Notes

• block_id column in our data models matches what Solcan classifies as Block. This value is same as what is referred to as Slot.

Applying Model Tags

Database / Schema level tags

Database and schema tags are applied via the add_database_or_schema_tags macro. These tags are inherited by their downstream objects. To add/modify tags call the appropriate tag set function within the macro.

{{ set_database_tag_value('SOME_DATABASE_TAG_KEY','SOME_DATABASE_TAG_VALUE') }}
{{ set_schema_tag_value('SOME_SCHEMA_TAG_KEY','SOME_SCHEMA_TAG_VALUE') }}

Model tags

To add/update a model's snowflake tags, add/modify the meta model property under config. Only table level tags are supported at this time via DBT.

{{ config(
    ...,
    meta={
        'database_tags':{
            'table': {
                'PURPOSE': 'SOME_PURPOSE'
            }
        }
    },
    ...
) }}

By default, model tags are not pushed to snowflake on each load. You can push a tag update for a model by specifying the UPDATE_SNOWFLAKE_TAGS project variable during a run.

dbt run --var '{"UPDATE_SNOWFLAKE_TAGS":True}' -s models/core/core__fact_swaps.sql

Querying for existing tags on a model in snowflake

select *
from table(solana.information_schema.tag_references('solana.core.fact_blocks', 'table'));
