Methods

CreateEntry(CreateEntryRequest, ServerCallContext)

public virtual Task<Entry> CreateEntry(CreateEntryRequest request, ServerCallContext context)

Creates an entry.

You can create entries only with 'FILESET', 'CLUSTER', 'DATA_STREAM', or custom types. Data Catalog automatically creates entries with other types during metadata ingestion from integrated systems.

You must enable the Data Catalog API in the project identified by the parent parameter. For more information, see Data Catalog resource project.

An entry group can have a maximum of 100,000 entries.

Parameters
Name Description
request CreateEntryRequest

The request received from the client.
context ServerCallContext

The context of the server-side call handler being invoked.
Returns
Type Description
TaskEntry

The response to send back to the client (wrapped by a task).

CreateEntryGroup(CreateEntryGroupRequest, ServerCallContext)

public virtual Task<EntryGroup> CreateEntryGroup(CreateEntryGroupRequest request, ServerCallContext context)

Creates an entry group.

An entry group contains logically related entries together with Cloud Identity and Access Management policies. These policies specify users who can create, edit, and view entries within entry groups.

Data Catalog automatically creates entry groups with names that start with the @ symbol for the following resources:

  • BigQuery entries (@bigquery)
  • Pub/Sub topics (@pubsub)
  • Dataproc Metastore services (@dataproc_metastore_{SERVICE_NAME_HASH})

You can create your own entry groups for Cloud Storage fileset entries and custom entries together with the corresponding IAM policies. User-created entry groups can't contain the @ symbol, it is reserved for automatically created groups.

Entry groups, like entries, can be searched.

A maximum of 10,000 entry groups may be created per organization across all locations.

You must enable the Data Catalog API in the project identified by the parent parameter. For more information, see Data Catalog resource project.
