> Technical validations performed before running the CrateDB crawler to verify connectivity and permissions

Before [running the CrateDB crawler](https://docs.atlan.com/llms/connectors/cratedb/crawl-cratedb/llms.txt), you can run [preflight checks](https://docs.atlan.com/llms/catalog/connector-capabilities/what-are-preflight-checks/llms.txt) to perform the necessary technical validations. The following preflight checks are completed:

## Database and schema check

✅ `Check successful`

❌ `Check failed for $missingObjectName`

## Tables check

✅ `Check successful. Table count: <count>`

❌ `Check failed. Missing some of the required grants SELECT, SHOW VIEW, EXECUTE on tables:`
