* If you are migrating large amounts of data, consider increasing elasticsearch's
thread count via the `ELASTICSEARCH_THREAD_COUNT` environment variable.

#### Exclusions
You will likely want to exclude some urn types from your ingestion, as they contain instance-specific
metadata, such as settings, roles, policies, ingestion sources, and ingestion runs. For example, you
will likely want to start with this:

```yaml
source:
config:
urn_pattern: # URN pattern to ignore/include in the ingestion
deny:
# Ignores all datahub metadata where the urn matches the regex
- ^urn:li:role.* # Only exclude if you do not want to ingest roles
- ^urn:li:dataHubRole.* # Only exclude if you do not want to ingest roles
- ^urn:li:dataHubPolicy.* # Only exclude if you do not want to ingest policies
- ^urn:li:dataHubIngestionSource.* # Only exclude if you do not want to ingest ingestion sources
- ^urn:li:dataHubSecret.*
- ^urn:li:dataHubExecutionRequest.*
- ^urn:li:dataHubAccessToken.*
- ^urn:li:dataHubUpgrade.*
- ^urn:li:inviteToken.*
- ^urn:li:globalSettings.*
- ^urn:li:dataHubStepState.*
```
