# Configure Paths for Snowflake Background Tasks

Paths define which tables and views the discovery task or profiler task should work on. All paths need to be valid [regular expressions](https://docs.python.org/3.8/library/re.html#regular-expression-syntax). The regex is not case sensitive. [(see examples)](#examples)

## Discovery Paths

This controls, which objects should be available in the catalog and for the other tasks.

**Include:**

These data objects (databases, schemas, tables, views) will be indexed for the catalog. `<Empty>` includes everything. If multiple paths are specified, all of them are searched. Overlapping paths will only be indexed once.

**Exclude:**

These objects are excluded from the catalog. `<Empty>` excludes nothing.

An object in the excluded paths will always be excluded (even if it was included above).

## Examples

### Match all tables or views of a database

```
demo_db\..*
```

This would match all objects that start with `DEMO_DB.`. Please note that the `.`(dot) needs to be escaped otherwise it matches every character.

### Match all tables or views with certain names

Match all tables or views of a schema that start with `my_` and end with `deprecated`

```
my_database\.with_schema\.my_.*deprecated
```

It would match e.g. `MY_DATABASE.WITH_SCHEMA.my_temporary_table_deprecated`.
