\_\\_\_\ This role receives the viewer or contributor role of the project/bundle, depending on their permissions in ICA. ## Roles Every project or bundle has a dedicated Snowflake database. For each database, 2 roles are created: * \\_\\_VIEWER * \\_\\_CONTRIBUTOR ### Project viewer role This role receives * REFERENCE and SELECT rights on the tables/views within the project's PUBLIC schema. * Grants on the viewer roles of the bundles linked to the project. ### Project contributor role This role receives the following rights on current an future objects in the project's/bundle database in the PUBLIC schema: * ownership * select, insert, update, delete, truncate and references on tables/views/materialized views * usage on sequences/functions/procedures/file formats * write, read and usage on stages * select on streams * monitor and operate on tasks It also receives grant on the viewer role of the project. ## Warehouses For each project (not bundle!) 2 warehouses are created, whose size can be changed ICA at **projects > your\_project > project settings > details**. * \\_\\_QUERY * \\_\\_LOAD
Using Load instead of Query warehouse When you generates an oauth token, ICA always uses the QUERY warehouse by default (see bold part below): *snowsql -a iap.us-east-1 -u ICA\_U\_277853 --authenticator=oauth -r ICA\_UR\_274853\_603465\_264891 -d atestbase2\_264891 -s PUBLIC **-w ATESTBASE2\_264891\_QUERY** --token=\* If you wish to use the LOAD warehouse in a session, you have 2 options : 1. Change the name in the connect string : *`snowsql -a iapdev.us-east-1 -u ICA_U_277853 --authenticator=oauth -r ICA_UR_277853_603465_264891 -d atestbase2_264891 -s PUBLIC -w ATESTBASE2_264891_`**`LOAD`**` `` ``--token= `* 2. Execute the following statement after logging in : “*`use warehouse ATESTBASE2_264891_LOAD`”* To determine which warehouse you are using, execute : `select current_warehouse()`;
### Synchronizing Tables if you have [created tables](https://docs.snowflake.com/en/sql-reference/sql/create-table) directly in Snowflake with the OAuth token, you can synchronize them to appear in ICA by means of the **Projects > your\_project > Base > Tables > Sync** button. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.ica.illumina.com/project/p-base/base-snowflake.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
