public virtual Task<Operation> CreateIndex(CreateIndexRequest request, ServerCallContext context)
Creates the specified index.
A newly created index's initial state is CREATING. On completion of the
returned [google.longrunning.Operation][google.longrunning.Operation], the
state will be READY. If the index already exists, the call will return an
ALREADY_EXISTS status.
During index creation, the process could result in an error, in which
case the index will move to the ERROR state. The process can be recovered
by fixing the data that caused the error, removing the index with
[delete][google.datastore.admin.v1.DatastoreAdmin.DeleteIndex], then
re-creating the index with [create]
[google.datastore.admin.v1.DatastoreAdmin.CreateIndex].
public virtual Task<Operation> DeleteIndex(DeleteIndexRequest request, ServerCallContext context)
Deletes an existing index.
An index can only be deleted if it is in a READY or ERROR state. On
successful execution of the request, the index will be in a DELETING
[state][google.datastore.admin.v1.Index.State]. And on completion of the
returned [google.longrunning.Operation][google.longrunning.Operation], the
index will be removed.
During index deletion, the process could result in an error, in which
case the index will move to the ERROR state. The process can be recovered
by fixing the data that caused the error, followed by calling
[delete][google.datastore.admin.v1.DatastoreAdmin.DeleteIndex] again.
public virtual Task<Operation> ExportEntities(ExportEntitiesRequest request, ServerCallContext context)
Exports a copy of all or a subset of entities from Google Cloud Datastore
to another storage system, such as Google Cloud Storage. Recent updates to
entities may not be reflected in the export. The export occurs in the
background and its progress can be monitored and managed via the
Operation resource that is created. The output of an export may only be
used once the associated operation is done. If an export operation is
cancelled before completion it may leave partial data behind in Google
Cloud Storage.
public virtual Task<Operation> ImportEntities(ImportEntitiesRequest request, ServerCallContext context)
Imports entities into Google Cloud Datastore. Existing entities with the
same key are overwritten. The import occurs in the background and its
progress can be monitored and managed via the Operation resource that is
created. If an ImportEntities operation is cancelled, it is possible
that a subset of the data has already been imported to Cloud Datastore.
public virtual Task<ListIndexesResponse> ListIndexes(ListIndexesRequest request, ServerCallContext context)
Lists the indexes that match the specified filters. Datastore uses an
eventually consistent query to fetch the list of indexes and may
occasionally return stale results.
